    EliteBook 2530p - LA-4021 Schematics needed

    Hi All,

    I'm seeking help for a complete schematic diagram of an EliteBook 2530p "JATOO LA-4021P Rev:1.0" motherboard? I'm currently fixing a dead laptop of this model (no power). I already searched around the net but what I can get is the 36-page schematics that doesn't include the Power Supply pages.

    Would highly appreciate if someone kindhearted can share the schematics.

    Thanks & Best Regards,
    K-Whiz

      Thank you very much 580shahzad for your help.

      But I still don't see how the 19.5 Volts from the Adapter is coming into the circuit, nor any part in the schematics show how this voltage is further stepped-down and regulated into different voltages. This diagram is the same as what I have downloaded from the internet (36-page), there could be one that shows more of the circuit.

      Hope anyone can shed a light, as I believe the problem is just near the 19.5 volts part of the circuit.

      Thanks & Best Regards,
      K-Whiz

          Thank you very much piernov,

          Your complete schematics was very helpful. I fixed one 2530p with broken on-board fuse. Another 2530p is waiting for a replacement component.

            I'm pretty new to motherboard repair. Would you please explain where to look in these schematics for 19V adapter? I think I could slowly go from there... Maybe

            Thanks
