My touchpad is not working after upgrading to Windows 8 Professional. I have a Lenovo Ultrabook u300s, the
touchpad i believe is Cypress Trackpad. The mouse cursor simply doesnt move but I notice if I click the button it will response. I have installed the latest driver from manufacturer support website. The only way
i can get it work is to remove the driver, but the standard drivers by Windows doesn't have the palm detection. Notice also the key button (F6) to disable the touchpad doesnt work anymore

Hi
I just had this problem with my Packard bell windows 8 laptop, i tried different ways to sort it and nothing worked. i went onto my laptop settings and i had locked my touch pad without realizing and now it works fine, might be worth checking. hope this helps.
This was so simple to fix. Anyone who is having this problem, just look at your function buttons on your laptop. If yours is anything like mine, then you have to press fn before pressing f2. If so, then, look at the keys and there is one with a little image of a mouse/no-mouse. On mine, it is key f5. When pressed without the fn button it locks the mousepad. With that said, I inadvertently locked my mouse after trying to press f5 to refresh a webpage. Hit it just once, and the lock comes off.
That is a seriously pesky feature...
Fn-F7 on Acer Aspire restores touchpad functionality (hold Fn down and press F7 key)
thank you very much
I had this problem with a Gateway I3 4 gig. I found that when the touchpad locked up Taskmanager was reporting that the HardDrive was running at 100 percent. If you phrase a search using "hard drive 100 percent", you will find that this is a problem with 8 also. System (more so the kernal) is seeming to cause this.
I believe I have fixed it by changing the settings for page fault.
Search for "manage computer" you can find the old "system properties" window (why is this stuff so hard to find in 8?) Under Advanced is the "performance settings" button. Under that button is the "virtual memory Change" button. Finally uncheck the manage paging file for all drives (my laptop only has one drive one paging file) select system managed size. Reboot.
I have been running for 2 days now and everything is faster - there have been no freezes.
