Please leave rating if it helps.

All the VAIO computers are shipped with a limited 1 year warranty.
The detailed information on Sony Warranty is available in the below link.

Refer your purchase receipt or contact the sony support team to get the exact warranty status. Provide them with the model # of your computer.

The Hardware Warranty on any computer would cover only defects and failures in the Hardware due to workmanship or manufacture. The Hardware Warranty will not cover anything that gets broken due to user interaction on the computer.
Hence, the Hardware Warranty will not cover any part that a user of a computer breaks (either intentionally or unintentionally).
I understand that your laptop is a Toshiba.
Just to let you know, Dell offers a Complete Care warranty over and above the normal Hardware Warranty, in orde to cover unintentional damage to a computer.
But, in your case, to be honest, I do not think the breakage to the laptop or any part of the laptop would be covered under the normal Hardware Warranty.
But please get in touch with Toshiba support (800) 457-7777 (toll-free) or (949) 859-4273 (I am presuming that you are in the US) and get things clarified :-

This model of Sony VAIO Computer is out of warranty. Sony Provide 1 year of warranty for all the models.

You should inform the customer about the warranty coverage. You have to let them know that onece the warranty expires they will be limitted for any support any computer manufacturer does have that kind of policy. IF they have reported the issue before the warranty ends they should still be entitled for any support or possible repair you can do but they we're not able to report it before warranty expired it's their responsibility to take actions with the system. I believe all computers got initial 1 year warranty for it .

Click here to access the Acer warranty information page. This site will help you know the warranty status of your Acer machine. Type the serial number of your machine on the system Serial textbox and press Find Serial Number Button. You may locate the serial number of your computer at the bottom of laptop computer.

Logitech equipments are usually pretty good. It should be under warranty so I would not try to fix it yourself.
If you bought your product new from an authorised dealer, your expensive speakers would still be under the normal Logitech 2 yeas sound systems warranty: consult your warranty terms an contact both your dealer and Logitech support.
Hope it helps. let me know how you go.

Contact Microsoft. I know they will send out new computers with XP but only by request. You're going to send it in and be without it for awhile.

If, and that's a big if, Microsoft does it.

If not, you need a SATA drive to copy all your data, and then get an XP boot up disk to overwrite your vista OS.

I'll assume you mean your computers warranty.
All the computers I've purchased have used the purchaser information as warranty verification.Normally you don't have to register. If you've been prompted to somewhere read the fine print. It's usually a way to get you to submit to periodic offers by email as well as offering update checks (sometimes every time you turn your computer on, which is a good way to really slow your computer down). HP is a common culprit. Some software you do have to register and you'll usually find that in the help tab of the particular program.
If you did not buy the computer from a retail or computer mfgr. but you know it's still under warranty go to that mfgr's website and see if you can find the registration there.
Let me know if this helps

Amber,

My guess is, as you also have guessed, the internal wireless card. Since it is under warranty, there should not be charge for it but I don't know the details of your extended warranty.
