Frequently Asked Questions
Why is my laptop trackpad hard to press?
In most modern slim laptops, the battery is located directly beneath the trackpad. When lithium polymer cells degrade and swell, they push upward against the trackpad. This is an urgent safety issue and the battery must be replaced promptly.
