1. Laptop is used to carry from place to place…so people who travel a lot must think of the weight of the laptop.

2. Every battery has a lifetime. So going for a Laptop with hardly any battery backup is not suggested. Minimum of 45 minutes battery backup is very necessary. So while purchasing the secondhand laptop please keep in mind to check the laptop only on battery for minimum 30 minutes and also keep an eye on battery usage indicator.

3. Carry with yourself an audio, video & Blank CD/DVD so that u can check the audio section and video section of the laptop including the CD/DVD read/write test.

4. Run the scandisk utility available in all versions of windows and check for bad sector in hard disk.

5. Take with yourself any external device like thumb drive to test the USB port.

6. Take with yourself SD memory card to test Card Reader (If the option is available on the laptop)

7. Take any good floppy to test the floppy drive (Any how current Laptops are not coming with Floppy Drive)

8. Take an external headphone and microphone to test the external audio port.

9. Attach the laptop to the external monitor to check the external VGA port is working or not.

10. Open any word file and check all the keys are working or not.

11. Check for battery charging for 5 to 10 minutes and see the battery indicator is showing charging.

12. Press the window and the break keys on the keyboard and see the amount of RAM and CPU details.
Further chick the hardware option and then the Device manager to see all driver are installed or not. There should be no Exclamation mark.

13. Slide the LCD screen slowly on the hinges and check any flicker on the display if so there may be a problem on the connector cable driving the LCD circuit of the laptop.

14. Also check the Modem, Bluetooth & Wi-Fi Port if available on your laptop to be purchased (Do only if you know) I will be writing on these subject next.

15. Check the laptop minimum for 45 minutes to see whether laptop hangs or restarts or shutdowns.

16. See the Laptop User manual and Driver CD are there with the Laptop.

17. See that u get a laptop carry case, otherwise u have to purchase one.

18. If all the conditions meets out OK and within your budget just go for it.

19. Happy LAPTOPing.
