The makers don't document this or why but half our laptops do that at the office.
I need advice about the laptop battery. I only use my Acer laptop as back-up. I fully-charged the battery 3 weeks ago but when I needed to use it this weekend, the battery had lost all its power. How could the Lithium-ion battery become completely deleted when the unit was shut-off? On the other hand, the battery in my digital camera holds the charge for months. Why the discrepancy?
