    Dell Vostro 3400 Charge problem
    by Vusal
    The main problem with the laptop is that the charge does not rise to 56%.
    I found a bios from this forum and wrote it. This time the charge increased normally.
    But I get a problem manufactured error. I added the original bios files. The battery was tested and it is fully charged in another machine....
