Hello my name is***** do not rate until we are finished. I look forward to assisting and am very sorry to hear that you are having this problem. I want to warn you that it is possible you will need to replace a part in order to fix this. There are a few different things that can cause this and a couple different parts so we would need to troubleshoot to find out for sure. Is this happening with both the built in keyboard and external usb keyboards?
Ok let me know the results when you can.
Have you tried installing the driver from here?
Click drivers & updates, then on the left click on keyboard it will show all keyboard related downloads after that on the right.
Ok well another option would be forcing it to reinstall.
To do that click on start and type device manager into the search.
Expand the keyboards section and right click on your keyboard.
Click on uninstall it the right click menu, then restart the computer.
It will automatically reinstall itself when restarted.
If this did not work, please come back and let me know what happened when you tried it by clicking on reply to expert so we can continue.If it did work, please don’t forget to leave a positive rating - it is greatly appreciated.
I apologize but I need to opt out and open this to all experts.
The keyboard is physically broken. the keys themselves are not making good contact when you press them. You might be able to get it working by using compressed air or physically popping off the keys and cleaning underneath each one. But its a real pain and may not work.
replacement keyboards are widely available and cost about $20
here is one of them but as there are several p775 models make sure that you get the right one.
You can watch this video and see if you want to replace it yourself. Its about 3 screws and 2 cables but you have to remove the battery and hard drive and pry it out a little bit.
a repair shop would probably charge about 50 bucks including the keyboard itself
honestly i cant think of anything that would do that software wise. If the driver is bad it would not put up the keys at all or put up the wrong letters. It is a hardware problem somewhere.
There really wouldn't be much else I can suggest. It could be the cable or the connection or the mother board. There isn't anything else.
I would say take it to a repair shop. Not so much because they can do it better than you but because they would have to guarantee they fix it and have spare parts they can swap in and out till they find the bad one
There is only one other thing that i can think of. Its possible that another program running in the background is conflicting with it. Though i would think it should affect the external keyboard as well.
can you start the computer in safe mode and see if the keyboard has the same issue ?
No I am sorry to me that just confirms that it is a hardware issue. It might be the motherboard but I wouldn't even rule out that the new keyboard has the same defect. It might be reconditioned and it could be a common problem with the design. That's why I say give it to a repair shop where they can test it in another computer
Have you looked for bios updates for the computer. It doesn't seem likely that they would have or need one that affects something as simple as the keyboard but stranger things have happened
