Buying a second power supply

[ishinryu]

I have seen one but its specs are different to my X31's.
The one I have is:
INPUT: 100-240V 1.2A-0.7A 50/60Hz, OUTPUT: 16V 3.5A

The one I want to buy is:
INPUT: 100-240V 1.4A-0.7A 50/60Hz, OUTPUT: 16V 4.5A

Will it work for me?

As far as I understand, the 16V, 4.5 A power supply should work. Actually, that one is the 72 Watt power supply that IBM often supplies. The one we have for our X series is 16 V, 3.5 A, or about 56 Watts.

As I understand it, the device will only draw as much current (amps) as it needs, so you can get a power supply that supplies more current than the device needs (4.5 A versus 3.5 A). However, the critical component is power: if the device requires 16 V, make sure you get 16 V output on your power supply. Otherwise, you risk damaging the device.

Check with your local electronics store. They can probably tell you more.

Good news but too late for the auction! Thanks anyway.

With more current pumping through the devices, it can potentially charge the battery faster ( cuz this ionized the particules in the battery faster ) but on the flip side, if too much current is passed through the devices, it can demage the devices and battery but for all the power supply IBM sells, they should all charge X series without causing any serious damages.

voltage is only the electrical potential differences between two points on a circuit to generate the current flowing across devices. Higher resistors requires higher voltage for the same current to pass through.

At least this is what I remember from my EE classes many years ago.

The device will only draw the power it needs. You can't "pump" power through a device. So in this case, where the voltages of the two supplies is the same, the larger one will work. I have done that with a different X.
