HP DV6910us doesn't turn on

Here's the story. I bought an HP DV6910us for cheap on ebay cause it overheated. I figured it was dust-related and, yep. That's what it was. It also had a couple other small issues such as one broken USB port and the DVD drive was reading, lightign up, but not detected by BIOS. Anyways, so I redid the thermal paste and cleaned out the heatsink and fan. It ran a lot cooler and worked pretty nicely... it came with a stock image of Vista straight from the recovery partition. I hate how bloated it was (HP puts a lot of crap on there) and I don't even like Vista to begin with, so I installed via USB Windows 7. The weird thing is that 7 wouldn't boot unless I left the external drive with the 7 installer plugged in (even with the boot order to boot first from the internal drive). After installing all the updates and drivers, this still occurred. Without the external, it would hang on "Starting Windows." Safe Mode froze at CLASSPNP.SYS." I tried booting it without the DVD drive attached, tried removing all the RAM (which I took from another computer, I know its fine), and had 3 modules I tried one at a time, same thing. I rewrote the BCD and tried sfc /scannow but no dice either. It boots fine if I had the external drive plugged in. So I thought of updating the BIOS to the latest one. I got the right version from hp's site (It's an AMD processor), ran the program... it asked for confirmation to the latest version and I said okay. It was writing blocks to it and I looked away on my desktop monitor for a couple minutes when the hp shut down. I tried turning it on again and nothing. No fan, no lights, nada. I tried a hard reset, taking out the CMOS battery for a while, turnign it on without the battery, nothing works. The only sign of life it shows is that if I plug in the charger, the blue ring lights up to indicate its plugged in and if the battery is installed, it will light the charge icon.

I've worked on a few of these hps from this generation and they're honestly not the best machines around, but I was really hoping to sell this for profit. Unfortunately, I can't even get it to turn on at all anymore.

Here's a picture of how bad the dust was. http://i.imgur.com/wUyimfc.jpg

BIOS update failed. You will need the floppy method to reflash the BIOS. I recall the exact instructions but if you look on the HDX 9000 Dragon thread's 1st post, you will find the methodology regarding how to use a floppy disk to reflash the BIOS.

Otherwise, you will need to get a new mobo.

 

I have no external floppy drive. :/

 

You might try making a DOS bootable flash drive and then extracting the BIOS files (ending in .DVD or .BIN) and placing those on the drive.

See this post for an idea: http://forum.notebookreview.com/hp-...dragon-owners-lounge-2-a-172.html#post7213514

Also, if you get it working again, look into the various methods of using a flash drive to install Win7. What you described shouldn't have happened. Seems like there was a step or two missed when you created that USB install drive.

 

I created the USB drive the same exact way I have for other Windows 7 installs and I even made it multiple times. The laptop just is finicky. I never had any issues installing XP/Vista/7/8 via USB.

I made a USB bootable disk like you said but the machine doesn't even turn on at all.

 

GPU is done, then. That series had the Nvidia solder bump issue. You would need a new mobo.

 

Alrighty. I sold it on eBay for... not a lot. Someone else can use it for parts since everything else worked fine.
