got think of ask family buy a desktop at home, like that, noneed to carry and worry my laptop that much

if want repair the screen myself.... is it easy to buy replacement screen ???

Heh, I am using a toshiba laptop too, and I regretted because the price can get me a decent MSI gaming laptop. My left speaker is acting up, HDD starts to "spin slower than usual", one edge of the aluminium body has worn off. And while shaking the laptop, I can hear rattling noise inside.

Go get a new one but not toshiba.
