Lenovo ThinkPad T40 Power Adapter
If you decide to buy an non-Lenovo adapter, it is imperative to note both the volts and amps outputs. When purchasing a replacement charger, choosing the Lenovo brand one will probably be the safest way to go. The Lenovo ThinkPad T40 AC adapter has two main uses, charging the battery and powering the laptop. Due to the fact that one Lenovo adapter is probably used on other similar units, double-check the part number or model number of the adapter. A universal power adapter is a possibility if you are desperate.
How can I tell if my Lenovo power adapter is crapping out?
- The unit will not run while just using AC power
- Most Lenovo adapters get warm when plugged in for any length of time
- Your Lenovo battery refuses to charge up whatsoever

It is in your best interest to double-check the part number before buying a power adapter replacement. Be sure to always get electronic parts from a site you know when you buy your parts online. The Lenovo ThinkPad T40 will be happier for thinking before buying.
