a. Disconnect the charger from the laptop, if connected.
b. Remove the main battery from the laptop.

c. Open the laptop and remove the coin cell CMOS battery from the motherboard. Remember the orientation of the battery for when you have to re-insert it, normally it is +ve on top. Here’s the ifixit [guide|28940] guide. I realize that this is not the problem but the guide is useful as it shows how to open the laptop so that the CMOS battery can be removed from the motherboard. Gently lever it out with a small screwdriver - don’t slip! When you have removed the battery, check its’ voltage. If it is <2.6V DC replace it. Usually it is a CR2032 non-rechargeable Lithium coin cell battery that is available most everywhere. The battery type number will be printed on the battery. They have a life span of~5-6 years

d. Press and hold the laptop’s Power button for 30 seconds and then release, to dissipate any residual charge in the motherboard. This action will reset the BIOS back to its’ default factory settings in case they were corrupted and preventing a normal start
e. Reinsert the CMOS battery (or replacement battery - see Step c. about orientation) and then reassemble the laptop.
f. When reassembled, reinsert the main battery and connect and switch on the charger.
Try to turn of the laptop. If it starts, there may be a message regarding the date and time is incorrect. This is normal as the BIOS has been reset. After the date/time has been corrected the message won’t show the next time that the laptop is started.
Check the charge status of the battery. If it is charging allow it to fully charge. If Win 10 is installed, create a [https://www.windowscentral.com/generate-battery-report-windows-10|Win10 battery report] to check the status of the battery to see if it needs replacing etc.
