      Always link the schematic/bdv for faster response.
      Share voltage on all coils after powering on.
      Ram is onboard or slot is used?
      Consumption on dc supply varies while powering on?

          Lenovo Y700-17ISK turn on and off
          by pajdek
          Hello, i have some issues with my laptop Lenovo Y700-17ISK (motherboard BY511 NM-A541), it started when i turn on the laptop, but the lcd wont turn on, i then connected it via hdmi to tv and screen was ok. So i thought maybe lcd stripe is faulty, i removed the bottom cover, disconnected main battery, reset the cmos by disconnecting battery for 1 min, then slighty move the lcd stripe. Conncted power supply and tuned on my laptop, the lcd turn on, it started to load os, then it turn off, after a second it turn on, then after like 3 seconds turn off again, and so on.

          Lenovo y520-15ikbm most of the time doesn't turn on

          Hello,

          I've repaired a few laptops in my life but this time my own laptop died😂.
          Funny enough this one is a bit tough on me.
          It doesn't turn on (most of the time).
          Model: Lenovo y520-15ikbm (NM-391).

          The only way to make it turn on is:
          1) unplug battery + charger + rtc (seems irrelevant)
          2) wait a minute
          3) plug battery/charger in
          4) on charger plugin, laptop turns on by itself. On battery plugin you have to press power button. Sometimes nothing happens and you have to try again.
          5) when it turns on it also displays POST...

          Lenovo G565 Laptop onboard LCD Display does not turn on.
          Only works with external Monitor.
          I am trying to verify that the LCD signals from the motherboard are ok.
          The LCD was working, but over time happened to not turn on more frequently.
          Now dead.
          Possibly the cable from MB to LCD is broken somewhere.

          I just wonder how it is detected if external or internal monitor shall be activated ?

          I found the following schematic on the net:


          Problem 2:
          The graphics chip ATI Mobility Radeon HD5470 seems defective.
