Some things are worth waiting for, others no so much. :-( So, this laptop was taking longer and longer and longer to boot, until it eventually stopped booting 3-4 months ago: When the power button is pressed the cooling fan spins for a second or two, then it stops. A few minutes later the CPU overheats and eventually it goes into a thermal shutdown. Using an external fan to push air through merely delays this process, but the laptop still does not boot. I am getting a black screen and no POST for many minutes until it cuts out. I tried to reset the MoBo BIOS by pressing the power button with no battery or mains connected. I also removed the newly replaced CMOS/RTC battery and pressed the power button, but the same failure mode remains after I reassembled everything. Do I have: 1. Corrupted MoBo UEFI firmware? 2. A dying/dead chipset? 3. Something else? Is there anything else I could possibly try? --nextPart3521127.QJadu78ljV Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part.
