The PC serial number should be on a white bar code sticker on the back of the unit. Look for a sticker on the computer case.

HOW CAN FIX INVALID ELECTRONIC SERIAL NUMBER


In otherwords you are seeing the Activation screen?
No problem!

Primer:
When Windows is installed on a computer, is assigns hash values to certain major hardware components.

Examples such as;
1 Processor
2) Ram Memory

3) Motherboard, (To be more specific; Motherboard chipset, and BIOS program, and version)

4) Harddrive
5) Graphics chipset

Change any two of these hardware components, and Windows will 'think' it is being stolen.

(Windows: "Hey, this isn't the same computer I was put on originally!")

[Microsoft user's license states One GENUINE copy of Windows per ONE computer.

Microsoft makes one Master disk of the Operating System. From it all GENUINE copies are made, and sold ]

Primer over.

When the activation screen comes up, click on - Call Microsoft
I feel it is better to speak to a real person in case there are problems.

Before calling, have the Serial Number of the computer written down, to give to the nice representative on the phone.

This is in a white Service Tag, on the back of the computer, or up on the side of the computer tower.
S/N = Serial Number

After you click on Call Microsoft, the screen in front of you will have a series of blocks.

The top blocks (6) have number/letters in them.
The bottom (6) blocks do not.

The representative will ask you what you wish to do.

ACTIVATE

You then read off the number/letters in the first box, to the representative. Speak CLEARLY, and make sure the representative understands each letter/number.

Go to the second box. Do the same. Do this for all of the boxes.

When finished the representative will state to wait one minute.
(More like; Hold On)

The rep will come back, and state letter/numbers to you.
Put your mouse cursor in the first empty box. Left-click once.

Type the letter/numbers you are given.
Make SURE you understand the representative! IF NOT, ask the rep politely to repeat.

After you have filled the first box, the cursor will automatically jump over to the second box.
Type the letter/numbers in.

Same thing for the 3rd through 6th box.

When finished go back through all the boxes, and repeat back to the rep the letter/numbers. Make SURE they are CORRECT!

When you are finished with the last box, there is a period of silence.
You are supposed to know that you have to click on ACTIVATE, at the bottom.

Click on Activate.

That's it! Say goodbye to the nice representative. Your genuine copy of Windows is now Activated again!

{By the way. You have a new Windows Product key now.
The one in the holographic sticker on the computer is no good now }

Regards,
joecoolvette

Hard drive has been wiped trying to re boot from windows xp cd. changed battery on mother board. getting alert low battery voltage and pc will not re boot. asking re boot trying pressing F1


It sounds like you either got a bad battery or one that is not compatible with your motherboard. Try replacing with a new battery that is compatible with your mb & see if this corrects the error. If you just bought the other battery you are using you should be able to get a refund or store credit towards the new one. Also make sure all the cables are properly seated as one may have come lose during original replacement. Hope this helps.

Error Code 07 301


With IBM Thinkpad,it telling you that some hardware is faulty, check your keyboard to make sure nothing is stuck. Also it could also be your trackpoint. Usually, replacing the damaged part gets rid of the error! However there is a bypass key sequence that allows your to continue booting the system even though it gives you error. I'm not 100% sure of what it is but somthing like ESC at boot or F1 or maybe your need the boot to the error page then press ok, then when the system comes up again press f1 or esc then. You'll have to play around with the key sequence a bit. But to get rid of the error forever you need to replace the damaged part! Regards, Armando
