Hi from snowing Estonia.
I have problem with ThinkPad 570E.
It's freezes on startup. Can't go to the bios.
Shows only logo and F1 go to BIOs an F12 boot....
That's all.
The power on indicator is off. (all the time)
The others are blinking 2 times.
I tried with no HDD, modem, battery- both.
One night worked and in the morning it doesn't.
Any ideas? |

1. BIOS corrupted.
2. Embedded COntroller problem - damaged or FW corrupted.
3. Bad power controllers, power mosfets or regulators. EC cannot validate power good status.
If one night worked, then I'd go for a power problem. |
