I bought my Fujitsu laptop in Sweden can I use the charger it came with with an adaptor in USA. It seems like my battery is not staying charged as long after using in in USA for about 1 month. Wondering if I am frying my battery..
Most any laptop from recent years comes with an AC adapter that accepts "universal" voltage. You can confirm by checking your adapter and verifying that it says "100-240V" or similar.
If your battery doesn't seem to last as long as it used to, maybe you use it a lot, or you're doing different things, or you're draining it down all the way before recharging, or your battery is defective, or any number of possibilities, really.
