recently, i just repair my laptop model Asus K501lx' s screen. after the replace a new screen. i notice that the new screen resolution was a normal lcd screen with 1366 x 768. the original screen was LED LCD with 1920 x 1080 full hd. besides, lot of the laptop software cant running properly and took too long to start up.
I talked to joseph on geek squad support phone number, he suggested to replace the hdd with sdd. After installing the windows on the new ssd the problem is resolved.
