@jiayi29 and Jomjolu: Welcome to the MSI family!!!
CPU temp apps? I personally use HWiNFO64, it's tiny, quick, is native 64-bit and provides all the info I need in cute tiny coloured tray icons. Plus it works with the MSI Afterburner app to provide in-game OSD for temp-monitoring (read: you can check your temps IN GAME). Finally because the developer is a nice guy who QUICKLY repairs whatever problems you can report about his app (personal experience).
If you need more WOW bling bling effects, try out Rainmeter. For ULTIMATE customization, there's Samurize, but that's effing hard to set up.
As for laptop coolers, it depends; but generally they DO help. Take care in purchasing a cooler though, don't get something that pushes air into the wrong places (check your air intake vents first), and the cheapest "good" cooler I can recommend is the Coolermaster X-Lite II, as it uses a huge-ass fan that blows air EVERYWHERE.
As for batteries and plugs... Well, let me tell you a story. I tried gaming on the GE40 with my battery out one time and my adapter got fried. Bzzzt pop. So, while taking the battery out helps prolong the life of the battery, it MIGHT kill (or at least shorten the life of) your adapter - especially if your laptop (the GX60) has strange power consumption habits like my GE40 (130++w max power intake, 90w adapter provided. Go figure).
Also if your laptop has NOS advertised (like certain other MSIs like the GT70) DON'T PULL OUT YOUR BATTERY because NOS is just MSI's fancy way of saying "we know for sure this thing will require more power than just your adapter can provide at full load".
But then again, the battery is RM500++ and universal adapters are RM100++, so uh... it's your call.
@Unseen83: Is it a "Driver Power State Failure" BSOD? If that's the case it's your Bluetooth. Bluetooth has been throwing this error SINCE Vista and I have NO IDEA why Microsoft isn't fixing it.
All you need to do is to uncheck "allow the computer to turn off this device to save power" under Hardware --> Generic Bluetooth Adapter (or whatever) --> Properties (click on the admin button) --> Power Management. Poof, no more Bluetooth BSODs.
That said, besides that particular Bluetooth BSOD (and that HORRIFYING Uxtheme Windows Update conflict that needed me to completely RESET the laptop - PLEASE USE UXSTYLE TO THEME WINDOWS PEOPLE), I have NEVER had any other BSODs or such issues so far.
EDIT: "Kernel-Power 41 (63) error" seems to be related to audio driver conflicts. One guy had 3 audio drivers installed at the same time (lolwut?) and he got that error. Try checking your audio drivers if you you get this.
so far it's been 2 days I used my laptop with the battery taken out and still looks ok
