    l505- es5015

    the board is : 6050A2301901-mb-A02
    power issue:
    the power button 3v is present, but when press it the volt will stay 3v and will never be zero, even if i touch the 2 pins of the power jumper,
    the 5v and 3v are both present
    i tried to flash the bios
    the bios battery was zero and changed it
    iput 330 uf x4 instead of token
    the charge is working fine, i found the 3.3v on battery pinouts
    one thing i get is 1 led with no life

      by air_chair256
      Hello,

      I have a Lenovo MB LC40CM 19863-1 when press button is pushed the keyboard backlight turns on and off twice and the power button light keeps blinking and the fans spins for a few seconds and stops then again spins and stops (Three times) then laptop turns off. no image on screen. sometime when you leave it for few days it will turn on and work but once you restart it won't turn on.

      Tried to reball RAM 1,2,3,4
      Checked all voltages on big coils all present except 1V_VCCGT is not present I get 0V on this rail. is this voltage should be present once power button...

      Surface Pro 7 - SLP_S4 present, then gone
      by Prott
      Hello fellow Badcappers,
      I have a problem with stubborn Surface Pro 7. I narowed it down to disappearing SLP_S4# (gone after around 200 ms).

      Everything else works as it should (the whole power on sequence succesfully finishes, all the voltages are present) until this signal goes missing - with it missing the AND gate causes ALL_SYS_PWRGD to go back low and this makes VCCIN drop to 0 V as well. Interestingly the SLP_S4_DRV# signal from SAM is still present for a second, even after SLP_S4 is no longer there. I wonder what could either cause PCH to stop sending the signal or what...

      Hello everyone.
      lap and motherboard : IdeaPad 3-15IGL05 Laptop - Type 81WQ
      NM-C961.
      Behaviour : connect charger it power on automatically ,reach 0.170 amp than down to 0.74 amp...no display.
      with battery connected it reach 980 amp than 870 ...no display
      No short ; no corrision no intervention before.
      Try 2 differents bios versions same behaviour.

      Some measuremets :
      PL 1600 = 5valw present
      pl 1100 = 3 vlalw present
      pl 100 = 0.221 v without battery and when battery connected 7.8 volt
      pl 6602 = 1.2 v
      pl 6603 = 1.056v...
