Thanks cottontop if anyone else posts I'll followup but I appreciate your assistance.

Done still five blinking blue lights.

How do you remove the RAM sticks? I'm at a cafe with a small screwdriver set and a lintfree cloth.

OK will try that.

I get 5 blinks when pressing the power button with the adapter and battery in. Without the battery nothing.

Power + F2 gets 5 blinks.

Mobile tech in another state reinstalled Windows 10 did not...

Yes it is connected to the AC adapter and to the wall outlet.

It is an asterisk

Thanks cottonball. It is an Acer E1-572-6870 laptop. I can't see the thumbs up icon from my phone but will glad to send kudos when the laptop is back in shape

Tried hard reset. Still getting single blinking light after several tries. What else can I try? How do I know if the battery is charging? Thanks
