Laptop power problem

[dessie]

I recently put on my laptop but the screen is dull like the power is low but
when i use the power supply it stays dull but it says its charging, but the
percentage never rises. When i take out the power lead the screen brightens
up like it is fully charged, but i get a message saying to use the power
supply as the battery is low. I do this then the screen is dull again. Any
one any ideas.

p/s iused a different power supply but still the same problem.

What about the battery? Replaced it?

Sounds like the battery is bad. Not only is it not holding the charge it is
wasting(shorting) power from the supply. This could be a serious problem
Li-Ion batteries have been known to explode. Or you could just have a fire.
Damage to the computer and/or charger are likely even if the more exciting
prospects don't develope. Replace The battery. Don't use the computer with
that battery in it. Can't say for sure that its completely safe to do so but
it'd be better to use the supply alone until replacement.

Good Luck

Some laptops have power options that change the display brightness. If
some of the options get reversed, the bright dim display illumination
might also be reversed.

That aside, it sounds like the internal laptop power supply is going
bad. Bad capacitors can cause this sort of problem if the external power
supply has poor filtering or output voltage problems under load. In
turn, this can be caused by an internal laptop power supply problem.
