Keyboard locked up in Advanced Options Menu

To remove the keyboard-- turn the computer over & look for 2 screw holes with a K next to them (keyboard) -remove them- Flip it right side up - there are spring loaded tabs along the top of the keboard- press each one in twards the screen while lifting gently on the keyboard & it will lift out- the cable has a slide release on the motherboard- slide the 2 side tabs out to release it.
good luck- (keyboards are available on ebay very cheap)

Good morning perk!
From what you are telling us, it sounds like there is a key on the keyboard that s stuck, or thinks that it is stuck.
The first step is to check the keyboard to verify that nothing is stuck down to carefully clean the keyboard. The second step is to operate each and every key on the keyboard and make sure that each one feels like it is operating correctly. The third step is to disconnect the keyboard and power up, if possible.
Please try these things and get back to me with the results and any questions.
Thanks, and have an excellent day!
