Re: XPS 8500 lagging

Hi Metalion_SOS,

I’d suggest that you follow the steps mentioned below and check for issue resolution.

1. Switch off the computer.
2. Disconnect the power cable from the wall.
3. Press and hold down the power button for 15 seconds.
4. Then connect back all the peripherals and check if the touch screen is working.

Secondly, I would advise that you refresh the drivers for the mouse by going into the device manager. Please follow the steps mentioned below.

1. Open the charms bar by moving the mouse to right top corner of the screen and in the search box, type ‘Device Manager’, and then, in the list of results, click ‘Device Manager’.
2. When the device manager pops up, in the list please check for ‘Mice and other pointing device’.
3. Please click on the arrow mark beside ‘Mice and other pointing device’.
4. Right click on the mouse device and select Uninstall.
5. Restart the computer and check for issue resolution.

 Also, you can restore the BIOS to defaults and check for issue resolution.

Please let me know if this helps.
