I’m looking for a manual and need to know what kind of Thinkpad I have!

I bought a sony vaio 9 months ago, i have not made recovary discs yet. How can i do it now, which discs i need- double layer or normal dvd? What about my data that already i have in the hard disk, i have to backup them, or any other precautions that i have to take?

I dont know how to fix it, because suddenly the wi-fi function of my Dell D610 Latitude laptop is not working. Please help troubleshoot it.

I have read a couple of reviews that Acer laptops have LCD screen malfunction issues. Has the issue been resolved in the Acer Aspire 5536 model? Seeking feedback of actual users of the laptop or people who know those who use this particular model. Please advise! Thanks in advance!

I want to order one for use with my music software because my current 17 is not huge enough for the kind of editing I do but with this monitor there are 2 horizontal black margins on the top and bottom of the screen. If I set the screen to another resolution so they disappear the screen looks wierd.
I want to not make the mistake of buying the larger screen for nothing. I really like using my macbook with xp. It is stable and I get the best of both worlds but if I wont be able to use a huge apple monitor with it then then I will have to search for a another powerful laptop that I can connect a huge monitor to.
