Forced to Reset Battery Constantly

So I have an ACER Aspire laptop that is currently running a fresh install of Linux Mint, but has had this problem with Windows as well. 

 

After leaving plunged in for an extended period of time (over night) AND/OR just leaving it sit there for an extended it will require that the battery reset button be pressed with a paper clip. 

 

The battery remains at full charge though this process. 

 

I have tested the power adapter with a volt meter and I'm getting 41V which is way higher than the 19V on the side of the adapter. Is this part of the issue?

 

Thanks,

JK29

It depends on how you measured the voltage, it may be at 19V when under a load but could be much higher without a load.  Also, you didn't say whether this is a DC voltage or AC.

I had the volt meter on DC.

Probably doesn't have anything to do with the charger.

 

I was wondering if yall knew of another reason for a laptop forcing you to hit the battery reset frequently.

The 41V reported in #1 got me thinking and I went and checked the open circuit output voltages on three OEM laptop chargers - different makes, Sony, Toshiba and Fujitsu - and the voltages I got were 19.4V, 19.9V and 19.2V. Since the rated voltages under load are 19V (2) and 19.5V (1) this is about what I would expect and I would not be unhappy with any OC voltage up to say 21V.

 

I would re-check that voltage making sure that the meter was set to DC volts and on a range going up to about 200V, different meters have different ranges. If this confirms the open circuit output is 41V, or thereabouts, I would be very doubtful about the charger and I think the best thing would be to replace it or at least try another.

I am going to be away on holiday until the 13th May. While I expect to have internet access my time on-line may well be limited and PMs may not be replied to as quickly as normal.

Yep it was on DC and the range was 50. I also tested it with the range set at 250 to confirm. 

I then plugged it into the laptop and tested the power plug, which is also getting 41V though it. 

It's defiantly charging the battery though.

 

 

 

Today my wife was using the laptop on battery. Once it got low she plugged it in. Soon after it just shut off. Brought it home, pressed the battery reset button with a paper clip, and it started right back up.

What are the specs on the adapter.  They all have a tag or stamping of the rating, voltage and current but the AC DC designator is just a pair of straight lines for DC and a straight line a sine paireed with a sine wave for AC. The meter being set to the wrong AC/DC will display some strange readings, mostly based on the sampling proccess of the meter itself.

Are you referring to resetting the CMOS battery?

 

Is the time and date on this computer correct?

 

What is the model of this Acer Aspire?

 

Please post the error message you are receiving.


Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

No error messages, just shut down. Time and date are right. 

 

I'm referring to using a paper clip though a hole on the bottom of the laptop to reset the battery.
