Dell 7737 BIOS v14 has a keyboard bug where random keyboard keys stop working till the AC is disconnected and the battery removed or drained.

I have a Dell 7737 laptop and from time to time it develops a firmware glitch where random keys stop working for both BIOS Setup and Operating Systems. After such thing happens neither shutdown (Full shutdown / Fast Boot disabled) nor restart get the keyboard back to a normal state. At this point the only workarround is to disconnect the AC power cord and then either drain the battery or physically remove it.

This laptop's battery cover is not designed for daily removal and it is starting to get loose because of this BIOS bug.

I am running BIOS version A14 but this bug was present since I purchased the laptop with BIOS version A07. Sometimes I cannot even type my password because the random keys that stop working match those it uses.

Please Dell could you provide a BIOS hotfix for this annoying issue?
