Do you know it shows the intellect, of people who post on here, don`t read the rules and straight away committing a ban straight away.
Don`t post your e-mail address it leaves you open to spamming of your mail box, and don`t post your mobile number you silly sausage pradeepkpsg.
And why did you feel the need to do a Bios update if the laptop was working ok before you did it.
