Question How to make my Acer Aspire ES1-523 recognize a new battery?

[Beachhead1985]

I always press the battery reset switch when the laptop is powered off. Never when Windows is running.

Another thought. Do you run Windows with Fast Start enabled? If so, try disabling it. Shut down the laptop and press the battery reset button. Windows will take slightly longer to restart, because it's not pulling the most recent system configuration from hiberfil.sys. It might result in Windows finding the new battery.

I much preferred the old laptops where you pressed a couple of tabs to release the battery pack, which was filled with replaceable 18650 cells. These days, laptop manufacturers seem to think we all want slim laptops.

I bought an old Lenovo X250 Thinkpad recently (with a Windows 8 sticker) and was surprised to find it had two batteries. An old style rear-mounted lump and a non-working 45N1111 flat battery inside. I bought a replacement third party battery for $30 and was pleased when it worked without fuss. The official Lenovo battery was $130. I just hope the cheap battery doesn't catch fire!

Prior to buying a new 45N1111, I unplugged the suspect battery and measured its voltage which was just over 10V DC. The voltage quoted in the spec. is 11.4V so it wasn't completely dead.

I tried this trick to reset the ACPI driver, but it didn't restore operation, so I bought a new battery.

Sorry, that wasn't what I was implying, but the only picture I could find of an Acer battery reset switch showed what repair shops encounter, when customers bring their laptops in for repair.

I shut the screen/lid, before I flipped it over to hit the button. But I don't know if that counts as being "off". Tried it again with a full shut down and same deal.

It just kills me that it simultaneously shows the battery at 100% and doesn't recognize the battery.

I'm not sure what fast start is, but this thing takes so long to start after it's shut off from power (which I guess is what the button does?) that it can't be turned on.

Hmmmm...Trying the APCI thing and *right now*, after disabling and enabling the device, it is back to showing 255% battery power...lets try it with an un-plug...Holy cow... it didn't die! Okay, trying a restart now to see if that changes things. When I first put in the new battery, it showed something similar, but then it died on me, so lets give a try like this...

Huh. Okay, yeah; it reset back to not recognizing the battery on restart.

I shut the screen/lid, before I flipped it over to hit the button. But I don't know if that counts as being "off".

Closing the lid could do one of three things, depending on how it's been setup:-

1). Laptop enters Sleep Mode
2). Laptop enters Hibernation
3). Windows shuts down

You'll have to check Power Options to see what closing the lid does. There are settings for when the laptop is connected to the mains charger and another set of options when the laptop is running from battery.

I'm not sure what fast start is, but this thing takes so long to start after it's shut off from power (which I guess is what the button does?) that it can't be turned on.

If you check the link I sent last time it should provide more details about Fast Start. As I said earlier, if Fast Start is enabled, when you shut down the computer (by pressing the power button), Windows saves the current configuration to the Hibernation file hiberfil.sys.

The next time you switch on the laptop (by pressing the power button) if Fast Start is enabled, Windows loads the status preserved in hiberfil and starts up more quickly. The down side of this for my proposed test is Windows might ignore any changes you've made to the hardware/software and load the previous status without checking things more thoroughly.

This is only a theory, but making Windows start from scratch, as opposed to restoring from hiberfil, might wake up the recalcitrant battery. It's a pretty forlorn hope, but worth a shot. There are many other people out there with the same problem if you Google "battery not recognised by Windows".

You can easily check if Fast Start is enabled by following the guide I linked. It does make a difference on an old laptop, but generally only a few seconds. It depends on how many background processes and programs are loaded at startup. Check the Startup group in Task Manager and disable anything that's not essential. It can shave 10 to 20 seconds off load times.

Tried the fast startup thing; it WAS on and now it's off. No change though.

The Battery-Manager still needs to be turned off, then on to see the battery with each startup.

Something else I noticed: even when it is worked from the battery, as now; the battery light blinks orange.
