Acer Aspire 5 A515-54G shutdown on battery power it doesn't turn off.

Streetwise

Hi,

I have a one year old Acer Aspire 5 (Aspire A515-54G).
Recently, when I only use it on battery, it suddenly shuts off.
Not immediately but at random times.
Restart only works if I connect it to the mains.
The battery is charged to 100% on the mains, so no problem with that.

When I'm in bios, with battery power, it doesn't turn off.

I've tried  reinstalled the system, reset battery, updated drivers, nothing helped.


Any idea ?

With laptop plugged in go to the elevated command prompt.  Enter 'powercfg /batteryreport'. Then return to the desktop. Open file explorer. Then search for' battery-report.html' in the c:\windows\system32\ sub-folder. Double-click to open it in the browser. Post screenshot of the first part of the report if possible that compares design full charge capacity with its remaining full charge capacity.

Battery & charger seem to be OK. Open Device Manager. Click batteries folder. Right click and uninstall every driver you find in the folder. Exit Device Manager and shut down Windows normally without reinstalling anything.

Wait for battery charge LED to turn steady blue again. Then turn machine on and let Windows automatically re-install fresh copies of the battery and charger drivers.

Then disconnect the charger again. Machine should now stay on until you get a low battery warning below 10%.

JackE, 

This solution did not work. What struck me was that the ACPI driver had a date of 2006!

When I plugged it back in to the battery, it turned off right away.
After I connected it back to the mains and pressed the power button, it automatically turned on 3 times and off 3 times.
I was only able to log in again the fourth time.

The WinXP era driver is correct. 

BUT you also said

>>>When I plugged it back in to the battery, it turned off right away.>>>

What do you mean by this? What did you plug into the battery? Did you have the bottom off when trying to do this?????

Ok again, this is what I did:


On mains: 

Open Device Manager.
Click batteries folder.
Uninstalled 2 drivers in the folder.
Battery is currently 100%
Exit Device Manager and shut down Windows normally without reinstalling anything. 
Wait for battery charge LED to turn steady blue.

Disconnected the charger.

On battery power: 
Shutdown at 100 % battery power. 

Connected charger again on mains. 
Pressed the power button.
Laptop automatically turned on 3 times and off 3 times.
After the fourth boot I was able to log in again.

>>>Wait for battery charge LED to turn steady blue.>>>Disconnected the charger>>>>

Was Windows booted when you disconnected the charger? Or did you disconnect the charger before booting into Windows?

Streetwise

I disconnected the charger before booting into Windows.

JackE

No. Sorry. Do it again but do NOT disconnect the charger until after Windows has loaded andautomatically detected the charger and reloaded fresh copies of its drivers.

Turn machine off. Wait for battery charge LED to turn steady blue again. (Don't disconnect the charger yet) Then turn machine on and let Windows automatically re-install fresh copies of the battery and charger drivers. Then disconnect the charger again. Machine should now stay on until you get a low battery warning below 10%.

I did the procedure again your way.
This time I did not disconnect the charger.
Makes no difference, same result.

Is it so effective?

Have you tried removing the bottom cover yet to temporarily disconnect the battery from the mainboard?

Streetwise

No, for now I will connect it to the mains. I think it must have something to do with software or drivers, after all, this problem does not occur in the bios   on the battery power. Then the battery drains to 5%.

JackE

The BIOS uses only a small fraction of the power that's needed to load Windows and its graphics. While your battery energy (watt-hr) capacity seems OK, it still may not be able to deliver the power (watts) needed to run Windows due to a high resistance either in the battery itself or its connection to the mainboard. The battery and charger drivers were automatically refreshed from a disk archive when you uninstalled them from Device Manager and restarted Windows. This points to some kind of hardware. I suggest removing the bottom cover and at least reseating the mainboard battery connector a few times to help clean its contacts.

I'm going to try, but not this year because I'm very busy at the moment. I will report to you early next year whether it was successful.

OK. Jack E/NJ

Changed my mind this morning.
Saw on the internet that the bottom cover of the laptop was easy to remove.
Reseated the mainboard battery connector as you suggested.
After that I started some yoyube movies and some other applications to drain the battery.

This afternoon I saw that the laptop was off.
Then connected to the mains and logged in.
The battery status was 1%.

So you were right!

Have one more question for you . 
I want to make my RAM bigger, any idea how much RAM I can install at most. 
Now I probably have 4 gig (see photo).

You can swap the 4GB DDR4 sodimm module with up a 16GB DDR4 sodimm module 2666MHz or higher

Thanks man for all your help!
