How do I repair my battry

Hi Temjen,

I can't tell whether my difficulty in reading your post is due to translation issues or perhaps English isn't your first language, but I'll take my best guess at what I think you're asking.

Since laptop batteries generally aren't considered to be repairable, I take it you're looking for help with replacing the battery in your laptop. Assuming you've selected the correct model of laptop for the category of your question, it turns out there is actually another device page for that same computer; it just doesn't have the word Presario in it, but I'm assuming they're the same devices given the matching model number.

You'll find a much more complete set of guides on the C700 device page rather than the Presario C700 device page. Here's a link to it.

On that page there is a guide to replacing your battery; it's very simple and should only take you a minute or two.
