HP pavilion won't stay on

[Reneeann]

Unable to stay on. Light comes on but won't boot up. Have tried F11 repeatedly pushing. Still not staying on.  Power key comes on and then goes off and then goes on and then off.. will not remain on.

 Screen stays black when on. Ran ok yesterday.

You may try first turning on the PC using another outlet, changing the charger, doing a Hard reset and checking the RAM.

Alternatively, unplug the system, remove or disconnect the battery and hold the power button for 30 sec.  Remove and reinstall the memory module(s) -- then try powering up.  If the same error arises, try one module at a time in each socket until you isolate the bad module or the bad socket(replace the mainboard in that case).

Otherwise you can just check out the post "Fix My (Windows 10) Laptop/Computer Won’t Turn On" for a solution.
