Precision M4600 Unknown AC Adapter/Battery Not Charging

[ssj92]

I got a m4600 originally to dissect the 2960XM from it for my Alienware M18xR1. It originally needed a bottom cover, cpu fan and battery. 

 

I ended up getting it all minus the battery. I did borrow a battery from a M4800 and found out it doesn't charge. 

 

All my AC Adapters (180w, 210w, 330w, 240w) show us as unknown ac adapter. I replaced the dc jack recently and it still has the same issue. 

 

Is it a motherboard issue? Was hoping to get it fully running at this point.

Hi ssj92, I have the same problem with my M4600 with a charging issue too. My laptop adapter is PA-1151-06D2, and it doesn't charge, but I use the M4800 original laptop ac adapter to M4600 it charges fine.

 

Did you try to use the M4800 laptop ac adapter to M4600? Try to swap the M4800 CMOS battery for the M4600 Battery.

its likely a very old battery, materials inside degraded to the point it cannot hold charge,
from your description it is clear that your system boots just fine with no errors,
try removing the old battery form the chassis and see if you get the same behavior,

Battery is fine. It’s from my M4800 which works perfectly fine with battery. It’s most likely motherboard , either way I sold the M4600.
