Incorrect reading of memory stick capacity

Hi RS322767,

When did the issue start? Is the issue seen on the USB 3.0 port and the USB 2.0 ports on the left and right side? Are you using USB 2 or USB 3 devices? Does an external mouse work fine? Does an external HDD work fine? Are you able to read and write data to the USB drives? What is the size of the USB device you have connected and what is the capacity it is detecting? Does it detect the right capacity in Disk Management?

If the system was working fine earlier, then perform a system restore to restore the machine to an earlier point where it was working fine - http://bit.ly/1JEw2ov

Update the BIOS - http://dell.to/2fkDGBY- restart and check.

Check if it works fine in the built in admin account - http://bit.ly/1JoFhcw

Hi Rishi, I am actually having an issue with my AC adapter not being recognized, not any of the usb ports, but thanks anyway!
