Hi @astrangeguy
Here's a link that may help with the Windows key problem.
Regarding the battery problem, create a battery report to check the condition of the battery.
Once you have the report, compare the Design Capacity value versus the Full Charge Capacity value. For a good battery they should nearly be the same value. If the Full Charge Capacity value is <40% of the Design Capacity value, you may want to consider replacing the battery.
Try starting the laptop in safe mode with networking and check how long the battery lasts. The display will look different because only basic Windows drivers are loaded and not hardware specific ones, but the idea is to check battery performance. Note that this will only work with a Ethernet cable connection to the internet and not WiFi
If the battery is OK as per the battery report and also when in safe mode, check how many programs are being loaded on Startup. Not all programs loaded on Startup are necessary for correct operation.
Sometimes 3rd party programs installed by you appear in Startup so that they open faster when you want to use them. If however you don't use them that often they are still preloaded so to speak and are using up hardware resources unnecessarily, causing the laptop to work harder than it should. You can disable the program from Startup by right click on the program in Startup and click on disable then restart the laptop. This doesn't affect how the program works. It will still start, open OK etc when clicking on the desktop icon or in the program menus. It just takes slightly longer to open that's all.
Some programs are necessary for correct operation however. If you don't know what the program is used for Google the name to find out. Also only disable one at a time and check. If it causes problems when doing this simply enable them the same way as you disabled them.
