My laptop switches from 'Power Saver' to 'High Performance' power option when I launch a game

[Kydulus]

I am on a Windows 7 64-bit Pavilion g7 notebook. A little backstory: its gotten pretty ragged over the years and the two main issues are:

1). loud fan noise when the CPU is under extra stress. Rarely gets to excruciating levels

2). not sure if this is a problem with the battery or the cable but for over a year the battery has not retained any charge and I have to constantly keep the laptop plugged in to keep it on. If I hover over the battery widget on the toolbar it says 0% available (Plugged in, not charging) and I have to do a little trick with the power button each morning to get it to turn back on. This isn't a huge deal since I only use this pc at home.

Because of problem 1 I have to keep the power options set to 'Power Saver' instead of 'High Performance' or 'Recommended' because the fan will get too loud otherwise. For the past few days I've had a problem where if I launch a game, for example Mount & Blade through Steam, the power options automatically switch off of Power Saver. If I don't catch it and change it back manually then the fan gets really, really loud.

Manually switching it back after I launch the game is not a huge problem, but if I play the game for an extended period of time it'll switch back on its own, and it doesn't take a long time of being off of Power Saver for the fan to get to the point where its substantially annoying me and other people in the house

I do not know a lot tech issues but this seems like a truly bizarre issue and I couldn't find any similar problems or solutions anywhere. Tl;dr my crappy laptop is randomly switching off of Power Saver and this is causing issues with fan noise. How do I get it to stay on Power Saver indefinitely?

I would suggest going into the full details window for the power options. Not just the main choice screen.

1. Go to "Control Panel" and click "Power Options".
2. Click the "Change plan settings" link and on the next screen click the "Change advanced power settings" link.
3. In this new window that launches, check all listed options to make sure the settings aren't set up to switch modes on you.
4. You may also want to check all the options for the others as well (high performance, etc.,). You don't have to change your main choice to those, just check their listed options in this same window.
5. When you are done with all your changes, make sure the window is set back to the performance type you want to be using, and be sure you click the "Apply" button and then the "OK" button.
