Antwort auf „no display, only screen glows,over heating problem to display card”I repaired a DV2810us following the method described by Adolfo and it worked great. After covering the board in aluminum foil and only exposing the video/chipset chip, I used the heat gun on low ~700F for about 40 seconds. Hellus also had a good suggestion that I did and that was to replace the thermal pad with a copper shim. A very, very thin layer of AS5 finished it up. IMHO I would not run any kind of processor with out a heat sink since you cannot control the temps and any damage will start internally and it will be too late by the time you see it.
Antwort auf „wont power up with power plugged to it”I have a C700 that had this same problem except it was the PQ2 chip. I tried to replace it without success. I had read others having luck just bypassing the chip with a jumper. I tried this and the laptop has been running fine now for a couple of months. I would recommend using the correct replacement if possible.
