Hello, I'm having trouble booting OS or entering BIOS.
When screen appears I press ESC and then ENTER when blue menu appears
If I choose Boot as normal or Select boot device F12 or Enter BIOS Setup F2 - only blinking cursor at top left corner
Only Lenovo diagnostic works:
No USB device is connected nor HDD.
Memory test passed.
CMOS battery - removed, BIOS reset, getting message about CMOS reset, but still cannot enter.
I have (from Lenovo Diagnostic):
Product Name: 3358BEG
ThingPad Edge E130
BIOS: H4ET92WW (2.52.)
I supsect BIOS is corrupted.
Does exist BIOS crisis recovery from USB or something?

Welcome to the Community Forums.
Please do a power drain first by removing all connected devices (ac adapter, USB flash drive, etc.), shut it down and hold down the power button for 60 seconds. Enter BIOS again with the different methods here, https://support.lenovo.com/us/en/solutions/ht500216. If same issue, possible motherboard issue. You need to contact support (https://pcsupport.lenovo.com/us/en/supportphonelist) for repairs.
