If it does not shutdown with only battery then definetly there is short. Short could be either at the adapter or at the connector on the laptop. Most likely the connector on the laptop.
Thanks for the guide. I did up to step 2 but step 3 seems tough. I cannot find which part that I can remove first, the palm rest or the part right above the keyboard toward the screen. I never open any HP laptop, need hint for step 3. Thank you.
I recently purchased HP HDX18t with P8400 processor, I want to upgrade to X9100 myself but do not know how to disassemble the unit to access processor area. Can anyone has experience on this laptop give me the step-by-step guide. Thanks a lot.
