I have a hp envy 4-1212tu. It's battery was gone for a month, with the ac adapter with no battery backup. Suddenly today, it wasn't turning on. The CAPS LOCK button was blinking and f12 (aeroplane mode button) was red. I went through some archives of ho community help, and sone youtube channels. Blown the vents several times to remove any dust, tried to turn on, didn't work.
Then I found in an archived hp community post that pressing escape key will take it to HP menu. I went there, started extensive hard disk check, it passed the initial smart check. While the extensive test was on for 5 minutes, I aborted the test and my laptop turned on.
I'm scared about the laptop not turning on again. I'm a University faculty and have to take online classes. Also taking it to a repair shop now is very risky due to Covid-19 situation here.
I want2know what could be the reason that my laptop wasn't turning on?
What did I do that it turned on afterwards?
