Installed new battery, will not power on if unplugged.

After what felt like a decade, my laptop battery finally died. I bought a new battery, was hard to find, but seemed decent (link below). I installed the battery, just like I have done to every piece of hardware I have ever purchased, but my laptop would not turn on. The laptop turns on when plugged in with the charger, but not while on battery. Going to try charging it overnight and trying in the morning, but I am not hopeful. Any guesses on if my laptop is just busted and it is time for a new one?

According to Acer Care Center, battery health is good, I don't know if it's reliable or not though.

The first picture is the battery installed and the laptop locked.

The second picture is the battery installed and the laptop unlocked. Weirdly, the hover on the battery icon in the bottom right would not show.

My laptop is an Acer Aspire A515-54-51DJ.

Hi @clootbooters24

Does the laptop stay on if you start it on the charger and then once in Windows etc, did you disconnect the charger from the laptop, to see if it works on the battery only, you never mentioned that it did/didn't?

Try uninstalling the Microsoft ACPI Compliant Control Method battery drivers in Device Manager > Battery, and then when they have been uninstalled, close all open windows and restart the laptop in the normal manner.

During the following startup, Windows will reinstall the drivers. Check if the battery shows that it is charging etc. If it does allow it to fully charge (if necessary) and then check if it now works OK

Hi @jayeff,

I did uninstall both the charging and battery drivers last night and then rebooted. I left it overnight charging and right now it is surprisingly running off of battery. It still shows that it is 100%, but the hover does not work. The orange light on the side of the laptop is blinking, but IIRC that always has done that. I don't think the battery is correctly showing percentages and such because on the lock screen it still shows an empty battery like in my first photo.

OK at least now it's working on the battery only which I assume from your initial question, it didn't do before.

Create a battery report and check the design capacity value against the full charge capacity value plus other statistics.

This will tell you if the battery is communicating OK with the BIOS

Correct, it did not boot at all on battery, but now is. In the battery report, I get the following information in the "Installed Batteries" section:

Installed batteries

Information about each currently installed battery

BATTERY 1

NAME UNKNOWN

MANUFACTURER UNKNOWN

SERIAL NUMBER -

CHEMISTRY LION

DESIGN CAPACITY -

FULL CHARGE CAPACITY -

CYCLE COUNT -

Based on that information, it seems the BIOS doesn't even know anything except the fact its a LiON battery.

Not good that it's not talking to the battery. That's what the drivers help to do.

Perhaps try a full power refresh just in case it's a corrupted BIOS. Turn off the laptop, disconnect the charger (if connected), disconnect the main battery cable from the motherboard, (just disconnect it , you don''t have to remove it), disconnect the RTC coin cell battery from the motherboard (here's a video battery can be seen 0:16 seconds in, right hand side). Then press and hold the power button for a full 30 seconds and release.

Reconnect the RTC battery, main battery, reassemble the laptop connect the charger and turn on and check. There may be a message that date and time are wrong, this is normal, correct it and it won't appear again. This is due to BIOS being reset back to factory default.

if still no good, do you still have the old battery?

Is so, check what model number is on the old battery and compare it to the new and see if there the same.

If they are then it's looking a faulty new battery

@jayeff

Tried the power reset, no luck. I even went and bought a new charger to see if it helped. The battery has to be providing some power because the lights on the side indicating charging and such are blinking. I may try a different kind of battery, since the board obviously isn't fried. The model for the battery I got from the original, sadly don't have it any more though.
