I have a 'top spec' Dell XPS 15 (L521x). I've only had it for a year and it's had it's screen changed, motherboard, touch pad and ssd all break and need replacing... At first after a few weeks of owning it the screen went black, but I could operate everything through an external monitor via a hdmi cable. So a dell engineer came out and changed the screen, but it still didn't work. The next day another came out who replaced the screen again along with the motherboard, still wouldn't work oh and he snapped the base of my laptop... Next day I requested a different engineer who again changed the motherboard and tested a new screen, still it wouldn't work, he then came back with a new ssd hoping it would solve the problem as well as a new base. This fixed my problem but now the touch pad stopped working... This then got replaced and all seemed to be working fine until the other day when the screens backlight went off. Now a new engineer has come out and replaced my screen, and now nothing is coming up on the screen... They are bringing me a new motherboard tomorrow to hopefully fix it! This is worrying me that it's going to be a regular thing now, any suggestions?
