thank you and i have many updates waiting in windows update, im little scared to apply them as i have heard so many bad experiences about it,what should i do?
It is simple. Do as what Microsoft and well any mobile device recommends when doing updates, especially firmware upgrade:
1- Have the device plugged in.
2- Have the keyboard attached and in normal typing position, so that the firmware can be updated on the keyboard.
3- Have the device FULLY charged before starting the update.
4- Do NOT interrupt the upgrade process. The device might reboot several times, and the fan might kick-in at full speed. That is all fine. The device might also have nothing displayed on the screen, but still running, that is also fine. Just stand by. It normally takes a few minutes, and it will done. Just leave the device as is. If you interrupt it, then you'll have problems, and even brick the device (can't be repaired. The system firmware chip would need to be replaced). I have seen time and time again, people upgrading their laptop firmware and for some reason freak out, and interrupts the upgrade system, and end up sending it out for repair.
If you follow the above directions you should be fine.
