HP Pavilion dv9000 crashes after extended non-use time

memmons111 · 01-17-2008, 06:19 AM

I have a HP Pavillion dv9000 laptop, 17" wide screen, 2 Gb RAM, running Vista Home Premium. I leave it running all the time and close the lid when I am done. The computer works fine except that after an extended time of non-use (over night) the screen stays black (not even backlit) when I open the lid. The power and all the lights are on but the disk light does not come on. The only thing I can do then is hard-boot by holding the power button down for several seconds. The computer will then boot back up and run fine. I have set all the power settings to "never" or "do nothing" when using AC power but that hasn't helped. I have called HP but their only suggestion was to turn off the computer when I was done with it. DuH. Any thoughts??

Hi memmons111!!

I'm bhahar

It seems like you're having a issue with the sleep mode. I'm afraid that HP technical support person advice might be right. It might be one of the most common issue in Vista. However, you can try to wake your laptop from sleep, and try pressing a few buttons on your keyboard for almost 10-15 seconds, see whether you can get your monitor back on. If its not, might consider wait for proper updates from microsoft then

memmons111 · 01-22-2008, 06:32 AM

I have taken a new approach. I have changed the go to sleep setting to 30 minutes. I have confirmed that I can put the computer to sleep and wake it up by pressing the power button. I figure that if the computer is in sleep that it won't crash and when I come back to the computer a day later that it will be in sleep mode. I have since experienced the crash even before the 30 minute timer expires so now I don't know what the crash is related to. I am searching Microsoft Vista help now looking for hot fixes. No luck yet. Maybe I will manually put the computer to sleep before I shut the cover when I am done for a while.

Hi memmons111,
It is possible this unit is Overheating, causing the crash. Laptops are not like Towers in that towers have alot of fans to keep them cool. A laptop usually has only one fan, This results in poor cooling. Check the vents on this laptop and see if they are plugged. If they are use a can of compressed air to blow them out. I would also reccomend a quality cooling pad if you intend to run this laptop constantly.
Hope this helps.
Bill

memmons111 · 02-05-2008, 12:01 PM

Thanks for the inputs. I bought a USB powered cooling pad but that didn't make any difference. As time has gone on the Computer started locking up while I was using it. With HP Service help (they have been great and anxious to help and verify the fix) I booted up and immediately started pressing F11 which took me to a screen to begin reloading Windows Vista and all the preload programs. Although this is extreme and I lost all my applications I had loaded myself, it seems to have solved the problem (at least for now). HP is calling me every week for 3 weeks to check on status.

bhahar84 · 02-06-2008, 07:08 AM

It seems like you have done the system recovery, which returns your computer back to factory settings, right

Ok, try to use the computer, and post back if you still facing the same issue

memmons111 · 02-08-2008, 08:17 AM

Well, I thought I had responded to Bhahar84's last post but I don't see it here. So I will respond again. I did effectively return to the Factory setting. I did this last Saturday and I haven't had any crashes (lockups) since. I have run it 24 hrs per day and no problems (knock on wood). I do notice that the computer does not go into sleep mode even though I have selected to go to sleep after 2 hrs of inactivity (except for the first time after a bootup). There may be "things" going on that effectively keeps restarting the "period of inactivity". Interesting, but so far so good on the no crashes through 6 days. HP will call me the next three Saturdays to check up on it.

**BCCOMP** · 02-08-2008, 02:58 PM

HI,
I would also recommened that you use an additional cooling pad of quaility (not price). A laptop was designed for portability, not consistent use. Laptops at the most have 2 fans, as apposed to a tower that may have 4 fans or better. In other words laptops are not designed for LONG term use. If you must run a laptop for a period of time (2 of mine are none stop 24/7, but with a GOOD cooling pad), you will need additional cooling pad of some good quaility design (*not the $19.99 specials) to prevent OVERHEATING.
Thanks,
Bill

