So I dropped my Lenovo Ideapad 710s, only had it a few months and it cost £700. I thought I'd got away with it...it spread eagled itself flat on a wooden floor face down, amazingly the screen did not break, but the impact was fairly hefty as it bent/creased the aluminium back cover and one of the threaded tabs on the palmrest broke where the keyboard couldn't bend to match the back cover!
So it all seemed to be working fine so I araldited the threaded block back onto the palmrest, and managed to pop the back cover straight and bend out the crease.
Last night it wouldn't turn on, keyboard would light up, fans operate briefly. Took the covers back off, unplugged battery and held down the power button etc. Left it charging overnight. This morning I systematically when round the board unplugging various components to see if it would start up without, for example, the keyboard.
Eventually threw in the towel and went to find the charger for my elderly chromebook, failed at that but found a micro-HDMI to HDMI lead so hooked the Lenovo up to my TV. Success...its alive! I also through desperation, managed to finally get the laptop to share its screen with the TV.
Its a fairly new model so there is not much in the way of spares on ebay. Do I just plump for a screen assembly or could the fault be on the mainboard? Any way of finding out? Although it showed no signs of damage, I'm hoping its 'just' the screen on the basis its casting and outputting on the HDMI port...
