Helix CPU frequency limited to 0,3 GHz after replacement of mainboard (Win 8.1)

Hi,
I have a weird problem: The mainboard of my Helix was replaced by Lenovo because it was defective. Now, the CPU frequency does not exceed 0,3 GHz (16% CPU utilization). The laptop is unusable because it is soooo slow. See the screenshot below.
The technician who exchanged it says: "hardware is ok, please "Format C:", it's a software problem " I don't want to do that.
The Lenovo support says: "We don't know."
I tried to run and reinstall Lenovo Solution Center to run a hardware scan, but the service doesn't work.
Who can help? Is this a software or hardware problem?
Christian

Do battery levels have any influence on this?
Does it change anything if you unplug the charger?
Did you hard reset both the tablet and the base using a pin?
Do you have the latest BIOS?
If so is "Cool Mode" turned off and power settings set to "max performance"?
Do you have the latest Lenovo Power Management (PM) driver installed?
Did you try switching around between power plans (in Windows - RMB on the battery icon)?

How to Define Specific CPU Frequency in Laptop Mode Tools?

I would like to know how to set a specific maximum and minimum frequency for Laptop Mode Tools. Here is my /etc/laptop-mode/conf.d/cpufreq.conf:

No, I just want to save battery power. I don't want the CPU to be clocked as high when I'm on battery. I would set the CPUFreq governor to ondemand, but when I issue sudo cpupower frequency-set -g ondemand, I get:
Setting cpu: 0
Error setting new values. Common errors:
- Do you have proper administration rights? (super-user?)
- Is the governor you requested available and modprobed?
- Trying to set an invalid policy?
- Trying to set a specific frequency, but userspace governor is not available,
for example because of hardware which cannot be set to a specific frequency
or because the userspace governor isn't loaded?
The output of ls /lib/modules/$(uname -r)/kernel/drivers/cpufreq/ is:
acpi-cpufreq.ko.gz cpufreq_stats.ko.gz powernow-k8.ko.gz
amd_freq_sensitivity.ko.gz cpufreq_userspace.ko.gz speedstep-lib.ko.gz
cpufreq_conservative.ko.gz p4-clockmod.ko.gz
cpufreq_powersave.ko.gz pcc-cpufreq.ko.gz
Doing modprobe cpufreq_ondemand and trying again does nothing.
So, since I can't use the ondemand governor and then raise the threshold, I need to limit the CPU frequency.
Thanks.

T42 CPU scaling limited

I have a IBM T42 Laptop with got acpi running.
I can control the speed of the CPU stragely only
1.80 GHz
1.60 GHz

I'd like to be able to trottle it down to 600MHz, thats also what's the value of /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_min_freq : 600000
An other try would be cpudynd but that stops with:

P6NGM-L and CPU frequency confusion

Hello all,
Me again. with more questions about my P6NGM-L, BIOS V3.6. These are different questions than in my other topic, so I thought it best to start a new topic.
Anyway, I've just had my E6300 upgraded to an E8500 and it's working fine. However, while both CPU-z and my mobo's BIOS show that it's an E8500 @ 3166Mhz, they also show that the 'current cpu frequency' is hovering around 2000Mhz. I would understand this if I'd had the EIST enabled, but I hadn't at the time (I have now enabled it).
So can anyone tell me what's going on?
Also, while I was looking in the downloaded manual for the mobo to see if it had any info on this, I noticed that it says (somewhere, though I can't find it now. ) 'this board supports overclocking' although of course they don't make any guarantees (Why should they?). I was hoping to overclock my 3.166GHz cpu to 3.33 GHz, but I can't change the Bus speed or the Multiplier. Currently '333MHz and x6' in CPUID and in the BIOS the multiplier is 'x7'.
So is it possible to change any of these things so that I can run the CPU as if it's an E8600, or slightly better?
Any help anyone could give would be much appreciated.

