Lenovo yoga 3 11 does not turn on, display cable without its cover

Dear greetings and thanks in advance for your suggestions. It is my laptop that never turned on overnight. I discarded the solutions of - hard reset, - the bug of an update of win10 that leaves them dead. The battery must be removed, the power ON button must be pressed for a while to discharge and then turn on. - buy another new charger - turn on without battery and with charger only I found this cable that connects the motherboard to the display in these conditions (see photo). How to know if the motherboard is fried or if changing the cable will turn on? Thank you.

Hi Paula, that is the flexor cable that connects the screen to the card, possibly it made you short, many times they break when opening and closing and more than the Yoga bends, try disconnecting that fexor cable very carefully, pull the black cord , (do not throw to the sides) it is as if I have it on the table I pull it towards my face ok, after doing that and without the cable you just disconnected touch anything on the card turn it on to see if it works, be careful to that that metallic connector touches some part of the card

Do not forget that before doing that you disconnect the battery cable for more security and when you remove that flexor cable you reconnect the battery, when you turn it on you should hear that it works with the hard disk.

Hi. Thank you very much for your answer. I did the procedure you suggested. Be careful not to touch the motherboard. Reconnecting the battery and (as it is discharged) the power plug. Unfortunately it didn't turn on. I paid attention to any noise or if the battery charging light was on. Nothing happened to tell me that he turned on. (The hard drive is solid state).
I performed all the tests with the new and old chargers.
Any other tests that can be done?
Best regards.

Ok I understand because the flexor cable only handles the display since there are other models that do require that cable since the power button is on the display part, then well the only indication that indicates that it is on is that the part of This processor feels hot and if I am not mistaken, your power button also illuminates when you turn on, I really do not remember but well other possible failures because it could be the power button that does not click another is that the solid disk does not work and take off and turn on yoga to see if it shows anything on the screen

The way to guide me to know if really is not turning on would be to turn on and wait a bit and feel if where the processor is hot since every xomputer when turning on the processor works at a temperature obviously if doing so never warms up the processor wants to dextract It doesn't turn on and there are two things that could have happened that made it short. By the flexor cable or that received a discharge and it would be necessary to check components with multimeter to know the status of the same
But check your button and if it turns on it gets hot to know if it works or not

Thank you very much for your answer. Based on what you are telling me, it does not turn on the light or heat the processor. I mean he's not turning on. I have to look for a multimeter to check components. But I saw that the mother does not work.
Maybe sell it in parts?
Greetings and thanks!

Too bad that it is totally dead but it would also be possible that the processor welds have crashed by temperature but it would be better to check it further since in my workshop some dead people arrive and the processor is the cause
But it would already be something that someone with knowledge intervened because there is 80% repair success when they have not been intervened with respect to machinery such as heat machines or so
Good luck greetings
