T60 WS Heat

Hey all. I had a quick question for owners/users of the T60, specifically the 15.4" WS, though it may apply to all T60's.

I don't seem to have any problems with heat, though it gets warm on the bottom; however, the bottom edge of the frame gets quite warm, not hot enough to prevent me from holding my hand to it, but definitely noticeably warmer than anywhere else on the notebook. The area is right above the LED indicators on the frame of the screen. Can anybody check theirs to see if this is normal?

Edit: After feeling it a little more, it's only hot on the right side. The left side below the screen is warm but definitely not as warm as the right side (above the LED indicators seems to be the warmest place, correlation?). Thanks!

 

My good friend has the T-60 and it's definitely much warmer than my dv6000t not sure why exactly why but it seems to be normal for that series.

 

Although my T60 is not the widescreen version, I have not had any issues with heat. The area you mention is not enough warm on mine. In fact, the only time mine gets warm is when it is plugged in.

But, like I said, I don't have a widescreen, so that may be usual.

 

I have the WS T60 and I have no heat issues. I've been working on battery power all morning, and the area you mention is not hot at all.

 

Checking it running on battery power it doesn't seem to be a problem. It does seem slightly warmer than other areas but is definitely not a problem. However, plugged in it gets quite warm. Could you check next time you're plugged in?

 

I dont have my laptop on right now, but you may want to refer to this:

It is the systems diagram of the T60. The only thing around that area is the CPU , which is more towards the middle, and then the battery. I believe it probably is the battery that gets a little warm when its plugged in because you're recharging it.

/shrug ? I dont remember if you got the ATi or Intel integrated graphics. Regardless though, the ATi X1400 is in the lower left palmrest area, so it isn't the video card.

 

I have the ATi card, but it's not the problem. I'm not sure if it's the battery or the CPU because it's definitely on the frame of the LCD screen. I've included a picture below (which is probably what I should have done from the beginning, sorry) with the heat area encircled in red. It gets quite hot, but I think it's only when it is plugged in.

 

oh. I see what you mean now. I thought you meant the area below the LEDs, aka, thespace in between the print screen/scroll lock/pause buttons and the LEDs. Yeah, I'm running my laptop on battery and can feel the area being slightly warm. I dont think its something to really be concerned about. Perhaps it has something to do with the backlight (errr.. but then if it was the backlight then the whole bottom would be warm..hmmm)... LEDs produce very little heat, so it can't be the indicator LEDs... /shrug I'm about as clueless as you are.

 

Yeah, I wasn't sure if this was a major issue or not. I did also think it may be the backlight, but ruled that out due to the uneven heat. It makes me a little nervous only because nowhere else on the laptop is that hot when plugged in.

 

Well, I think you shouldn't worry about it too much. I've had my laptop on the past hour just doing internet and email and it is barely warm (running on battery).

You copied my sig ....

 

lol, i didn't even notice that. I had some spare time today so i figured i'd throw my configuration up . quick OT question, but how long does your 9-cell batt. last? I milked 3 hours out of my 6-cell with no wireless and low screen brightness doing some word/ppt documents.

 

I am using RMClock, with screen brightness set to 4/7, Wireless off, running off Ethernet, is set to be managed by the BIOS (not using RMClock's profiles such as performance on demand. By using RMClock's Performance on Demand profile I get about .5 hrs less battery life!! I haven't tried using RMClock's max battery, which locks your CPU speed to its lowest). Mine seems to last about 5-6 hours.

ThinkVantage Power Manager Settings:
CPU Speed: Adaptive
Optimize Fan Control: Balance
Brightness: 4/7

I'm sure if I set the brightness even lower and set the CPU speed to Low/Lowest it can go even further.

I am still toying with RMClock to maximize my battery life. The nice thing about RMClock is the ability to undervolt. Basically from what I understand, the mobile Core 2 Duos dont actually need all the voltage. They can run fine with lower amounts of voltage which leads to lower temperatures which leads to longer battery life. I am still playing around with it, although I actually seem to be getting the best results using the Power Manager instead of using RMClock directly. I only use RMClock to set the VID to .9750V for the 12x multiplier, whereas I think normally its 1.2500V.
