laptop battery died ..hope do i replace it Evo 600c?

Answer 1

Replace it or have the cells replaced. Once a battery is gone, its gone. Cell replacements are about 50-60 for your unit.

Just do a search for "EVO 600 battery" to see all sorts of places that have replacements.

Here is a sample of what I found

or for comparison shopping
