Laptop keyboard does not work after sleep and touchpad  

A couple days ago, my keyboard and touchpad mouse stopped working. I thought it was a hardware issue and ordered a replacement keyboard. As for the touchpad, I'm just using a wireless mouse. I replaced the keyboard a couple days later with the new one, and when I turned on my laptop, it works again, but when I put my laptop to sleep and wake it up, I hit enter, and then it stops working. I cannot type anything until I restart my computer. I figured it has to do something with the drivers, but I'm not too sure. Here is my computer specs:

Product: HP Pavilion dv9700
Model: dv9925nr
Windows 7 home premium 64bit

I've gone to the HP website to get the drivers, but they do not support windows 7 for my computer.

try changing the power plan, as you said when it goes to sleep, it stops working. Ty changing it to high performance.
