not charging my laptop

Solution

Most modern laptops limit charging in order to protect battery endurance. You know how in the old days, after a laptop was 2-3 years old, the battery would last only 15 minutes? That's what happens when you charge a battery to 100% or discharge it to 0% too often. The number of charge cycles the battery will last decreases if you do a lot of full charges or full discharges.

To protect against this, most modern laptops limit charging in some way. e.g. It will stop charging when it reaches 80%. Or it will charge to 100%, but won't charge it again until the charge drops...

Do the following steps and see if it helps.
First, run it only on battery for 10 minutes and see if it is discharging normally.
If it is, switch of everything and unplug the charger from the laptop.
Take the battery out.
Plug the charger to the laptop and the power supply and switch your laptop on.
If it switches on, your laptop is OK.
If it switches on, again turn it off, unplug, put the battery back and give it around 10 minutes charge and then switch it on. If it works normally for sometime and charges normally, your problem is solved.

To protect against this, most modern laptops limit charging in some way. e.g. It will stop charging when it reaches 80%. Or it will charge to 100%, but won't charge it again until the charge drops below 80%.

So try letting the battery discharge to below 50%, then charge it again. If it charges all the way, the "problem" was the battery protection system, and nothing to worry about.
