Battery shows 100% but laptop dies as soon as I unplug it

[TallerMike]

The battery on my laptop has been working fine. Suddenly, however, unplugging the computer from the charger causes the laptop to die instantly. The laptop will not power on or light up unless plugged in. When plugged in the battery meter shows 100%.

• I have tried different chargers which work fine on my other HP EliteBook 830
• I have tried updating and rolling back my BIOS updates
• I have tried opening the back and reseating the battery

Check your battery and computer. When you're done charging your laptop click on the battery and see the percentage. If problem persists, try changing your battery. Before that, also check your battery usage and see which program is using the most power. If it is okay to do so, get rid of that program. If none of the ways on top works, you'll have no choice but bring it to a place that fixes laptops and ask for help.

The battery is at 100% The laptop shuts off immediately so it's not an application which is using the battery up.