Thanks for the replies Nichrome and XFM.
Nichrome,
I hadn't touched the BIOS for anything to do with the CPU until I enabled the Enhanced Speedstep setting, and before then the BIOS was showing the cpu as 3.16Ghz but showing the frequency as 2000Mhz, after enabling EIST, the BIOS shows both a CPU of 3.16Ghz and a frequency of 3.16Ghz!?
I can't find any way of overclocking the CPU, unless I have to mess about with the memory timings first?
XFM,
I've looked at the link you were good enough to post. I've done the 'My Computer - Properties' thing and it does show two separate speeds. I'm just wondering why my BIOS now (the last time I looked, anyway) didn't show two separate speeds.
I'm sure either this pc or my next one will send me mental.

CPU frequency does not down-clock when idle, Power waste or is this OK?

I was browsing through the BSD sysctl's of OSX 10.6.2 today and noticed something I thought odd. Looking this up on different searches produced no useful results so I thought I'd ask here.
It seems that the MacBook late 2006 Core2Duo T7200 model has no cpu speed scaling. As far as I can tell, looking in the 'sysctl' output gave me these results:
sysctl -a |grep freq
hw.busfrequency = 664000000
hw.cpufrequency = 2000000000
hw.tbfrequency = 1000000000
hw.busfrequency: 664000000
hw.busfrequency_min: 664000000
hw.busfrequency_max: 664000000
hw.cpufrequency: 2000000000
hw.cpufrequency_min: 2000000000
hw.cpufrequency_max: 2000000000
hw.tbfrequency: 1000000000
What this shows, CPU frequency maximum minimum are both 2 GHz, bus max and min are also 664mhz. These should be able to change I would think.
(The "tbfrequency" value I believe is timer speed; 1gigahertz assures smooth media playback and interactivity. This is not the issue)
I was under the impression that Core 2 Duo's were supposed to have "SpeedStep", to make the cpu run slower to draw less power and generate less heat. On my desktop, this definitely works and I have measured it with my Kill-A-Watt meter. I would think the same happens with all cpus, so I wonder: In my macbook, is the lack of slowing down the CPU using more power than necessary?
(edited to add more detail)

I'm sure it's slightly less efficient. However, any CPU will still use a lot less power when there's less of a load (as you can see by running CPU-intensive tasks and watching the battery drain compared to when nothing is open).

K7N2GM-V - Please re-setting CPU Frequencies in the CMOS Setup (sic)

Rebooting after a system hang I sporadically get the following messages:
CMOS Checksum error - Defaults Loaded
Warning! the CPU had changed.
Please re-setting CPU Frequencies in the CMOS Setup
Could someone please translate this for me? I haven't touched the CPU, the CMOS jumper and the battery is good, per the hardware detection menu.
And my CMOS settings are lost, so I have to go back and set the clock, disable the floppy I don't have, boot order, etc.

The battery contacts are clean; in or out of the case the mobo boots fine as long as I don't pull the plug.
But for the answer to my original question, what does this mean:
Please re-setting CPU Frequencies in the CMOS SetupThe Quick User's Guide is not useful here. It says:
Adjust CPU FSB Frequence
This setting allows you to select the CPU Front Size Bus clock frequency. Settings [100MHz]~[300MHz] at 1MHz increment.
In fact with High Performance Mode set to Optimized the choices are only 100, 133, 166, 200, and the answer given is correct:
Quote from: osnavi on 28-July-05, 22:27:47
"...Do you mean the BIOS setting "Adjust CPU FSB FRequency?"
The choices there are 100, 133, 166, 200... " If CPU is 333 FSB you should select 166.
In other words, in the BIOS set up screen, go to Cell Menu and then Adjust CPU FSB Frequency and set it to ½ the advertised frequency of your Athlon CPU.

Does the iphone cpu frequency change when the cpu load is different?

Does the iphone cpu frequency change when the cpu load is different, or it does not change, stay a fixed frequency? if it changes, how can i get the realtime cpu frequency?if anyone knows,please tell me, thank you so much!!!

