Question about HP Pavilion Ze4805us Notebook
I am trying to fix a laptop but I am puzzled. The laptop is a HP Pavilion ze4805US and the letter "f" keeps typing for no reason in word or anything... and no keys worked at all.
I replaced the keyboard but that did not fix the problem. 48$ :-(
The laptop ran for 20 mins eracticaly with the new keyboard then i turnd it off to goto lunch... then now it wont power on at all.
Any suggestions? Thanks.
Hi FRND,
Your Keypad is short with some another keys you need to open the Keypad by the bottom of the LCD screen lock ...
then open the F key on the Keypad... just clean by any brush and remove the all keys beside the F key... clean it properly....
here it goes your keypad is working .... properly :)
Best Luck...

This symptom appears without a keyboard installed. Upon further review if you look at the capacitors near the keyboard cable, they are probably blown. Try replacing the mushroomed capacitors and see if that helps.

If can open the Mother board carefully and wash it with Spirit or petrol nearby the Key board Connector should solve the problem.

This wont help. Not the cause.There are hundreds of complaints about this on the internet and is most likely a hardware electronics issue. Either the board is bad or the capacitors that control this chip are.

Yes, sounds like your system board is ka-put. (bad).

Mine type MMMMMMMMMMMMMMMM AT RANDOM ALL THE TIME CAN"T FIX
I have a HP Pavilion ze5730us. My system generates jjjjjjjjjjjjjj until I hold down the "a" key on the keyboard. As long as I hold down the "a" key, I can do anything normally (except type the letter "a"). I have ordered a new memory chip 512M (I can use the add'l memory anyway) and a replacement keyboard and hope that one of these will fix the problem. The problem started about six months ago as an intermittent problem. At that time I could stop the sporadic characters by pressing the "a" key once. A week ago my system would not boot up. Eventually I discovered that it would boot up as long as I hold down the "a" key. If either of these planned fixes work I'll post.
kepad not working at all
