    I have a problem with charging battery. The laptop charges intermittently. To make it charge I have to move the adapter plug a little bit. After that it starts charging again but after a while stops again until I move the plug. How can I fix it?

      Tina, it’s either bad AC adapter or failing DC jack (shown in the step 19). You can try another AC adapter. If the problem is still there, this is DC jack problem. To fix it, it’s necessary to remove the motherboard and replace the DC jack which is soldered to the motherboard. This should be done by a professional repair shop.
      Again, check your power supply first.

      Search on eBay for “K501 cable” and you’ll find one.
      I think the LVDS cable part number is 14005-01610600 or 14005-01611100.

      marco, in order to disconnect the keyboard it’s necessary to remove the laptop base cover (steps 1 and 2) and disconnect the keyboard cable from the motherboard (step 18). In the step 18 you can see the keyboard cable color-coded in yellow.

    The right hinge on my broke. Do you know if by merely opening it up that the hinge can be replaced without significant difficulty? Or would it require replacing the entire displace/screen panel?
