I have an IBM Thinkpad T42p. I bought a universal power adapter for it the other day, which advertises compatibility with the T-series. However, on the bottom of the laptop, its input power requirements are listed as 72W (4.5 amps at 16 volts), whereas the universal power adapter is only rated to produce a maximum of 65W.
Might this cause any problems for me, or will I just notice it in the form of slower battery charging when I’m using the computer?
There are higher-wattage universal power adapters being sold, but everyone seems to be sold out of them.
