I was forced to as one laptop would freeze and when it did work, it could not recognize USB ports due to lack of power.
On laptop #2, it was the battery that seemed to be growing. I have heard of swollen batteries and decided to get a new battery.
So fix it or loose it!
Easily. The first check is always the wires...clearly
Laptop #2 was swollen and all I needed was a coin to open and replace the battery.
BOTH LAPTOPS ARE HAPPILY WORKING.
Try it yourself. You might learn something! You can always call in an expert and get your problem fixed...
