Warning: Avoid static discharge by grounding yourself using a wrist grounding strap or by touching a bare metal surface like a connector on the back of the laptop and remove all of the power including the battery and power adapter.

Warning: Performing your own repairs may void you warranty!


Notice: Part installations may require BIOs updates.


Notice: After removing or replacing the CPU or heatsink make sure to replace thermal compound or thermal pads on the CPU and heatsink.

    My Dell Latitude E6410 is not taking a charge, even when plugged in. Would it be the battery pack or the C-MOS battery ?

    My Dell Inspirion 3552 will not hold a charge, even when plugged in. I guet a messege saying “The AC power adapter wattage and type cannot be determined. The battery may not charge. Please connect a Dell 45 W AC adapter or greater for best system performance” The thing is, I am connecting to a Dell 45 W AC adapter (if I unplug the adapter, the system will not power up.)

    Hi there. I’m looking for some advice.

    I took apart my Dell-Inspiron 7559 to replace the thermal paste on the CPU and GPU. Once I put it back together, it isn’t turning on. The front white LED lights up (for a couple seconds) when I plug in the power, but the power button does not light up. Presuming I was careful, and that all cables and screws are in place, what could have gone wrong? What parts get commonly damaged which I could cheaply replace?

    I wanted to add, thank you for your guides, your videos and your service! It’s been really helpful, and I love the work you’re doing. I support the right to repair act.

    • Thanks for your feedback.

      Your problem could be one of many. When repairing your laptop there are various things that can be overlooked or even damaged in the process. You might want to first retrace your steps to see if something was left disconnected or needs to be reseated. Unfortunately without having the ability to see your laptop it’s a little hard to diagnose.

  9. E5440. My battery power has been reducing, from 96% last week, to 42% this week, then increasing to 44% and 46% on opening up the machine.
    Do I need a new battery, and will it be fitted by an engineer?
    It seems from checking battery status, that my service contact at expired on September 3rd 2016.
    Many thanks,
    Bob Hutchinson.

    • Hello Bob,

      If you are noticing less charging capacity from your battery it may be time to replace it. Their lifespan is limited and this tends to happen after a few years.
