If there is a yellow exclamation icon next to your keyboard icon, then you need to re-download the necessary drivers. You can do this by going into the Device manager. If the problem is with all the keys, then one of the first things you can check for are faulty keyboard drivers. It might sound and look odd, but it could do the trick. For starters, you can simply turn the laptop upside down and shake lightly to see if that helps dislodge any dirt or dust. In the case of the some keys not working, it could simply be because of some sort of obstruction.
Your entire keyboard might stop functioning or if you’re lucky, just a few keys. Laptop keys generally take a beating so you can expect it to be one of the first things to pose an issue. If you see some unusual software that shouldn’t be here or ones you don’t want to run in the background, just click on them and then turn off the ‘Allow this app to run in the background’ option. This will give you a list of apps that are consuming battery. Go to ‘Battery saver’ mode then select ‘Battery use’. You can check that by going into the Windows ‘Settings’ and then ‘System’. If the battery drains quicker than it should, then it’s also worth looking at what software are running in the background. With the battery back in the laptop now, and it not getting charged, you might need to get a new laptop charger. Try using other wall plug points just to be sure. If the laptop doesn’t turn on with the charger connected and the battery removed, then it could be a charger problem. You can inquire with the brand’s service center. In that case, you’ll need to buy a new battery for your specific laptop model. If the laptop still switches on and works fine, then it means your battery has issues. First you can find out if the battery has gone bad by detaching it from the laptop and then plugging the charger to the laptop.
In almost all the cases, it’s the battery that is causing the problem. This is one of the most common laptop problems.
