I've used Tweaking.com's repair tool but still I cannot restore the battery icon for my laptop.  I don't know why, when or how it went missing and I am at a loss for what to do next.  There is no way for me to tell how much battery is left, so I have to keep it plugged in.  Coincidentally, I also have a problem with Windows Update.  I can download the updates but there is no link to install them.
Also, the Power icon in the Customize system icons is greyed out and cannot edit it.
I ran antivirus scans too and it shows nothing.  HELP!!!
