Blank Screen - Flashing Power and Caps Lock buttons

2021-05-04, 14:45 PM

Not a complete newbie, but also not super tech knowledgeable. I have a 2 year old Lenovo Thinkpad E570. I started getting the BSOD indicating I had RAM issues. Memory Diagnostic tool said there was a RAM hardware issue, so I replace both sticks. Booted fine and ran problem free for maybe two days. It then displayed the BSOD back to back (to back), with various errors each time. Upon power up now, the screen remains black and there are no signs of life other than a slow blinking power button and caps lock key. Is there anything else I can try before I spend a fortune getting a pro to check it out?

Hi GGuthrie!


Welcome to community forums

 

 

What are the error messages that you are getting this time? Can you send a screenshot of it? And also, does the issue happens when the charger is unplugged or plugged in?

Have you tried those two memory sticks to other devices to check if it works?


Let us know.

No error messages now as it won't even turn on. A couple of them I recall seeing were IRQL_NOT_LESS_OR_EQUAL and UNEXPECTED_KERNEL_MODE_TRAP. I'd send pics but its completely black. I've tried with the charger plugged in an without it with the same result. I removed the RAM and tried it one stick at a time as well as the old ones with the same result. No RAM inserted produces a pattern of beeps and it then shuts off. Thanks for any help!
