Windows 10: Battery Report shows incorrect values

So today I was using my Acer Predator Helios 300 laptop when all of a sudden it turned off. When I turned it back on it was showing the update screen. So I let it update and after the battery showed as 63% whereas before it turned off it was 66%. I generated a Battery Report and it also showed negative values. The last time I had this problem was last year in December. To fix it I just charged it to 100% and then used it until it shut down. So what do I do now? Should I update the BIOS, even though I haven't changed any of the settings there? I attached the Battery Report below.NOTE: The charg

Battery report

Gabriela,

I have very precise records of when I swap over my batteries [because I run battery reports both before & after] and the moment of opening up the computer or changing the battery does not show up in my battery reports.
- My Battery report section Usage history - History of system usage on AC and battery goes all the way back to when the computer maker finished setting the computer up [and then posted it to me]. Your corresponding records seem to show the same.
- I know of no command to reset the parameters listed in a battery report.

The Start time entry you circled in red shows the time that the computer was turned on or awakened on battery power. There is no indication of anything dishonest being done. Windows re-starts that list whenever it feels like it. There is nothing significant in that entry at all. Just for example, my Battery report Start time entries are only showing for today but the computer was in use yesterday and earlier on battery.

Incorrect Battery Report, no estimate available

Hi,



Thank you for writing to Microsoft Community Forums.



I would like you to know that the battery estimate report is generated as per the sensors that are present within the laptop to sense the battery. It could be an issue with the sensor and that could be the reason you are receiving a false estimate.



I suggest you to try updating the battery drivers, generate a report and see if that makes any difference. Please follow the steps mentioned in the article

Update drivers in Windows 10 and update the
Microsoft ACPI-Compliant Control Method Battery driver. The ACPI driver is responsible for the power management and Plug and Play (PnP) device enumeration.



If the issue persists, I suggest you to get in touch with the laptop manufacturer and have a check with the battery and the battery sensor.

Empty values for capacities in the battery report, cycle count value is crazy, but the icon is right

Hello LouisMS,

One of the reasons why the battery report of your laptop doesn't show the correct information is that the battery drivers currently installed are not updated. For us to elaborate the issue further, kindly answer the questions listed below:

• Were there any changes on your laptop prior to experiencing this issue?
• What's the make and model of your laptop?

For initial troubleshooting, we recommend that you update the battery drivers of your laptop. Check this article on how to perform it:

Update drivers in Windows 10.

We're looking forward to your response.
