ES1-411 - Battery is causing keyboard and mouse to stop working

grahame33

Hello!

We have several Acer ES1-411 laptops within the school. They've been in use for two, maybe three years (prior to my employment) and we have a few that are now experiencing hardware issues.

The trackpad or keyboard aren't working on some of them, others not charging the battery that is plugged in (but, recognising there is a battery in). For two of them, I entered the BIOS and changed the trackpad setting from Advanced to Basic which resolved the issue at first but, I changed the battery from one (where the keyboard wasn't working) as it wasn't registering the battery and as soon as I did that, the keyboard stopped working. 

I left the battery out of the one where the keyboard wasn't working, plugged it into the mains and the keyboard worked! 

In the process, two of the batteries are knackered but, the remaining "working" one was put into a laptop this morning (just to test, no keyboard OR trackpad issues) and now the mouse doesn't work!! 


Is there any explanation for this? I'd like it if this was sorted as the laptops are solid otherwise.

Thank you in advance.

The batteries are at least 5 years old due to the likely mfg dates for this model. Probably on a case label or inferred from the BIOS firmware version.  Hard to tell what might happen to input devices if mAhr or mWhr capacities are less than 50% of the original design capacities and working voltages are compromised due to potential internal shorts.  On the problem machines, 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. Jack E/NJ

I tried running the battery report but "An unexpected error (0x10d2) has occured: The library, drive or media pool is empty" - would this be because it's not actually registering?

I ran powercfg -energy -output energyreport.html instead and "10 errors, 8 warnings and 19 informational" came up. I can upload that, if that will assist at all?

Did you run powercfg from the elevated/administrator command prompt? Jack E/NJ

I believe so. The only account on the laptop is the Administrator user and I'm selecting "Run as Administrator" for the command prompt. Is there something else that I need to do?

Some folks have reported that replacing the battery resolved that particular powercfg error message issue because Windows can no longer detect the battery's internal charge controller. I'd guess it wouldn't affect HIDs unless the battery also has an internal short. $20 for new replacement batteries from Amazon. ACER Part # KT.00403.012 or Sanyo, Panasonic or other mfr part no.
