Is this for recalibrating laptop battery? Do I need to switch off the laptop?

Yep-it worked exactly as suggested. Sharp end of a small safety pin and bobs your uncle.

Thanks again. Was worried that it could be something worse.

Ok, it works perfectly..., thank you to your suggest.

My Acer Aspire ES1-512-C08J, did not accept anythink from keyboard to input password at start of windows 10, but in Bios setup did it works.

No solutions to change keyboard, or reset bios to default configuration, but only when i pushed in the pinhole reset switch battery on back laptop, while laptop was on, and it immediatly drops down switch off, and when i restart laptop from normal push button power on, all works another time ok.....

Sorry for my bad english...

The battery cell may have some unbalance. This i planned obsolescence. Manufacturer omit a proper balance circuit in the battery so over time the unbalance get bigger en the effective useable capacity will be reduced dramatically by the safety circuitry in the battery. This does not mean the cells are bad. You need to balance the cells, but this requires opening the battery, soldering a balance connector to the individual cells and using a balance charger. No manufacturer will tell you this nor will they admit it. I just reconditioned my battery laptop myself and it's still going strong after 3 years.

Holy wow. The actual bloody service manual for 481PT makes no mention of this pinhole. I thought I shorted the battery and almost ended up ordering a new one (and a new MB for good measure). So yeah, guys, if your Acer M5 says it has a battery but refuses to work without AC, putting a stupid pin in the stupid hole while on AC power for 4 seconds solves the problem. For me, at least.

It didn't work for me. It comes to a screen where it says "automatic repair, your pc did not start correctly". I've restarted it and it goes to a blank screen and the fan keeps kicking on, I've tried to push and hold the reset button and it didn't work. I've pulled the battery out and it didn't work. Help.

Did not work for me. When I reconnected the A/C power and pressed the power button, one of the blue lights on the front flashed 5 times and quit. No sign of life.

Did not work for me. My wife’s Aspire V simply died. When I reconnect the A/C power and press the power button, one of the blue lights on the front flashes 5 times and stops. No sign of life.

Hi - please describe how the laptop should be at the time when you hit the rest button:

- should it be plugged in and connected to power? or plug out?

- should the computer be powered on or off?
