Black screen F12 key has red light.

Need help. Did a backup like the system asked for. Shut my PC down but when I went to go in to check my emails it wouldn't start up .It just has a black screen and the F12 key stays red.

Took the battery out then replaced it and my laptop is back to normal. Such an easy fix.

Hello mabebabe,

I see that you were having start up problems with your HP computer.

Is the issue totally resolved? Thanks for posting an update of what worked for you!

Hi Manoj_pradeep,

I understand you are getting a f12 key with a red light on it. Resetting your computer forces the system to clear and reestablish the software connections. If you follow this document it will help resolve your issue. Start with a Hard reset.

Let me know how this goes.

Thanks

I have this same problem but when I resarted my laptop reported Boot Manager missing. The caps lock light flashes slowly twice before it pauses.
