There is a problem when starting your computer on. The laptop turns on but the display turns black. I've already contacted support but none of their solutions were successful. Upgraded EVERYTING with no solution. Turns out I had to discover myself the problem. It is an issue with the integrated graphics card. As a temporarily solution (while LENOVO upgrades the BIOS to fix this) disable the UMA graphics in the latest BIOS (access by pressing F1 or F2 before Windows loads) and switch it to DISCRETE GPU. I can tell it is not an UMA gpu problem because when starting the laptop for the second time (turning it off previously with power button) the UMA graphics starts normally without a problem.
