Another strange issue I have maybe you can help me on this one Ive thought on opening a seperate thread on this one. I just got an HP and though the battery works and holds for about an hour. There is two major issues I got with it. After reading its model online its supposed to last about 3 hours but it only lasts about one( with barely use). Something I dont like. Since its a modern pc and it has an updated OS it should last longer but it doesnt. Then and this one I really hate. I take off the pc from charger its starts eating up the battery which I dont think its normal. If I dont charge it for about 3 days it kills the battery completely and makes the computer loses some of its configuration. I dont think any of that is normal. I explained it to the seller/ tech and he said all of that is normal to which I dont buy in the least.
Be aware that the "battery duration" announced by the various manufacturers are when you use minimum display brightness and when the machine is idle...so from 3 hours announced, 1 hour is more the realistic duration especially if you have a wide screen 17-18inches (more energy needed) or a powerful CPU/GPU.
About the 20% limit, i learned it the hard way, i ,one day, forgot to turn off my very old laptop, and it reaches 5%, then shut down by "security" , problem it never turned on anymore
