Hello there,
I actually have a Dell Inspiron 1545 laptop. The original battery is dead since 1 year now and I have been plugging the laptop to use it.
It’s after 1 year that I’ve bought a new battery. I charged it fully and then unplug it for use.
When the battery discharge to 75-80%, the laptop goes off by itself. I then tried to switch it on immediately (without recharging the battery) and it works for full 2 hours before the battery is discharged fully.
I’m thinking that maybe something get damaged during the period I used the laptop plugged.
What do you think?
Thank you,
Tiya
