Laptop Dies After Unplugging from Charger

[nscott51]

My laptop no longer functions unless constantly plugged in. On Wednesday, yesterday, I accidentally used my laptop until it died on me. No big deal, I plugged it in and let it charge overnight. Next morning, today, I check the battery and it's at 100%. Perfect! I unplug it and start my day of classes. Except, 5 minutes into my first class, my laptop shuts off and refuses to turn on until I get home later than day and plug it in. I see the battery is still at 100%, I didn't misread it or whatever, so I go ahead and unplug it again. My laptop then immediately turns off and won't turn back on until I've plugged it in again. I don't think my battery is bad since, before it died yesterday, I could use it for 5-6 hours constantly before it started reaching low battery levels. I looked it up and saw that many HP laptops can get this issue, and that it's a power management setting. The solution I found says that I need to switch to a power option labeled "Rixane Power Scheme" so that my laptop will return to switching to battery power instead of always relying on AC power(hence why it dies after being unplugged), but I do not have this power scheme as an option. All I have is "High", "Recommended", and "Energy Saver". I've looked all over in my settings, control panel, advanced options for the power schemes I have, but nowhere am I able to find the setting that controls the power source my laptop uses when it is not plugged in. Help?

The power switching occurs outside the operating system at the BIOS level so there is nothing you should have to set. You need to run a diagnostic on the battery. Tap esc + f2 as you power up or use the HP Support Assistant to do a full check of the battery health. Odds are good, but not 100% that replacing the battery will fix the issue. How old is the laptop?

Oh, ok. I used the HP Support Assistant and it says my primary battery is working just fine. I can't do the other option since the computer uses a bluetooth keyboard that doesn't connect to the computer until after the computer has powered on.  The laptop isn't old at all, I got it in May of 2015.

The computer may not be old but a battery that is 2.3 years old is entering its senior citizen zone. 

Use the advanced reporting option on the HP Support Assistant to get the details...the "OK" on the battery test is kind of like an idiot light on the dashboard....I am more of a gauges guy...I want to see the oil pressure and the voltage. Metaphorically in this case.

Really? I suppose technology isn't made to last anymore. My old laptop is still up and running at nearing 6 years old with a still healthy battery, though it was used daily for the first three years.
