Thank you all for great help. You're really nice guys
I'm gonna buy the laptop tomorrow, information is enough for me, now just need to be sure that everything will be checked before giving out the money.
Hope that it'll be a good deal.
Thanks a lot
P/S: Here will be my checklist
Serial validity:
- Case (same serial number with laptop)
- Customs paper, sale invoice
- When booting, press F11 to see serial number in BIOS to see if it’s the same.
- In windows, use ‘dxdiag’ command to check
CPU:
- Use CPU Identification of Intel to check
General:
- Check for scratches and screws
- Press Thinkpad + F11 to let the laptop automatically check for its hardwares (if there is a illegal hardware, the warning will be displayed. The hardwares MUST have the same serial)
- Smooth dark case with a bit special smell
CD
- Use some CD / DVD to play
Speaker:
- Play a song
Keyboard:
- Check all the keys
LCD
- Check if there is any dead pixel in the screen
Hardwares
- Use some tools like (Event, SIW) to see the hardware if the hardware is genuine.
RAM, HDD - Maybe I will use Hiren's Boot CD to check them
Again, thank you mates
