Question on laptop battery and games

I have a Sager D900C. It runs great but lately its been slowing dow. I think its because of the dust, so i will buy compressed air later on.

Also, my laptop is always plugged in. Can i just remove the batter and just leave it plugged in? Will it work just as well? Reason im saying this is because i never take my laptop anywhere so i find it silly to keep it in. Also would keeping it out decrease the temperatures in my laptop more since i wont have a hot battery in? Any advice would be nice.

 

It won't help decreasing the temperatures. However, since the battery won't heat up, it will deteriorate less over time.

I have my laptop with the battery removed at all times, except when I leave the house with it.

 

so i can still play games with no processor problems etc if i just plug it in without the battery?

 

yea u can play with no problem but if the power goes out, or the plug gets unplugged then u will lose whatever ur doing. (u probably know this already)

 

hehe yea, i was running a game now and looking at it with riva tuner. It got to 90C. Is that way too hot?

 

Yeah, when you're approaching 100 degrees then it's pretty hot...

Notebook Hardware Control gives me a warning when my hard drive temperature reaches 55C and my CPU reaches 80C.
So being at 90C is pretty hot I'd say. You might want to invest in a cooling pad if you play a lot of games.
And cleaning your computer from dust (like you said in your original post) would be a really good idea.

 

yea i have a zalman 2000 cooling pad too but it seems to be not helping much. I notice that when i blow into my cooling pad, dust seems to appear a lot. Maybe i should blow some air into th cooling pad too. That might help/

 

Removing the battery will not decrease system temperatures, it may only make the laptop physically unstable. Reason being the d900 batteries have a rubber support foot underneath them, which makes the laptop sit flat on the surface.
Removing the battery may make the system wobble.

That 90C is way too hot.
You know the D901C has fan control right?
When ever you are gaming press FN+F1 and that will force the fans to full speed. Your temps really shouldn't go over 80C, cause you're heading into the danger zone, especially at 90C.

K-TRON

 

yea i always use the FN+1. I just sprayed my fans with some canned air as well as the laptop cooler which was also full of dust. i think its better now...hopefully

 

Is your videocard at 90C ?

I know for a fact that video cards can reach 100C without being damaged. I know also for a FACT that almost all nvidia cards has a threshold temp at around 110-120C. Why nvidia put the limit there is because it's dangerous when it reaches those high temps.

I don't see why 90C should be dangerous really, as the GPU's are the same thing as in desktops but with lower clocks. So they should tolerate 90C without a problem.


This only applies to graphicscards.


CPU is another thing, then 90C is way to high.

 

Well, it depends on what GPU you have. The nVIDIA 8/9 series has overheating problems that start at around 70C and only get worse the higher you get - hence why they have an unusually high failure rate. So if you've got one of those cards (some say late 7 series are affected, too), then 90C is hotter than you want for your GPU.

Michel.K, those are threshold temps you are quoting. That's when the computer shuts off to avoid imminent damage. You want to stay a good bit below that. My guess is 100C is the highest supported temperature, although I don't know the GPU ones for sure.

CPU though, 90C shouldn't cause any harm, at least if you're Intel. Intel CPU's support up to 100C operating temperature, some 105C. AMD is 95C if I remember correctly. And the threshold temperature is 125C (but that is way too hot). So as long as 90C is the maximum you hit, no harm is being done. Although you really ought to consider undervolting; take a look at Flipfire's Undervolting Guide.

 

Didn't i say "threshold" in my post?


I've modded several BIOS's from the 8-series and all of them had 115C threshold, 8600GT, 8800GT, 8800GTS to mention some.


But yeah, when you say that some notebooks with nvidia-gpus are affected by overheating, yes, that's true, the soldering gets unsoldered when the temps gets too high, so that's why some are very bad to have at high temps.

I'm just saying that they can tolerate high temps without getting damaged, it's just that the solder they used on those chips that are affected was the bad kind of solder. Nothing really gets broken with those temps. But it's nothing even a experienced user can fix in some cases.



I agree on the 90C on the intel-CPU's. Thus, 90C isn't a normal temp for those either But i understand what you're saying.

 

well i just finished doing things here and there to my laptop and the cooler mat. It was full of dust...the cooling mat i mean. Could that have caused the high temps? Also i blew canned air into the laptops fan and heat sink vvents in the back. Now im getting a core temp reading of 42C with the cooler mat on, full fan speed enable. Are those readings better now? Is that core reading accurate?

 

Dust = gives bad/higher temps. So yes.

Well, that's your CPU-temp, 42C is great. How about the GPU-temp that you said was reaching 90C? Is it lower now?

 

around 45C i think thats what everest says right now =D is that ok?

 

Yes that's okey, but when you're not playing or doing any graphics-intensive things, temps never go up to any temps to talk about What i'm saying is that idle-temps aren't important, only load-temps are important to know. As that's when you know if the computer reaches good or bad temps.

 

yea im running a game now in windowed mode while monitoring the temps. Core temp on rivatuner ranges from 67-70C.

Everest says the following:
CPU-47C
CPU1/Core1-45C
CPU1/CORE2-44C
GPU Diode- 71C
FUJITSU MHW2120BH-35C.

Running wow in windowed mode while monitoring the temps. Do these look like reasonable load temps? Which of the two programs temps are more accurate?

 

It looks good.

Start the two programs and see which shows which, do they even show any different values?

 

not by a lot..maybe 2 or 3 degrees diffrence. Everest seems to have that 2-3 degree difference..not a big deal i guess. RivaTuner i just finished checking with wow full screen after 10~ minutes or so after last post, went from 74-77C. I hope thats not too bad.

 

74-77C is totally acceptable. So no worries there!

 

yay! if i see any more fluctuations in the coming days ill just write it here =D! Thanks for the help!!

 

No problem, glad to help
And you do that!

 

well just making a small follow up. I ran a game for about a hour or more and riva told me the core temp was 74-75C. I looked at everest and it said the same thing, the cpu's were well under 40C. Is that fine? I did some more dusting in my laptop this morning hehe.
