No you will not lose data, but your PS3 may become pregnant.
im so sorry but im afraid you lose everything... it will think you just got it out of the box
you plug it in at the back of the ps3
To plug in your PS3 attach the power cable to the back of the PS3. Then Plug the other end of the power cable into the Electrical socket. Finally connect the output cable to your PS3 and to your TV. Your PS3 is now plugged in and ready to use.
you use a USB 2.0 plug and plug in your psp to a ps3 and you can do remote play.
Is PS3 doesn't work any-more you can swap the HDD's or you can plug both drives form the two PS3's to the computer and copy the files over. If you have stuff on there from the PS Store you could just link your PS3's and download the files again onto your other PS3.
No, on-line data is synced with the MW3 server. You can even buy a brand new ps3 and as long as you know your account info, your on-line account will remain untouched.
If you cleaned it by immersing it in the washing bowl and giving it a good scrub, Yes!
You can plug the PS3 into any TV that has 3 RCA A/V inputs and the Sony Wega has them
The spot to plug it into is in the back of the new slim PS3
yes! just plug it in to your ps3
Plug in the PS3 to a TV. And plug the power cable into an outlet. You turn on the PS3, open the game slot, put the game in, and close it. Then you use the controller that came with the PS3 to play games...
Depends what you are doing, many times they warn you not to turn it off until it is done.
