HP laptop possibly dead??

[learninmypc]

The battery is not removable. It was working fine one day, I shut it off , several hours later I pushed power on button & nothing. I've tried removing AC power cord & pushing power on button for several seconds, still nothing. Its about 4 years old but not used much. Any ideas, thanks in advance

Happy to say I did this >> To revive a dead HP laptop, start by performing a hard reset: unplug all external peripherals, disconnect the charging cable, and hold down the power button for 15 to 30 seconds to clear residual power......then a waited a few moments, pushed the power on button & a few seconds later it came back to lifeNow I hope it gives me a few more years

NOT having related problems with my ACER laptop, battery is NOT removable, how do I do same as above with it??

It's the same idea on the Acer. Shut it down, unplug the charger and any USB devices or SD cards, then hold the power button for about 30 seconds and release it. Wait a minute, plug the charger back in and press power normally. Some Acer models also have a tiny pinhole on the underside for resetting the embedded battery, so check the bottom of yours or the manual for your exact model, and use a straightened paperclip on it if it has one.

Ok, I inspected the entire laptop & see no tiny hole to do such. Also, I did as you suggested & it powered up as normal. Thank you

Since your laptop has a non-removable battery and has been sitting unused for periods over its 4-year lifespan, the most likely culprit is a deeply discharged or "frozen" battery state, a tripped internal safety circuit, or a failed power adapter.
When a lithium-ion battery sits unused, it slowly discharges. If it drops below a critical voltage threshold, its internal protection circuit cuts off all power to prevent damage, causing the laptop to act completely dead—even when you plug the charger in.
