EliteBook 2530p - LA-4021 Schematics needed

[K_Whiz]

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
