    I found this fix and seems to work, from tinhow on lenovo forums:
    -Hey man I have the same problems. Try remove the battery and hold on the power button for 30 sec. Put back in the battery and press start. If that doesnt work remove the ultrabay card and then turn should boot up. After that put back in the ultrabay and then turn on. I cant fix this **bleep** problem otherwise and nobody here seems to have a fix-

    original link:
    Not at all, besides I tried that already, I removed the battery, the BIOS battery, checked the voltage, reset CMOS... nothing of that is causing the problem. My problem is way more complex than that.

    The ultra bay do you tried it? Because the ultrabay removal is the key here.

    My notebook does not have the ultrabay thing, it has a DVD reader.

    Just for clarification, whenever this PC has started up correctly during most recent times, was the battery installed or not?

    Have you tried the diagnostic tests that zbook has identified?
    Lenovo Diagnostic Solutions: Diagnose & Fix - PA

    Due to the limited granularity of the tests I doubt the results will be very specific, however; the results may provide some guidance in a particular direction, which is much more than you have now.

    My previously presented theories were based on many years of practical experience working in the Telecom Industry, not from an evening with some good weed.

    I've seen many of these type failures in the past, not with laptops but many others devices.
    This really isn't "black magic".

    Wait, how did you diagnose that?
    It MUST be more complicated than that because remember:
    1. When the battery is plugged in, it won't boot. Well, that's a lie, I've managed to turn it on, just sometimes, but most of the time, inserting the battery means no power on at all.
    2. If AC plugged, it will boot always, but it won't even POST bios, it will freeze in a black screen. Not always, though, you can get lucky one day and suddenly it starts as if it was perfect.
    3. Once it starts correctly, every piece of hardware works, no problems in GPU, CPU, power, or anything.

    A simple cap fail won't make it behave like that, will it?

    Mine is not a paper stone, I've not turned it off since it started correctly a few days ago, I haven't turned it off, and it works fine. I simply can't unplug it. It can restart perfectly fine, by the way. All the problems are related to booting up from a turned off state.
    In my case the battery is not charging. But it will turn on if the battery has small charge on it. Jut the charging is not working.

    The technician managed to switch the battery charge capacitors, but one of them fried. Sadly he can't find one with the same specs. The faulty pieces are the one in this picture. If someone can help me find what are they so I can buy it in Aliexpress, I'll be deeply grateful. Laptop won't turn on if the battery is plugged in (black magic?)-htb1lbkqabgw3kvjszfdq6xwepxad-1-.jpg
