Question about IBM ThinkPad R40 2722 Notebook
When AC is plugged in, the power light will not light up if the battery is not plugged in. The battery itself is a known problem also and after 3 years it now fails to hold a charge. When plugged in power is sporadic often not lasting long enough to finish the boot up.
This sounds like a power cord or connector problem.
these cords offten break at the back of the connector to the lap top. When you hold it just right it will work. Otherwise it acts up.
If the battery were in good shap it would smooth out the issue but....
Replacment power cord/transfomers are reasonable on e-bay many come out of china and are inexpensive. also consider an all in one type that will be upgradeable for your nest notebook and work in the car or airplane as well as the house. I like Igo brand and Targus but they are a personal preferance.

Check the ac adapter. It seems your adapter is not charging it. Either the ac adapter or your dc port may be the problem. Is this the correct adapter, is it giving the correct voltage. These should be considered also.
Hope this helps you
