does a laptop vibrate?is it normal?
depends if your laptop has a sub woofer built in but the likely case of vibration is the internal fan if ur under warenty ring them to take it bk and have a look at it if ur warenty has ran out unscew the bottom and check the fan is clean and if moveing freely
If you have CD or DVD in drive then it will vibrates when you access drives. Make sure you remove the CD/DVD when you are using it and don't want to see your laptop in vibrate mode.
