Fixing an HP G62 with Start Up Problem (In Pitt Meadows)
This HP G62 was traded in in July 2012. It could not be booted up. The keyboard had a missing key. Other than that, the laptop is in good comestic condition.
I disassembled the G62 and found that the laptap fan was clogged with dust. My instinct of the problem was video chip overheating. I inspected the video chip. It had not been attempted with improper reflow. I removed the red resin around the video chip and performed the video chip reflow on 21 Jul 2012 with patience and proper temperature. I cleaned up the laptop fan and re-applied new thermal compound on both the CPU and the video chip and added a copper shim for better heat conduction.
After re-assembling the G62 back, there were messages displayed at start up but it could not always go to the Windows desktop. When it can go to Windows desktop, it is normal. I remember that the owner told me that he changed the CPU setting to run game. I was thinking about BIOS might had been altered.
When the G62 started up normally, I refeshed the BIOS to the latest version from HP website. After the refresh, the G62 starts up normally every time. Since the laptop is in good shape, I ordered a new keyboard for it. When the keyboard arrived, I replaced the broken one. The HP recovery partition is inside the G62. At boot up, I pressed F11 to run the HP System Recovery and selected the Factory image restore option to clear any personal data that the previous owner may have left.
On 3Sep2012, over a month of the reflow, I tested the G62 again. It is running normally. The video chip reflow is good. A nice man from Pitt Meadows contacted me and picked it up on 29Sep2012. He traded in an Apple Powerbook G4 which is the first Apple that I have.
