HP DV7-4060us Blinking capslock? It's not Processor failure. Solution.

Now then. I picked up a DV7-4060us with the triple core AMD Phenom processor the other day for 20 bux without a hard drive or ram. Owner stated, doesnt work, had taken it to a computer shop, they said its the motherbaord. Okay.

So I take it home, try usb bios reflash, no go. Capslock light blinks, no other lights, sounds, nothing.

Ok. So I open it, get my harborfreight heating gun and heat up both the video chips. The AMD one and the ATi one. As shown in picture below.



As soon as I put it all together and plug it in, it starts working and has been, constantly since two weeks ago. This laptop has not been turned off, standby nothing. Works perfectly. Sound, video, HDMI port all alive. Still switches video cards when you unplug the power adapter.

Hope this helps.

Also, this same solution worked for a Compaq Presario CQ60. That laptop didnt pickup the bios reflash either no matter what I tried. Turned on immediately after heating the video chip.

 

I had a similar model, which I sent off to have the same thing done... Lasted about six months, unfortunately, and the video chip is back to its antics again.

Does anyone know the date range where HP was having this issue on consumer model systems, so I can avoid used ones with the issue?
