How do I fix the heavy damage to my Toshiba Satellite?

If you have an external monitor and keyboard, this will fix your issues at a low cost. If the 3 key keeps doing it’s thing even with the external keyboard attached, then you must disconnect the laptop’s keyboard. When you do, check and see if it has a sticker with the part number on it, then check amazon or ebay for that part. It might be worth it. Also for the monitor. It depends of course on the prices and your budget. You can also get the part numbers by checking your laptop’s model. I hope this helps! :)