As a general, historical statement Tonefox is correct. For certain particular cpus woodmeister is correct. Cpus have historically been single frequency units, though over-clocking has been done for several years. Doing so pushes the cpu beyond its guaranteed speed, but has tended to work since most cpus from quality vendors will actually operate at higher speeds. The manufacturer just does not guarantee the results...remember the Pentium fiasco in the early years of that chip? Today manufacturers are ceertifying particular product lines for over-clocking on a periodic basis. And that is what dynamic clocking really is, over-clocking but not at a constant clock speed as has been done in the past.
Much of the silicon on the market will function at higher clock rates, the only question is does the maker guarantee the accuracy and performance at those clock rates.

Cpu frequency scaling not working and hdd powers down

Hi,
I recently made a fresh reinstall on my laptop keeping only my user settings (home directory) but no system-wide settings (/etc).
Now I have the following issues:
1) CPU frequency scaling does not work. KDE's PowerDevil tells me, my CPU does not have scaling capability and when I try to start cpufreq, I get this error message:
# /etc/rc.d/cpufreq start
:: Setting cpufreq governing rules , cpu 0 1Error setting new values. Common errors: [BUSY] - Do you have proper administration rights? (super-user?)ble_governors: No such file or directory
- Is the governor you requested available and modprobed?
- Trying to set an invalid policy?
- Trying to set a specific frequency, but userspace governor is not available,
for example because of hardware which cannot be set to a specific frequency
or because the userspace governor isn't loaded?
The governor modules are loaded:
# lsmod | grep cpufreq
cpufreq_userspace 2096 0
cpufreq_powersave 942 0
cpufreq_ondemand 7990 0
freq_table 2339 1 cpufreq_ondemand
cpufreq_conservative 9172 0
This used to work out-of-the box with the previous install so I'm a bit puzzled.
2) My hard drive powers down after a few seconds of inactivity, just to power up a few seconds later when it's accessed again. The hard drive never powered down on my previous installation. I do not have any power management daemons running and this behavior starts right after booting the machine, before I log in.
I would like to disable this "feature" since I think it's rather bad for the hard drive's health as well as battery life.
Any ideas?:)
EDIT: Cpu frequency scaling is fixed now, forgot to load the acpi_cpufreq module.:rolleyes: There's still the issue with the hard drive, though.

The HDD thing is caused by upowerd, dunno why though.
You can try: hdparm -B 254 <disk device>, but that wont solve the problem permanently, only till you plug and unplug again the AC supply.
you can also try killing upowerd and things will (at least that was the case for me) be alright.
Maybe this is upowerd bug?

Why the CPU Frequency will just stated at 1189MHz when the X230 had AC Power ONLY (Battery Removed)?

Dear All,
I bought a X230 (i7) notebook. I found that if removed the battery from the notebook and only use AC power with the X230 Notenook. The CPU frequency will stated at 1189MHz. It will not change no matter how many program the notebook is running. The CPU frequency will rise to 2.9GHz or upto Turbo when the Notebook with battery or battery and AC power. Why the CPU Frequency will just stated at 1189MHz when the X230 had AC Power ONLY (Battery Removed)? This is not right. Any setting in the X230 Notebook need to change? Please help.
Solved!
Go to Solution.

RichardW wrote:
The situation is probably the same as it was for the X220. A 65W power adapter by itself doesn't provide enough power to run the computer at full speed, but it can when combined with a battery. However the 90W adapter may be able to run the computer at full speed without a battery.
As it was with earler X-series. This is by design. It allows people to travel with the smaller, lighter 65W adapter. However for maximum speed and flexibility it's best to always use the 90W adapter.

do you save the settings before exiting bios? also make sure that you clear your bios once by removing the battery for 10 min, in order to clear all rezidual information.

