I have Ultrabook Acer aspire s3-391-73514G52 motherboard number HM2-CR UMA 48.4TH02.021 12201-2.
The unit powerup , fan spins then it shut down no post screen and boots again in same sequence. The blue led flashes on and off with no sequence.
pl4101 has 3.4v on it then 0v when reboot
pl4502 1v then 0v when reboot
pl4301 .8v then 0v when reboot
pl4401 0v
pl4601 1.5v then 0v when reboot
pl4103 5v then 0v when reboot
Cmos battery voltage is ok.
I have not flashed the bios yet.
Any ideas are appreciated