While researching the problem with my DV9005 laptop I stumbled on this post by memmons111. Here's what I know: I purchased an HP DV9005US model in January 2007. It performed flawlessly until last Sunday (2/24/2008). That afternoon, while it sat in screensaver mode for about 4 hours, it locked up (no hard drive activity light, no response to keyboard, ctrl-alt-delete does nothing). I had to power it down with the Power Switch held down for 5 seconds. It then booted OK. For the next five days it would freeze about twice per day at any time. Sometimes while not actively in use, sometimes while I was keying in data to my word processor. I thought it might be software since I had recently installed two conferencing pieces of software (Gtalk and Skype) and I knew they would be lurking in the machine all the time. I removed these and still had the lockup problem. I then booted my LiveCD of MEPIS Linux, which got WindowsXP completely out of the picture, and the machine still locked up. Aha! Gotta be hardware. Under WindowsXP again, I fired up the Help and Support software from the Start button and ran through the HP quick system test. It passed OK. I ran specific test against Memory, Processor, PCI-bus, and Video sections. All without any error. Then I noticed an "Advanced Test" options where you can test memory and two other things (I can't remember what and can't tell you because my machine is broken at the moment, I'm using an older Toshiba laptop to type this). I started the memory test and it got to the 13% range and the machine froze. After powering down it has now refused to power up. I see a flicker of the hard drive light (or, if I've got my MEPIS CD in the CD drive, the CD activity light will flicker for about ten seconds) but the screen stays black. Now, for the good news. HP sent me an email last December stating two things: (1) there was a "critical" update to the BIOS (brings it to level F3D, I believe) that I should flash. I did this in January without trouble. It had something to do with the fan control. These laptops run hot these days and they want to extend their life, I suppose. (2) the DV9000 series (and DV6000, also) are susceptible to a hardware failure that causes one or more of a list of 7 things to go wrong. Some of these are (a) wireless card is not recognized (b) machine won't power up and leaves blank screen (c) ... HP has agreed to extend the warranty on these machines, for this problem only, an additional year. Go to
http://h10025.www1.hp.com/ewfrf/wc/p...&lang=en&cc=us for more info. Or simply work your way thru www.hp.com to find it. There is a specific match of p/n (EZ453UA in my case, for my DV9005) that tells if your machine is included in the extended service. Right now I'm awaiting a shipping box from FEDEX to send the machine to HP for repair, which they said would take about 9 days. The phone number I called was 1-866-671-7362 (6a-11p MST, Sun thru Sat). The representative I got was a girl in the Philippines, but the chat was professional. She had me reseat the memory boards and the hard drive, all to no avail. I knew this wouldn't work because I had put the original 1GB memory back in, replacing the 2GB I had installed last Thanksgiving just to see if that was the problem. What I'm trying to find out now by scrounging thru the internet is the true nature of the hardware problem. It sort of smacks like power supply to crucial (aren't they all crucial?) circuits is faulty and the ability of the processor to execute instructions is kaput. In your case I really don't think your setting of powersave options will make any difference. I had my machine freeze just 2 minutes after booting! There's a weak piece of hardware, HP knows it, and will replace it free (shipping included) if your machine is in their list.

HI Tim,
Thanks for the reply on this. It looks like you have done alot of research that may help others. I would like to know if HP gives in and tells you what the exact problem may be.
Anyway, I do not think they will admit to it, but people with the same problems as yours may benefit from your post.
Thanks,
Bill

dv9005user · 03-02-2008, 08:15 PM

OK, I've found some information at

http://blogs.zdnet.com/Berlind/?p=853

and

http://www.pcmech.com/article/hp-pav...tebook-review/
(see post #92 by "Technical Guru")

that seem to pin down the basic trouble with my DV9005 notebook as being a control chip on the motherboard that handles the built-in WiFi. It sounds like a replacement of the motherboard is HP's solution. I feel bad for HP. I really like my machine. I've owned 4 Toshibas in the past (actually, they're all still in my house and usable: I'm using one of them right now to type this!) and have replaced two crashed hard drives (my son is rough on them, my own have never failed), a cooling fan, and the "inverter" board for an LCD display (it runs hot with high voltage). These problems have been tolerable, but this HP motherboard issue is scary. I simply hope they have figured out exactly what it is and are willing to do what is necessary to my machine to totally eliminate it. People these days rely on their machines and I'm one of them.

dv9005user · 03-03-2008, 11:04 AM

I received my shipping materials from HP this morning and I'm sending the laptop to HP in California this afternoon via FEDEX. I did one last attempt to boot it with the battery removed and only on A/C adapter, but no success, just a blank screen.

Tim O

**BCCOMP** · 03-03-2008, 03:41 PM

Hi Tim O,
I think HP should resolve this with the new MoBo. I just do not know why you, as a consumer has to put up with this (It is WELL documented).
Hopefully, HP will fix this for you (at NO charge).
Let us know how you make out!
Thanks,
Bill

Paperweight · 03-04-2008, 07:30 AM

Exact same thing happened to my hp dv2000. After trying to bring it back out of sleep, all I got was a black screen. Called hp and they wanted me to send it to the depot. They gave me a 2-6 week time frame so I decided to take it to best buy because I needed it for school. Best buy called me back in a week and told me hp is going to buy me a new notebook because the repair would be to much(im guessing the mobo). I ended up with a Toshiba Satellite: 2.2ghz dual amd, 3gb of ram, and a ATI radeon 2400. A big upgrade from my 1gig, 1.8 amd, nvidia 6800 hp dv2000. :)

thanks hp.

