Aspire 7715z Keyboard problem

RichardL

My Aspire 7715z has keyboard problems. In some cases I do not get the expected character when entering the key but a combination of two chars. This happens primiarily with keys on the left side of the keyboard, see details below.

 

Earlier this week I replaced the keyboard with a brand new one expecting it would fix the issue. Unfortunately that's not the case and I still have exactly the same problem using the new keyboard.

 

Any clues what hardware of software components could cause this and how to fix it?

I tried adjuisting the windows 7 keyboard settings but that doesn't help.

 

w becomes ws         s  becomes ws

d becomes ed          e becomes ed

r becomes rg           g becomes rg

y becomes yh           h becomes yh

k becomes km         m becomes km

In addition combination of some keys like ALT-TAB is not working either.

I would try re-seating the ribbon connector a half-dozen or so times just to make sure the contacts on the motherboard are cleaned up a bit. Sometimes the sliding clips that secure the ribbon tightly to the connector break off resulting in strange behavior. In the latter case, a bit of tape can save the day.
