A/C Adapter compatibility question, please help me!

  • I have a Dell Inspiron 9100 which uses the following A/C power adapter:

    Model # ADP-150EB (PA-15 - P/N D2746)
    150W
    Input 100-240V ~ 2500mA 50-60Hz.
    Output 19.5V 7700mA 

    What I would like to know is if I could use another A/C power adapter with my computer? Let me explain a friend of mine gave me his spare XPS2 laptop A/C power adapter.

    Here are the specs for that adapter:
    130W
    Model: PA-1131-02D (PA-13 - DP/N 9Y819)
    Input 100-240V ~ 50-60Hz 2.5A.
    Output 19.5V 6.7A

    All I want to know is if this adapter is compatible with my Inpiron 9100 since all the plugs are the same and the specs seem almost identical?

    Thanks in advance.

  • It's risky. If the system is designed to run with a 150W power supply, substituting a 120W could cause problems (including damaging the adapter and mainboard).
