DRILLING? THEN VACUUM!
Drilling something is fine, but no one above mentioned to VACUUM THE FILINGS out of the laptop. Drilling will likely leave tons of filings of a ferrous nature. These could short traces or other areas inside the laptop. Drilling would therefore be my last choice. If you are going to drill, turn on a shop vacuum or any vacuum for that matter while you drill. At least that way, the last amount of filings possible will go into your device.
