Okay, so this is something I used to actually boost up my old laptop's performance without using any money at all. When it used to overheat, the games I played (Counter Strike: Source, Skyrim, Dota 2, LoL, etc.) had about spikes of FPS lag, oftentimes going low as 14 FPS, because... well, you know. Overheating naturally creates lag spikes in games. After controlling the laptop's fans, my laptop got its nuts kicked and went all the way to 54 FPS, and that's saying quite a lot. I dunno if it'll work for you, but this is a method I learned without any tutorials (pretty sure there are tutorials out there because it's fairly simple).
This works on nearly all the Windows platform-computers.
- Go to Control Panel, then click on Hardware and Sound. If your language is not in English, the icon for Hardware and Sound should have a printer and a disc if you're using Windows 7.
- Click on Power Options.
- Now, your laptop should have a High Performance power mode and a Balanced power mode. High performance is generally recommended for doing things other than gaming, such as work programs, document programs, etc. Balanced power modes are honestly capable enough of running games if overheating is the only problem they have. Click on Change plan settings for the Balanced power mode.. (You can do this on High Performance if you really want to, but it's definitely not exactly needed)
- At this point, you should find that there are extra options at the bottom of the following page. Click on Change advanced power settings.
- Do not change anything in the new window that pops up unless you know what you're doing. Scroll down until you find Processor Power Management. Click the "+" sign to see more options for it. Inside the Processor Power Management options, there will be Minimum Processing State, System Cooling Policy, and Maximum Processing State.
- Since you are wanting to fix your laptop's overheating, click on Maximum Processing State. There will be several numbers that are on 100% and stuff like that. The On battery option is used when your laptop is not plugged into a charger, and the Plugged option is used when your laptop is plugged into a charger. The numbers will determine how much the computer utilizes its CPU to certain limits.
- This is the last part of the tutorial. Click on the number(s) and change the numerical value to anything lower than 100% (my preferences were around 75% the last time I changed it). After that, press OK.
- You're done! You may follow the steps again if you want to change the numbers again, or if you simply want to change more Power Options (ie. High Performance, Power-Saving Mode, etc.). You can do many things with this method, and it could actually save more batteries if you correctly change the Power-Saving mode's options. :D
I think I jotted it all down. Give me a message if it's still not working.
(I'm doing a project right now, so I'll start posting some time today)
