Unlock computer keyboard

Plug in an external Desktop USB keyboard to test. If keys work, use that external keyboard, to go to control panel and check/adjust some keyboard parameters. Some virus change some of those parameters to "disable" your keyboard.

Otherwise order a replacement laptop keyboard from HP spares/

Hp laptop only half a screen

Hook a spare monitor to the video output, if okay! the LCD panel is defective and will need to be replaced. If spare shows no change! it means the video graphics card is bad and normally built into the motherboard.

My power cord seems to not be working with this computer. I have tried all the outlets in my house and nothing is charging my laptot.

I'd call HP and request a new power adapter. I've had a few of them go bad before and it's just a short in the cord. Your plug might be loose also...but a good place to start is by calling HP and getting a new cord.

Laptop wont power up HP-Compaq PAVILION DV7-1451NR i push the power button it lights up and then turns right back off. And this is when I have it plugged in. but when its not plugged in it wont do anything...

It sounds like you need a new battery. They do go bad over time. You can probably find a replacement at a battery store or an office supply store. That way, you can try it out and make sure that is the problem. If replacing the battery doesn't fix your problem, you can always return it to the store (or just keep it as a spare).
If replacing the battery doesn't solve the problem, then there is most likely a problem with the port where the power connector plugs in to the laptop. You'll want to contact the manufacturer about that kind of repair, though some local shops might be able to do it.

I need a delete button key cap for an hp hdx 16 laptop

Check ebay as there are sellers that will sell you a single key sparing the trouble and expense of replacing the whole keyboard. They will come with detailed instructions.

Need polarity of adapter plug for HP Pavilion DV6500

The cables for these are fairly specific, but if you have a cbale that has the same plugs and fits both the transformer side and the computer side, you cna use that as a replacement. The cord itself has no polarity.
Are you looking to do something else here?
