HP Pavilion ze4805US Keyboard / Power on Problem

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.

    Mine type MMMMMMMMMMMMMMMM AT RANDOM ALL THE TIME CAN"T FIX

  • Chuck44 May 02, 2008

    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.

    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.

    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.

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...

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

My mother gave me a HP Pavilion ZE 4500. I push the on button not a thing happen. No flashing light, No sounds.


Hello.

The most common reasons are the power adapter/cord and power jack.

If you move/wiggle the power adapter at the point where it connects to the laptop, and the power goes off and on, the power jack is the problem.

The power jack is inside the laptop and either needs soldering or replacement.

If no change, the power adapter is probably faulty and needs replacement.

Hope this helps.

Key board controller not working


Try connecting an external USB keyboard.

If that does not work, then it's time to contact HP, and order a replacement motherboard, or to purchase a brand-new notebook, or, if the product is still under "warranty", to make a warranty claim, to get HP to fix it, at their cost.

Video problem. Pavilion ZE4805US laptop


Most likely it is either a bad lcd inverter, due to the fact that you have clear picture on an external monitor. The inverter reduces the voltage coming from the motherboard to a lower level in order to power the lcd and the backlight. If this goes bad then you either get a picture randomly, a dim picture, or no picture on the lcd.

Hp pavilion dv1000 laptop pc keyboard not working properly.


Does this computer KB work alright in SAFE mode? If it does then drivers and/or viruses are the problem. If it doesn't work in SAFE mode then it could be drivers and or keyboard. Now try booting into BIOS. At the date prompt you usually can type any keyboard letter. If the keyboard works here, then you definately have driver/virus issues. If not replace the keyboard.
