I dont know my PUK code

Finding a PUK (Personal Unblocking Key) number is not tough job. To find a PUK code all you have to do is call up on the customer care number and ask them to help you with the issue. Before they provide you the PUK code, they will ask you several questions. You need to give them the appropriate information. Customer care of your service provider are the only source from which can give you the PUK code.

At the time when you enter a wrong pin number three times. The phone asks you for a PUK number. The PUK code is generally eight digit number This PUK number is an unlocking code which helps you to unlock the phone and use it. If you enter a wrong PUK number 10 times than you simcard gets rejected. Then you will have to but a new simcard. It might happen that your phone might ask you for PUK2 after you enter your PUK number.

I have a 2 year extended warranty on my computer.I bought in Nov.09.My battery wont keep a charge.What do i need to do?

Your battery has a warranty same as your laptop. Contact Acer and they replace your computer's battery FREE OF CHARGE.
Be ready with your contact details, cellphone number, shipping address and most important of all your computer's serial number. They need the serial number so they could look up for the right battery for your computer.

Call this number: 1-800-571-2237.

Need to add a prefix

First of all you must enter the program mode if you have your manual it will tell you how to do this. If not try this. press the # and on the screen should show command and a flashing number with a question mark. Enter the number 700 and press enter. this will get you in the prefixes. use the next key to scroll until you a a line with no numbers, it may take a little bit depending on how many prefixes are entered. Now then you use the arrow key to get past the first 3 digits that are flashing, enter the number 01 for non toll calls arrow over one more time enter the number to access an outside line commonly 9 then the prefix excatly how it is dialed eg.( 001 01 91800 05). Recap the 001 is what number in the list of approved prefixes. 01 is non toll call. 9 is the access number dialed form the room to get an outside line. 1800 is the first numbers dialed to call a number like 1800DIRECT. 05 is the number of digits dialed including 9. If you have any problems with this email me donnie_rawls2002 at Hope this helps. I had to do this today at a local hotel and it was a bit confusing in finding the right commands and how to get there.

Comp wont start up

The hard disk may have died. Check the BIOS and check the hard disk setting, if it appears OK then boot up with a DOS floppy startup boot disk, and select boot up without CD-ROM support, then type fdisk, answer Y to large disk support, select 4 to Display partition information.
If you see all your disk partition the most likely your hard disk is OK.
Most likely you operating system is damaged/corrupted and you will need to reinstall your operating system and drivers for all your devices.
