laptop reboots

TXNewbieRepair · 04-11-2008, 09:23 PM

I am having a very similiar situation myself. We have an HP Pavilion dv9000 (dv9008nr). My boyfriend was using it one day, finished his internet surfing and powered it down. Few hours later he went to turn it back on--and nothing.

When you push the power button, the lights on the kb light up, the cd drive does it's little two part noise, and I can hear the HD start to spin. The fan, however, will start to spin for like a second after I hear the cd drive, and then it stops. The LCD stays black, doesn't even flicker, the HD continues to spin and then it will "reboot". This cycle will continue until I do a hard shutdown.

After searching these forums (plus the HP site, and no it's no longer under warranty) here is what I have done:
-Tried booting with only the AC power and no battery (Tried different power outlets just to be sure)
-Tried battery and no AC cord
-Reseated the RAM
-Tried each memory stick (it has 1-1GB and 1-512MB ) by themselves in each of the different slots (on AC power only w/ the battery out)

I don't have any extra memory to try so I'm not sure if it's the memory or the CPU.

Any suggestions are much, much appreciated as this is my boyfriend's WoW laptop! lol ;)

do you get anything in safe mode
download and run the hard drive makers diognostic utility on the hard drive

TXNewbieRepair · 04-11-2008, 09:56 PM

I wish I could get to safe mode...at least then I'd feel like there's hope. I neglected to mention that nothing shows on the screen at all. Nada, kaput, nothing, black hole.

So basically, it shows that it's getting power, but it doesn't even go to the HP screen or anything. The screen stays entirely black.

shine a torch on the screen and see if you see anything

TXNewbieRepair · 04-11-2008, 10:06 PM

Nada....I did briefly seem some color as if the LCD was trying to come one, but no lights.

EDIT:
When I say color, I mean color like when you push your finger against an LCD screen. Not a backlit color.

Also, I just tried powering it on again and it actually came on, so I went to BIOS and tried to run diagnostics. Said that no diagnostics were found and that there was no IDE device present. Exited BIOS and it "rebooted" to the same behavior as before. Hasn't come back since.

can you connect and external monitor

TXNewbieRepair · 04-11-2008, 10:45 PM

Yeah...but that will require me to crawl behind my desk and unhook this desktop. I will gladly try this tomorrow when it's not so late.

it will indicate if it is the screen or the video chip
remove the hard drive and if it boots normally and you see the post screens it indicates it's the hard drive

TXNewbieRepair · 04-12-2008, 08:25 PM

OK, hooked it up to an external monitor--no change.
Pulled the HD and turned on--no change.

dai · 04-12-2008, 08:40 PM

would suspect the video chip or the m/board

TXNewbieRepair · 04-14-2008, 06:51 PM

A bit of an update...been messing around with it some more and found that now, everytime I mess with the memory, I can get it to boot. I can go into either BIOS or boot to Windows. But if I restart from either, it won't come back up. It just sits and reboots itself while not displaying anything on the screen. At this point, I'm starting to think CPU, so I might give that a shot.

oh no. mess with the RAM again until you get it to boot.
check these documents out and see if they apply to your situation...

then download and install this:

Thank you for the suggestions on the threads, but I don't think those quite apply to me. The laptop has a 1.6GHz AMD Turion 64x2 Dual-Core processor. Unless the .exe you posted would apply to an AMD processor. (Which I kinda doubt but you never know...) If so, do you think you could you repost the link? Everytime I click on it, it tells me "Error 403: Request Forbidden".

Thanks a bunch!

sorry about that.. my bad. the exe file is from Microsoft and as per the Microsoft KB is for Intel processors. laptop2go website made it public but Microsoft has not made it public yet. in fact you can request the fix from the Microsoft links in the previous post if you want to try it.

although here is something that might interest you. check this out and see if it matches your laptop's situation...

HP and Compaq Notebook Users look here!

TXNewbieRepair · 04-16-2008, 01:35 PM

Hmm...thanks for that. I will have to check that out when I get home from work tonight. My work tends to frown on me working on my personal pc's here when I'm on their time...I have no idea why...LOL

Also, no apologies necessary about the type of processor--I'm the one who didn't post the specs! :)
