    I just installed a mother board in E1505 and new Seagate hard drive Loaded Win 8.1. not happy with that but had to with the hard drive, and the touch pad does not work. I removed the keyboard to check the connection and it seems to fine. Any ideas

      Check to see if the BIOs on the motherboard needs to be updated. You can find the BIOs update at support.dell.com . If that doesn’t fix it, check the other cable connection on the bottom of the touchpad. It may have been knocked loose.