Yup, it seems like it might be an internal hardware issue. the HP will replace the part, and do a test through all the system once, to make sure it was working fine before send it back to you again

Hi Paperweight, did the HP replaced the whole unit for you?

dv9005user · 03-04-2008, 02:16 PM

As of 9AM today they received my DV9005. Boy, if Paperweight gets a new machine (from a competitor, at that) via HP then he's doin' great. I'm not asking for that much. But I've been buying home computers since 1983 (Commodore VIC-20, Commodore-128, IBM PS/2 Model 50, Custom-built 486/50MHz, and four Toshiba laptops (315CDS, 2515-CDS, 2805-Sxxx, 1415-S105) and *never* had any problems with motherboards. This is a first for me. I only worry that some forum comments led me to believe HP was replacing the mobo with another just like it and hoping for the best. That's not good. A little more heat sink goop on the same circuitry is not thorough enough for me. I've never believed in stressing stuff. You don't get your money's worth that way.

dv9005user · 03-06-2008, 08:05 AM

I got an email from HP that my DV9005 has been repaired and has been sent overnight shipping yesterday. It may arrive today. I just remembered this morning that a couple months ago my machine would randomly issue a message something like "Windows has discovered new hardware and is installing a driver to manage it: WiFi card". This happened half-a-dozen times over a period of about three weeks. I was puzzled at the time but chalked it up to flaky software. Now I know this is the clincher for proving it's a hardware problem with my machine. Namely, the Broadcom WiFi chip itself or an interface chip that connects it to the system bus. This disappearance and reappearance of WiFi connectivity has been reported by many others. In my case I was never without WiFi more than a few seconds so it didn't register with me how serious the problem was. I'll report back when I examine the repaired machine.

Tim O

bhahar84 · 03-06-2008, 10:40 AM

Ok

Try to check throughly the system after you received it, and post back how it goes then

dv9005user · 03-07-2008, 02:42 PM

I got my DV9005 back from HP at 11AM this morning. Since it was cold from riding in the FEDEX truck here in western Pennsylvania, USA I let it acclimate for two hours. The Repair Receipt indicated they replaced the "system board" and the "heatsink fan" just as others have reported. Before shipping the laptop on Monday I had taken pictures of the machine through the removed cover of the user-expandable memory upgrade panel. Upon examining this same area today I could see that the Broadcom 4311 WiFi chip (on its own daughter board above the system board) had not been changed but the sockets for that daughter board and the main RAM memory were different so obviously the system board was replaced. Hey, I'm not doubting HP on that point! From what I've been able to ascertain on various forums the NVidia NF430 chip on the system board, which fortunately is easily visible under this removed cover, is what causes the trouble by overheating. I found my new system board had a Taiwan-made version of the same chip and it had a bead of bright red heat-sink paste running around its periphery. The original NF430 was made in Korea and had no visible heat-sink paste. I had not seen any melted solder spots on the old NF430 but I'm no expert in such things. Anyway, I booted up and was delighted to see my hard drive was completely intact so no data was lost (my last backup was about two weeks old). Thanks, HP! Also, there was no cosmetic damage anywhere and, in fact, they had made a slight adjustment to the two fasteners that latch the LCD cover to the keyboard when you close it so I can now open the unit without having to pry open the left-hand latch. I decided to use the "Help and Support" software from the Start menu and ran through the 2-minute system test followed by specific tests on the Processor, Video, Memory, and PCI bus. These passed without problem, just as they had before the machine died on me last Friday. I then ran the Advanced Memory test, which took 56 minutes, since this is the test that was running last Friday when the machine froze and refused to boot. It just finished that test without problem. So now I have a machine running well again, and the only question is for how long?

I remember about 20 years ago when I bought a new General Electric refrigerator expecting it to last me for decades. It quit cooling because GE had decided to "try" a rotary vane compressor in the Freon cycle. They were all failing after about three years. GE recognized the problem and replaced the compressors with standard piston types that had been in use since refrigerators were invented in the 1920s. They did this "at cost", which meant I had to pay about $200, but at least I knew this would never happen again. I still have that refrigerator to this day. I wish HP could give me some confidence about this NF430 chip. Have they arranged for a newer MIL-SPEC version of it that we can all trust? I guess it doesn't pay to worry for now.

bhahar84 · 03-08-2008, 08:41 PM

Well glad to hear that you get the laptop working fine again

About the "how long it would work?", I think we just have to wait and see. Try use the laptop as usual and see if there is anything wrong happen on the laptop again. Otherwise, you can be happy the laptop was working as usual again

I did one last attempt to boot it with the battery removed and only on A/C adapter, but no success, just a blank screen. Tim O

I just do not know why you, as a consumer has to put up with this (It is WELL documented). Hopefully, HP will fix this for you (at NO charge). Let us know how you make out!

