W540 not booting up.

2019-12-29, 19:45 PM

I have a used W540 Thinkpad running Windows 10 Pro. After a few months of non use with power cord unplugged, I attempt to power up.laptop.

It went through BIOS screen but stopped. Keyboard backlighting, Fn button and F1 and F4 buttons blinks. Power button, dot on i in ThinkPad logo on laptop cover both blink three times, pause and blink three times in pattern. The fans whoosh in time with keyboard blinking but do not spin. 

I have tried following solutions to no avail: removed battery and unplugged power cord and pressed powered button 10 times. I removed second HDD and powered up laptop.

Please help.

One possibility is that your battery has been drained since you mentioned your rather aged laptop is left unplugged for a few months.

Try to leave it plugged in for a while (let say an hour) and start the laptop again.

Hi,
Check your BIOS battery and settings. If the battery went dead, the BIOS settings could be corrupted.
