The most of our time is spent working on the laptops that drain the battery over time. Without a battery, your Lenovo is fully useless. But, before it fully vanishes, we must attach it with a charger to complete the work. We have catered our technically refurbished team to recommend the steps for the inspection of the batteries in the PC. 

Lenovo Technical Support provides the hacks for checking the percentage 

#Trick Number 1: System diagnostics

1. Unplug the power cord.
2. Switch off your system.
3. Use the switch button to reboot the screen.
4. Move for the escape key quickly once your laptop charges up.
5. The start menu will be visible on the screen. Choose the system diagnostics. 
6. It will pop up the diagnosis and component tests. Choose the batteries link. 
7. Plug in the power cord and start the tests of power. 

#Trick Number 2: Be clever

1. Detach your batteries.
2. Run your system with the help of the AC Adapter.
3. In case it begins perfectly, you know it is a problem with the batteries and not the PC.
