|... That's what happens when you have a "naff" battery they'll last a "couple a three" years, then wo'nt hold the "charge"|
... I use a laptop with a no-good battery all the time with the mains hooked-up of course.
... running off "just the battery" will make the laptop run slower as power is drained and the cpu steps down to compensate.
... if you use the laptop because you travel and need to use it via battery buy a new one! . (battery)
