When totally cool, the laptop seems to boot just fine, but after a short time, screen goes blank and computer seems to just shut off, yet power light remains lit. I can turn it off by holding down the power button. Computer will not boot right away. Instead, fan turns on, cdrom reads, hard drive seems to spin, but fan shuts off after about 5 seconds with no beeps and nothing on-screen.
My best guess is that this is an overheating video chip issue because when it does boot, the video seems to constantly adjust luminosity up and down.
Before I bother ripping this thing apart, does anyone have any experience with fixing this same issue?
