Maybe you really got a defective one.  Why don't you try a replacement?

It would be useful to know what software you are running, which probably has more impact than the act of writing with a stylus.    I've used the various built-in ones as well as onenote and a few others and have had no issues.

 

Ad an experiment, I just tried onenote for 10 minutes in tablet mode.   90% of the back of the tablet is cool to the touch (about ambient).   Right at the CPU in the upper-right, it is just slightly warm, no warmer than an IPAD gets for comparison.   CPU temp reads 41C.    I have TPFancontrol running and the fan never came close to kicking on (I think I've set it for 57C), so it was running totally passive.  Brightness about 60% with no auto-adjust, which makes it quite a bit brighter by default.  The screen itself was not noticeably warm, just a bit above ambient.

 

This is so different from what you're reporting that yours must be defective, or somehow you have something keeping the CPU at 100% and your settings have it running full steam on batteries. 

 

This is with an i7, 8GB 180GB wifi model.

Also, check what process is taking up CPU cycles.

I'm running one note and a web page or two simultaneously and taking handwritten notes. The upper right gets warm but the front panel of glass itself is the part that gets red hot so I can't lay my hand on it while writing, I wasn't implying that the writing with the stylus is what causes the heat I was just asking if anyone else's unit gets that hot while using simply one note and writing with the stylus. I must just have a defective unit. I'm just hesitant to replace it again simply because it was such a shock for me to get this defective unit. But I'm glad it's working out for the rest of you!!

Re: When is the Helix release date?

Slipjack asked about TPFC (ThinkPad Fan Control) experiences. As I mentioned in my longer posting (above), I installed TPFC on my Helix. After a couple days I will say USE WITH CAUTION!

 

TPFC ships with two "Smart Modes" (in other words, with pre-defined fan control schemes). I used "Smart Mode 1", which doesn't start running the fan until things get really hot. It's a very bad choice for the Helix. The temperature of the CPU got into the mid- to high 40s (C), which resulted in a very scary "fry" moment; it looks like it over heated. The only way to shut it down was with the emergency reset hole in back. I should have seen this coming because it was getting awfully hot under my hand as I took notes while listening to a webinar.

 

** Strange thing though is that it should be able to handle temps in the 40s no problem. I'm also testing with IntelBurnTest to see if this was a fan/heat problem or something else (another defect?)

 

So, word to the wise: if you install TPFC and are noticing heat problems, you may wish to use "Smart Mode 2" (very conservative temperature settings) and work your way cautiously up from those levels. Under this scenario, the tablet (out of the dock) is now sitting in front of me in a quiet room with the fan humming along at 3600 RPM and the temperature a nice cool 33 degrees C. It's warmish where the CPU resides (right side top) but not at all uncomfortable. The fan noise is entirely acceptable. Placing the table in the dock results in a boost of the temperature and fan speed, with the fan louder than I like; I'll play with the settings to quiet it down (but carefully this time!) Mind you if you stress the computer at all the fan starts to roar. Running IntelBurnTest quickly gets the temp up into the 60s (C) and the fan blasts away at around 6,000 rpm.

 

If someone figures out a safe but quiet set of thresholds for the various levels before I do, please share.

 

Rob

Localized keyboard layouts already exisst apparently. It's giving me hope for an AZERTY version available before May 2029.

It should have absolutely no problems in the 40C range.    It should be able to run just fine even in the 80C range.    Once it hits about 100C, I believe it will auto-throttle itself.    

 

I changed the levels in smart mode 1 to be a ltitle more conservative than the default:

52 - 0

55 - 1

60 - 2

75 - 3

80 - 7

90 - 128 (bios controlled)

 

At these levels, the fan will generally not run with light browsing, office application work, one note or light game apps.    It will kick on for applications where the CPU goes high for several seconds, which is what I want it to do.

 

It's been perfectly stable with no signs of instability and I've thrown everything I could at it to test it out, including burn-in tests and extended 3D game playing at full resolution (Half Life).

 

I just now tried to duplicate what the unluck other fellow has with screen overheating.   Brought up a couple of browsers , set the screen to 100% brightness with no auto-adjust (so max brightness) and drew with onenote for about 10 minutes.   While the screen was slightly warmish, it was by no means hot.   Very comfortable to draw on.

 

I then even ran the Intel Burn test in addition and continued to use onenote, and while the overall temp increased understandably, there was no discomfort in using the screen, just warmth.

 

I feel quite confident using TPFC set as above, and am even considering bumping the first 3 entries up a little (maybe 53, 57, 62)

FYI, I just got my Helix 2 days ago. I was also concerned about the fan and have been reading through this forum. I just ran the Lenovo System Update utility. It found a BIOS update, as well as some others. I updated all. And now my fan is much quieter, without using TPFC. Hope this helps others! Now that it is quiet, I LOVE the device!

For those interested, I routinely purchase items from Provantage for my company. They currently have 13 of model 36984MU in stock...

 

http://www.provantage.com/lenovo-36984mu~7LENO4R8.htm

 

 

That price is kinda high compared to what I've seen elsewhere

 

I'm waiting on 36984UU myself.