After trying to bring it back out of sleep, all I got was a black screen. Called hp and they wanted me to send it to the depot. They gave me a 2-6 week time frame so I decided to take it to best buy because I needed it for school. Best buy called me back in a week and told me hp is going to buy me a new notebook because the repair would be to much(im guessing the mobo). I ended up with a Toshiba Satellite: 2.2ghz dual amd, 3gb of ram, and a ATI radeon 2400. A big upgrade from my 1gig, 1.8 amd, nvidia 6800 hp dv2000. :) thanks hp.

Boy, if Paperweight gets a new machine (from a competitor, at that) via HP then he's doin' great. I'm not asking for that much. But I've been buying home computers since 1983 (Commodore VIC-20, Commodore-128, IBM PS/2 Model 50, Custom-built 486/50MHz, and four Toshiba laptops (315CDS, 2515-CDS, 2805-Sxxx, 1415-S105) and never had any problems with motherboards. This is a first for me. I only worry that some forum comments led me to believe HP was replacing the mobo with another just like it and hoping for the best. That's not good. A little more heat sink goop on the same circuitry is not thorough enough for me. I've never believed in stressing stuff. You don't get your money's worth that way. Tim O

dv9005user Registered User Join Date: Mar 2008 Posts: 16 OS: WinXP	Repaired machine shipped I got an email from HP that my DV9005 has been repaired and has been sent overnight shipping yesterday. It may arrive today. I just remembered this morning that a couple months ago my machine would randomly issue a message something like "Windows has discovered new hardware and is installing a driver to manage it: WiFi card". This happened half-a-dozen times over a period of about three weeks. I was puzzled at the time but chalked it up to flaky software. Now I know this is the clincher for proving it's a hardware problem with my machine. Namely, the Broadcom WiFi chip itself or an interface chip that connects it to the system bus. This disappearance and reappearance of WiFi connectivity has been reported by many others. In my case I was never without WiFi more than a few seconds so it didn't register with me how serious the problem was. I'll report back when I examine the repaired machine. Tim O

dv9005user Registered User Join Date: Mar 2008 Posts: 16 OS: WinXP	Repaired system works OK I got my DV9005 back from HP at 11AM this morning. Since it was cold from riding in the FEDEX truck here in western Pennsylvania, USA I let it acclimate for two hours. The Repair Receipt indicated they replaced the "system board" and the "heatsink fan" just as others have reported. Before shipping the laptop on Monday I had taken pictures of the machine through the removed cover of the user-expandable memory upgrade panel. Upon examining this same area today I could see that the Broadcom 4311 WiFi chip (on its own daughter board above the system board) had not been changed but the sockets for that daughter board and the main RAM memory were different so obviously the system board was replaced. Hey, I'm not doubting HP on that point! From what I've been able to ascertain on various forums the NVidia NF430 chip on the system board, which fortunately is easily visible under this removed cover, is what causes the trouble by overheating. I found my new system board had a Taiwan-made version of the same chip and it had a bead of bright red heat-sink paste running around its periphery. The original NF430 was made in Korea and had no visible heat-sink paste. I had not seen any melted solder spots on the old NF430 but I'm no expert in such things. Anyway, I booted up and was delighted to see my hard drive was completely intact so no data was lost (my last backup was about two weeks old). Thanks, HP! Also, there was no cosmetic damage anywhere and, in fact, they had made a slight adjustment to the two fasteners that latch the LCD cover to the keyboard when you close it so I can now open the unit without having to pry open the left-hand latch. I decided to use the "Help and Support" software from the Start menu and ran through the 2-minute system test followed by specific tests on the Processor, Video, Memory, and PCI bus. These passed without problem, just as they had before the machine died on me last Friday. I then ran the Advanced Memory test, which took 56 minutes, since this is the test that was running last Friday when the machine froze and refused to boot. It just finished that test without problem. So now I have a machine running well again, and the only question is for how long? I remember about 20 years ago when I bought a new General Electric refrigerator expecting it to last me for decades. It quit cooling because GE had decided to "try" a rotary vane compressor in the Freon cycle. They were all failing after about three years. GE recognized the problem and replaced the compressors with standard piston types that had been in use since refrigerators were invented in the 1920s. They did this "at cost", which meant I had to pay about $200, but at least I knew this would never happen again. I still have that refrigerator to this day. I wish HP could give me some confidence about this NF430 chip. Have they arranged for a newer MIL-SPEC version of it that we can all trust? I guess it doesn't pay to worry for now. Tim O

Try use the laptop as usual and see if there is anything wrong happen on the laptop again. Otherwise, you can be happy the laptop was working as usual again __________________ .:CPU-Z::Power Supply::Recuva::Unlocker::SensorsView::PSU Calculator::Everest:.
