Laptop shutsdown at 25% charge

I've been using my laptop for less than a year and just recently noticed that my laptop would shut down at around 25% charge. It would not turn back on unless I connect the charger in. It is a Lithium-a battery.

Not surprising since laptop batteries lose their ability to hold a charge over time and yours might simply be dropping suddenly from 25% to something too low to keep the laptop powered up.

You can check the battery to some extent using Powershell built into Windows 10. as follows:
1) Press Windows key + X
2) Click Powershell in the menu
3) Type powercfg /batteryreport

This will generate a report and if you scroll down, you will see Design Capacity and Full Charge Capacity ratings. If the Full Charge Capacity is less than 50% of the Design Capacity, it is faulty and needs to be replaced.

Also note the figure alongside the "Cycle Count". This tells how many times the battery has been fully recharged. A typical battery can handle around 500 charge cycles, but some will fail sooner than that.
