Hi everyone,
I have a HP DV5-1125NR laptop that someone gave me because it overheated. after various tests i determined that it was a defective heatsink because the HS was getting very hot but the fan was blowing out cold air. Got a new heatsink and reseated it exactly like the original. i put new arctic silver thermal paste on it to ensure proper heat conduction. when i buttoned everything back up, the system wouldnt boot. The caps lock and numlock lights were blinking an error code. i did some research and i found (on HPs support WS) that the blink code i was encountering means CPU failure. the CPU had worked BEFORE i replaced the heatsink. i put the original HS back on, still not working. This laptop is out of warranty, and it costs about 400-500 bucks to ship it to HP to fix it, when for about 80 bucks (30 heatsink, 50 new CPU) i can repair it myself. ive already replaced the heatsink which solved the original issue, because now the so determined “dead” CPU is getting hot and the fans airflow is also hot air like it should be. so the heatsink is fixed. Now i have to figure out if the CPU really is bad. i was careful in handling all the items, so no static shock would damage it. but according to the bios blink code, the CPU is bad. What do you think? i can get a new processor on ebay for about 50 bucks, but before i make the investment i want to be for sure that it is the problem.
Any tips or pointers welcomed. If it means me getting my free laptop working again, then im willing to do it 🙂
Here are the specs:
HP DV5 Bronze series
DV5-1025NR
Windows Vista HP 64-bit
AMD Turion 64 X2 @2.0GHz
4GB DDR2 RAM
250GB WD SATA HDD
I tried removing the CMOS battery and clearing the CMOS, but the error code still appears. Also, before it died, I updated it to the latest BIOS revision.
What should I do now?
Thanks in advance,
Corey
