Keys sticking or ot functioning. the "i" sticks, the "p" does not work. Have taken off key to clean, but still not functioning. help!

Hi Janie
Dont panic... I'm sure there is a simple fix. But you really must remember your passwords better. There are many Apps and software programs to help you with this. Find a good method & stick with it. The future of passwords & security can only get harder.
You haven't mentioned what brand / model you are dealing with. This does make it hard for anyone to troubleshoot.
Find your manual. get an online PDF manual to learn the key sequences to press to wake it up or reset the device. Where did you purchase? Perhaps they can help!
Cheers

try to use memory stick on any other computer....

and you will see if it's problem of computer or memory stick....

if it's problem of memory stick, then another computer will not read it either...

if another computer can read it, just make copy of your stuff to another USB key (memory stick)

if not, use some free software from internet, to analyze and recover memory stick..... simply use google and you will find that freeware

if you are not good with computers, ask someone more experienced

hi this could be several reasons for not working firstly it could have been liquid damaged /spillage etc check keys are they sticking when pressed if so you will need to remove panel and remove keypad and clean the unit iff this fails check lead at base of keypad entering the board this might have come lose or even broken away .you might even try changing the keypad if all fails hope this helps you

it came with a toll, it is on the bottom right side ot the ipad u stick the tool in the hole

Ok, Rob, did you buy the memory from Compaq/HP? Or is it a 3rd party set (ie. Viking, PNY, etc.)? Sometimes, Compaq/HP computers are VERY picky about the specifications of the memory that the mother boards will use. 

If you bought them from a 3rd party vendor, I would recommend taking them back and exchanging them for another brand or even just another set of sticks, but, before we go that route, let's try something else. 

Install a 1gb stick and the 512Mb stick and then go into the BIOS and see how much ram is being registered there. If it reads all 1.5Gb of ram, then we know it is something else, if not, then we have somewhere else to look. 

Assuming the BIOS registered the full amount of ram, try removing the 512Mb stick and then boot the computer, enter the BIOS and see if it is reading the 1gb stick properly. Assuming it did register the 1gb properly, swap the 2 1gb sticks out and repeat. If it did NOT register the lone 1gb stick, try moving the 1 gb stick to the other socket, and checking the BIOS again. If that works, then swap the 1gb sticks out, repeat the BIOS check.
Assuming that after you swap out the 2 sticks and they both work as lone sticks, go back into the BIOS and look for an advanced page or an option to turn on a "Diagnostic Mode" or "Memory Test", and run the memory test on each stick- one sitck at a time, to see if there is a minor/major memory addressing issue, with either stick. 

If they both pass individually, then, try reinstalling them both together and check to see if you can reach the BIOS with them both in place. If not try putting the 512 in the 0 or first memory slot and the 1gb in the second slot, then repeat the memory test, swap the 1gb sticks again, and repeat the memory test on the second stick- (the thinking here is that if it is not the memory sticks themselves, perhaps it is the motherboard or one of the sockets for the ram that is bad).

If you can reach the BIOS with both 1gb sticks in place, but, not actually boot to the operating system, then it is possibly a timing issue- this SHOULD BE AUTOMATICALLY configured, but, if you are an overclocker or a "performance wonk" you may have changed a relevant setting in the bios that controls the speed at which the memory and the processor interact. Or it could be a problem with windows hardware monitor not accepting the changes to the amount of memory in the machine. To test this possibility try going into "safe mode" at boot up, after the BIOS screen/Compaq logo has come and gone.

If you can boot into safe mode and not into regular mode, it is a problem with something in windows. Sometimes, just booting into safe mode alone will fix it, sometimes, it is necessary to run the restore DVD on the computer to fix the problem windows is having/ or alternatively reinstall windows without running the restore DVD, using this method will usually fix windows, with out deleting all of your data. You might have to reinstall a few programs afterward, but, your pictures, mp3s, document files, etc. will still be on the drive. Running the restore DVD almost always deletes your data, so USE THAT SOLUTION AS A VERY LAST RESORT, ONLY AFTER YOU HAVE TRIED EVERY other option I have given you. 

Good luck, and hope this helps. 

The NumLk key controls the number function.

it is input device as mouse. it is use in to play game. we can operate game by arrow key in key bord. But joistick is as handle, we can roated it any direction so it hehps easy to play game. we can get it in usb and serial. thanks

Space key sticks bcoz there is a spring below that key & that is move from it's lock this needs to be opened & this spring needs to be adjust this will help you............

Let's start as simple as possible:
Do you have a loose connection / glitch at the power-connector? Check and solder (link to manual for disassembly is further down in this document)

To me this looks like a stuck key (not necessary one on the keyboard):

create live-usb-ubuntu:
1. download and burn ubuntu 8.10 to cd.
2. boot _any_ computer with it, connect >1GB USB stick.
3. System --> Administration --> Install to live usb
4. Boot from live-usb-stick that you just created
5. open terminal (Applications --> Accessories --> terminal)
6. paste this: sudo apt-get install xev
7. paste this: xev
8. hover with mouse over white box
9. make sure not to press any keys or move the mouse. Now flip the screen or try to recreate a situation in which the task manager would pop up in windows.
10. what's the output in the terminal window? Try to pinpoint exactly how and when the events are generated.

There should be no event generated, when you physically flip the display (which means you don't have to replace the hinge).
Press every single key you can find on the laptop. Verify that each key generates exactly one event.

If you find that there is a series of events generated without any key pressed, try to clean the malfunctioning key. (Service manual for disassembly)

It might possibly be a broken hinge (20USD). Flipping the display and pressing soft keys (Q, rotate, e) does not generate events in xev. Any other button does.

You need to clean the keyboard. Blow it with air blower so that the paricles inside keyboard will be eliminated. If not work, then you disassemble the keyboard and clean the key one by one. afraid to do , then let the repairman do it for you or you can attach USB keyboard for the laptop.
