Is using an adaptor that has 90 Watts be okay to use for a Lenovo 3000 n100?

2009-08-30, 4:20 AM

I have a Lenovo 3000 N100 and the AC adaptor for it died.  The adaptor was a 65 Watts 20 VA.  I tried a replacement one that has 90 Watts 20 VA and it works great.  However, l am wondering if I should continue to use the 90 Watts one or if I should go and purchase a 65 one.


To clarify, both 90 and 60 watts are mentioned as adaptors for this computer yet I am not sure if using one with more watts would damage my laptop.  Would using an adaptor with the same Va but with 20 more watts damage my lenovo 3000 n100?

yes it is okay. More watts wouldn't damage the laptop, as the wattage supplied by the adapter depends on on how much the laptop needs, it doesn't supply the full 65 w or 90 w all the time.


Conversly, if you use a 65 w adapter in a machine which constantly needs 90 w, then it could cause some problem, as this will cause adapter overheating due to current overdraw.
