Hello everyone,

I'm new here and I am having some laptop issues and was hoping someone might be able to assist me with them. First I would like to list my computer specs:

HP DV9543CL laptop
Intel Core 2 Duo T7300 2GHZ
2x 160 GB SATA HDs
2 GB RAM
Running: Windows 7 x64

Below is a rundown of what is happening and what I have done to try and resolve my issue:


My laptop was making some retched loud noises from the fan and it wouldn’t stop or slow down at all, it would just stay on with its highest RPMs. With my warranty expired, I decided I would open up my laptop to try and clean out the fan and heatsink. I have worked on and built my own desktops for a while and I decided that I should be able to clean the laptop fan (a decision I currently regret). I got everything open and took everything apart and cleaned out the fan and as I was putting the laptop together I had a hard time putting in the flat cable for the HP Quickplay Switch Board and slightly damaged it. After everything was put back together, I fired up the computer and everything booted up properly. I noticed that the HP Quickplay buttons lights still came on, but the volume slider lights were no longer illuminated. The Quickplay buttons no longer work (which I can deal with because they illuminate properly) but I am having a bigger issue now.

I noticed when I booted up Windows, my battery icon showed that my battery was charging but when I hovered over the icon it said my battery had 0% but was plugged in and charging, however the percentage would never increase indicating it was actually charging. I thought this was weird so I decided to unplug the laptop from the AC adapter to see what would happen. When I did this, the computer stayed on but still told me that the battery had 0%. I decided to leave it that way (since I knew the battery had an almost complete charge) and check to make sure everything else worked. After about 5 minutes or so, my computer shut down instantaneously (like if you were to pull the plug without the battery in.) Knowing this was a bad sign, I decided to try and figure out what was going on. I tried plugging in the computer with the battery in and after about 10 minutes or so the computer shut down the same way. Next I thought I would try using the laptop without the battery in and use it on just AC power. This seemed to work and since I have been using the laptop this way, it has been running alright. My wife has the same exact laptop so I thought I would check my battery in her computer and her battery in mine because her computer is running fine, and, of course, her battery does the same thing in my computer and my battery reads just fine in her computer. So I am now resorting to working on my laptop only on AC power, but I’m sure you can understand my frustration in using a laptop this way. I also thought maybe it was a software issue in my Windows OS so I loaded up a Ubuntu live boot environment and found that Ubuntu was reporting the same battery issues as Windows (saying the battery was charging at 0% but not increasing in charge and reporting that the battery was empty when off of AC power but still running for a short time.)
There is one other issue that is happening. If I leave the computer on with the battery in (with or without AC power) and leave it sitting, eventually the battery charging indicator light starts flashing as if something is wrong. This also happened when I had the computer completely off but left the AC adapter plugged in with the battery in (as if to charge the battery). This led me to believe that the issue is a hardware issue but I had to check to make sure it wasn’t an OS problem as well.

I really have no idea what I could have done to the computer to have this happen. I checked everything that I did when disassembling the computer and I didn’t tinker with the battery or anything that controls it, to my knowledge. If anyone has any ideas or suggestions it would be greatly appreciated. I really regret ever opening up my laptop but now that it’s in the past, I’m hoping I may be able to at least fix what I’ve messed up.

Sorry for such a long post and thank you, in advance, for helping me with my issue. Let me know if there is any other information you may need to assist. Thank you for your time.

Re: HP DV9000 Laptop Instant Shutdown Battery Issue

So I just had another shutdown but this time it was without the battery in and on AC power (which was working fine before). I decided I would load up World of Warcraft to play, since I thought it was working, and after about 5 or 10 minutes of playing the computer shut down. It doesn't restart when these shutdowns happen it just goes off and stays off. I have been monitoring temperatures to see if that could be a potential issue of overheating (although I still think there is a battery problem too) and found that just random web browsing has the computer idle around 44-45 C and when I am running World of Warcraft it was ~80 C. I don't know what normal laptop temps are but it didn't seem overly stressing but I don't know. It's working for normal web browsing and word processing but World of Warcraft is too stressing apparently. Any insight anyone has on this issue would be wonderful. Thanks for your time.

Bump!

Does anyone else have any ideas on this issue? Anything other than a motherboard issue or does that seem likely?

I am now having it shut down during some more stressing applications, besides World of Warcraft, now as well including in iTunes when I am trying to have it analyze my music to start Genius or in Ubuntu when I was playing music while adding my music library to the Banshee library and installing system updates.

If anyone has any insight into this issue, it would be greatly appreciated.

Hello Billy88 and welcome to TSF,

Firstly, I would check the damaged cable to be sure it is not shorting to the motherboard.

Secondly, when you took your computer apart, did you remove the heatsink from the CPU?

Just removed the damaged Quickplay Switch cable and, sure enough, my battery was instantly recognized and no shut downs at all even though I had music running while running WoW and having iTunes analyze my music for Genius mixing. Thank you so much for the suggestion and it looks as though everything is working perfectly again. Just a motherboard short from a faulty cable... I hate those flat laptop cables...

Thanks everyone!
