This is a known problem with this type of computer. This is most likely due to a processor error, and we do not know of an easy way to fix this. I'll update this if I find a reliable way to fix the problem.

There is a button on your computer which turns the trackpad off, and you may have acciedntally pressed it. Here's a link to the troubleshooting page about this.

There are a few possible reasons for this, and here are some links to the troubleshooting page along with explanations: 1. Your charging port may be broken. This is most likely the case if your port looks damaged. 2. Your motherboard might have an error. Most likely, if this is the case, you won't be able to use your computer when it's plugged in, either. 3. Your battery might be broken. If your computer works fine on the charger, but the battery won't hold a charge, this is probably the case. Hope this helps!
