up and down keys are not working

[qtvip]

Hello,

My up and down keys are not working (only up and down not all arrow keys) after I cleaned up my keyboard. I also noticed that the phone key (hang up) has now a red light that disappear after I start typing.

I did everything: Bios update, formatting...

Keyboard test on bios shows that these keys are not working. Should I replace the keyboard now?

What did you use to clean the keyboard? You should NEVER use wipes of any kind but only compressed air from the cans you buy in PC stores or office supply stores.

Here's some troubleshooting steps you can try regarding the keyboard issue: http://support.hp.com/us-en/document/c03738933

If the laptop keyboard simply does not work, then you will have to plug in an external keyboard and see if you can run the tests using that.

If you are experienced at laptop repairs, you can often replace a keyboard for $25 for a new one and a half-hours work -- but this is only true for on older HP laptops where the keyboard is held on with a few screws.

But with the newer laptops, there is a serious risk of breaking fragile connectors and cables doing this because you have to disassemble the whole laptop. So. I do not recommend it. Instead, I would recommend you hunting down a local laptop repair place to have THEM replace the keyboard. Sometimes, on some models, you have to replace the entire top surface of the laptop, not just the keyboard. So you should get an estimate of what is involved before you have the work done.

Thanks for your reply. Unfortunately I used water wipes. it seems these keys are no longer working. I also tried your troubleshooting solution but didn't work.
