One thing we must understand is that the battery of a laptop does not store charge forever. The battery will drain even if the laptop is shut down.
But this drainage will be so minimal that we don’t feel it unless we keep the laptop shut down for a long period of time. Some time one or more software is running during sleep mode or for some reason the CPU is getting hot, and the fan is always on to try to cool it off.
Check Closing the Lid Settings
To check this, follow the steps below:
- Go to Run –> powercfg.cpl
- From the left-hand menu, click on “Choose what closing the lid does“.
- Make sure you have selected Sleep or Hibernate under “When I close lid” option for both On battery and Plugged in.
2. Disable fast startup
Fast Startup is a feature of Windows 10 which controls the behavior of Windows 10 shut down and startup processes. Fast Startup enables Windows 10 to reload necessary components of the Operating System while keeping others in the memory resulting in faster boot times.
One caveat of Fast Startup feature is that its functionality can, sometimes, go weirdly wrong. For example, the user may want to shut down the system but the Fast Startup feature may restart the system instead. So the user may close the laptop lid thinking that the laptop has been shut down. The laptop, instead, would restart and keep on running with lid closed and would turn off when the battery dies completely.
If you encounter this type of situation, you should, probably, disable fast startup. Here’s how to do it:
- Go to Run –> powercfg.cpl
- From the left-hand menu, choose “Choose what the power buttons do”.
- Click on “Change settings that are currently unavailable”.
- Uncheck “Turn on fast startup (recommended)” under Shutdown settings.
3. Replace the faulty battery
f the above solutions don’t work for you, most probably, it is a hardware issue rather than the software one. This means you should check the health of your battery. To check the health of your laptop battery in Windows 10, follow the steps below:
Go to Run –> powercfg /batteryreport
This will generate your laptop battery health report. The default location of the generated report is C:\Windows\System32\battery-report.html. You can open this report in a browser. This report will tell you the designed capacity of your battery and the full charge capacity as well. If there is a lot of difference between the two, it is time to replace your battery.
This command can also tell you which programs keep on running during sleep mode. Just run the following command and you’ll get all the information about your laptop sleep mode:
Go to Run –> powercfg /sleepstudy
There may be other solutions to this laptop battery draining fast issue but I have listed down the most common solutions which, hopefully, will be beneficial for your case. In case, you are not able to fix your issue, please let us know in the comments below and we’ll investigate the issue further.
