vavet,

I've added a comment explaining the values: https://github.com/bitonic/x62-fancontr ... rol.c#L155 . I still don't really know what they _mean_, but that's the effect they have on the fan speed.

Given the PWM terminology one would think that the fan speed regulates the pulse width modulation frequency, but there are a few jumps in the 0-255 range and even in the range where the change is smooth it does not seem to change the fan speed linearly

now onto the next problem: the fan emits a very high frequency vibration at low speeds (which i'm hearing for the first time since it was always at high speed before)

Other than that:

Battery charge and discharge times are a bit... say, they go mad sometimes. I've installed BatteryBar and it worked just fine with both charging and sicharging times... for two days :) then I needed to reinstall it to make sure what is the exact working time and how long would the system stay alive, and still it jumps every 5 seconds to different value, ranging from 3,5hrs to 8hrs on fresh battery (update every 5 seconds).

Is there any reasonable way to create own powerplan on those systems in W7? I guess you can't change voltage on i5 without changing the clock, but a good utility would be nice in here.

You can set a voltage offset (read: undervolt) the X62 with Intel XTU or ThrottleStop (I recommend the latter: Less processor usage, built-in C-state check window which you need anyway for configuring the X62 to save power).

Hi,
Fan control issues here.
Has anyone figured out what the numbers mean in the config file that go along with the Windows fan utility that was posted?
I can't quite figure out how it transitions from one state to another, and additionally it seems to go into states that aren't in the file sometimes (as indicated by the scrolling command line output).

It mostly seems to work for about 10 seconds, then the fan goes silent. Does this have anything to do with how the system cooling policy is set?

I was trying to transcode some video and I ended up with a thermal shutdown...

Hello Rafael,

I'm fighting pretty similar issue here for some time and it seems that the fan behaviour depends on many variables.

There are 4 values in the text file:
a,b,c,d
[up temperature], [down temperature], [fan speed - PWM modulation], [NULL]
up is when to start this speed
down is when to drop to the previous line
fan speed is in 0-100 range (actually did not try more)

When working w/W7 this thing did not work for me, at all. It worked for - say - 30 seconds, and then the fan started living its own way. No matter what I put in there. fullstop.

However, when I installed W10 it actually started working... the opposite. Figuring the numbers in the default thermal table it seems that the lowest fan speed should be there for "100", and the highest one for "1" - and it worked this way for W7 (for a very limited amount of time, however). On windows 10, while on A/C, it works the opposite - highest fan speed is set at "100", and lowest at "1".

I was happy when I found the solution until I switched to battery. Now the nasty thing is living completely on its own; floating between max and min speeds of the fan all the time when the .exe file is on. Another thing is that the temp monitor is unable to execute from W10 autostart (while all the other apps do not have this limitation).

Still fighting. Will let you know when I make it.

EDIT: OK, it works, and it works perfectly. Maybe the only thing I'm missing is sething this app in startup, but this does not seem to work at all. All I did was a BIOS update and W10 update.

Another thing: have no idea if this has been already mentioned, but "BatteryBar" app gives true charge/discharge rates under Windows.

Has anyone managed to update the Intel CPU microcode on an x62?

I'm suspecting that the microcode updates from Intel check the CPU version, and as the x62 has an ES (Engineering Sample) CPU, it will not update.

There are of course other reasons to update the microcode, but patching the Spectre variant 1 vulnerability (https://spectreattack.com/) is my main concern. And we have probably not seen the last of these kind of CPU vulnerabilities that need a microcode fix..

HI,
does anyone know if there are new BIOS versions available for x62?
I have tried all those fitting 2nd batch from https://forum.51nb.com/forum.php?mod=vi ... id=1791568

I am using 10/12. The problem with this version is that it keeps the fan up most of the time, so I have to use the temp monitor tool. I have managed to make it run in the bg with auto resume (stop/start) at computer suspend/resume. the only problem is that the Temp Monitor seem to start misbehaving when some inadequate temp readings appear. The solution can be either a more error tolerant version of the tool (with delayed reaction on temp reading jumps) or a better bios version

Another issue is the low emitted noise from fan when it spins slowly. I am using the maglev fan which emits less noise but still can be annoying. My fan configuration skips these speeds that emit noise, but nevertheless the fan jumps to these speeds due to these wrong temp readings ( I suppose).

Any insights on those issues are welcome.

I got my MiniDP working with a VGA adapter. Neither a MiniDP to HDMI nor MiniDP to DVI adapter would work, though. On the bright side, the VGA one was fully cooperative, and hotplugged without issues.
This was also my experience. I tried a mDP adapter to combo VGA/HDMI/DP and it didn't work. The small adapter that goes from mDP to VGA works fine. My mini-HDMI to full HDMI adapter also does not work, and is annoyingly loose. I'm pretty disappointed with the video output options on this thing. They are a deal breaker for someone on the move which is what the X series is geared for in the first place. I wish they just left the VGA port at this point since it's the only thing that works anyways.

Anyone have any other luck?

mDP -> VGA/HDMI/DP -> doesn't work
mDP -> VGA only -> works
mini-HDMI - > HDMI -> doesn't work

This is the one that is working for me:

AFAIK, the mDP doesn't support DP's HDMI/DVI alternative mode. There are, however, active adapters that decode the DP signal and encode it as HDMI. These should work, but I haven't tried yet.

That certainly sounds like the issue.

Regarding the mini-HDMI port, has anyone gotten it to work? I'm not sure what brand mine is but all it is is a direct mini-HDMI to HDMI port and is very loose and isn't detected at all.

I have used a HDMI screen via a mini-HDMI to HDMI cable at work, worked fine. Don't know the brand, though.

Have a 3rd batch X62 that started auto powering on and then automatically and permanently turning off in a few seconds after until power is removed. After some debugging I noticed it worked with the keyboard removed and later narrowed it down to the keyboard screw closest to the video outputs. If that screw is out or loosened the machine works fine, otherwise it appears to be shorted.

Not sure why it spontaneously started doing this, but wondering if anyone has any ideas on why this might be and if there's a better solution to fixing it besides leaving that screw loose?

Maybe there is some obstruction between chassis and mobo at that point, which causes the mobo to bend there, when the screw is tightened.
Probably a poor solder contact.
Remove the mobo, check, and Dremel the obstruction away if so.

I had some issue similar where sometime the machine would power off or on when ran off battery (no AC connected) -- this was on my tablet X62. In particular I had noticed the power off would happen quiet frequently when the screen was moved. I had narrowed down the problem with the metal plate between the motherboard, keyboard and LCD ribbon cable. I had made some adjustment to the screws a few months ago after sometime the LCD cable would pop out when I'm moving the laptop around. I've now revised my strategy to only screw down the top portion of the cable and leave no screws in the part that connects to the motherboard. It was sufficient enough to avoid the cable from popping out and no more random power on/off issues when on battery.

My only remaining problem is one related to the i915. I sometimes get a random hardware freeze (the functions keys work but nothing else does). It doesn't happen often. But I'll run my laptops using suspend/hibernate so that I'll only reboot maybe once a year. I've gone > 1 year on a lot of my systems in the past. I can sometimes only go a month, a week, sometimes only half a day before I get a hard lock. I first attributed to possibly the ram, but I've ruled that out. I'm convinced it has something to do with the i915 driver or one of the settings I'm using. I'm still using jessie, so I'm using a backport X11 that supports broadwell. I think that might be a contributing factor. On my stable systems, they were always haswell or prior, which didn't require the backport X11 version. I believe I had to move to the backport version years ago due to screen artifact and glitching with i915 broadwell. Anyone using their X62 on Jessie?