Setting CPU Frequency

I have an Intel Core 2 Duo E6400 CPU (2.13Ghz, 1066mhz FSB) in a MSI P965 Neo motherboard but in the BIOS the CPU frequency is only showing 533mhz. Is this normal and actually is running higher or do I need to change a setting to boost it to the supported 1066mhz?
*Update: I updated to the latest BIOS (v1.4 from v1.3) and it no longer displays the FSB.... I'm guessing it was just a reporting error and their fix was to no longer report it >.>

I had the same issue with my E6400 showing 533 MHz in BIOS. I'm not worried and have chaulked it up to:
1) Speedstep while in DOS/BIOS
2) A calculation error in BIOS
CPU-z 1.35 correctly shows it as 2.1 and shows it dynamically go up and down with SpeedStep.
Finally, my CPU mark and 3DMark scores are all within range of similar Conroe system.
So, this is a reporting issue not an actual performance issue.

Haswell i7 cpu frequency

Hi,
I have an i7-4700MQ laptop with a cpu frequency range of 800mhz to 2.4ghz (3.4ghz with turbo).
When using kernel 3.12 it would stay at 2.4ghz, but after the update to 3.14 it would clock down to 800mhz.
Now since the release of 3.15 it seems that it will never go down to 800mhz again, even if left idle for a long time.
Is this a known issue? is there something i need to do?
It does fluctuate down to about 1.3ghz for very short periods but i havent seen it go lower.
i can force it down to lower frequencies by changing
/sys/devices/system/cpu/intel_pstate/max_perf_pct
but that is a bit of a hack and not exactly dynamic.
any advice would be welcome.
Thanks.

As graysky said, it's the latter. Quoting myself from the thread I linked to:
Ondemand was doing unnecessary work, it's not needed to scale the freq all the time, because it's the C-states that power saving comes from. So the "my CPU is always at max freq" thing is indeed not an issue. The CPU is *not* at the max freq all the time, it's only at the shown freq in the C0 state. And on a working system, the C0 state will be used less than 1% of the time.
If you want to do some tests, add intel_pstate=disable to the kernel commandline, so that the acpi_cpufreq governor will be used instead of intel_pstate. Then use turbostat (it's in AUR) to compare how the CPU behaves with each of them.

7125v1.0 Neo4 Ultra - CPU Frequency wrong

Config: MB:7125v1.D0, CPU: 3700+, Ram: 2*1GHz Gskill, VGA: Sparkle 6600GT PSU: Corsair VX550W, 2 IDE & 2 Sata Disks (Non-Raid)
Hello,
MB is non-overclocked (never), but Cell Menu in Bios (v1.D0 - last disponible on MSI Site) shows:
Current CPU Clock 2211MHZ , Current DDR Clock.
I don't know when and how the frequency changed... at the time I flashed the Bios, frequency was 200MHz.
Actually, I can change, after windows has started, the frequency from 201 to 200MHz using the Nvidia Control Panel.
Even if Board is working with 201MHz clock, isn't it better - or am i wrong? - that frequency is not higher than 200MHz?
Is there any way to change this in the Bios, so the frequency is what it has to be?
In Cell Menu, these 2 lines (the first 2 of the screen) are grayed and said non-changeable.
I tried a Cmos-Clear, as indicated otherwhere (power cord unplugged, battery removed, waiting at least 15Mn, etc..) but nothing changed. I also tried to reinstall XP entirely on another clean disk, but CPU Frequency remains at 201MHz.
Is it possible to reflash the 1.D0 Bios on the same Bios and will it change the frequency?
What happens if I reflash the same Bios on that which is in use?
Or is it better consider reflashing an older Bios, and after that reflash the newer?
Tia for any help
Regards

Well what's the matter 200.5 or 200.0, you can try to disable CPU Spread spectrum it can affect 0.5 in the freq.
Hello,
I apologize not to have answered before, but I was traveling for work the last 3 weeks.
I asked about the HTT frequence because it is generally said not to change the Ram Speed over the previous speed.
Even when I let 201Mhz for CPU Clock, i have some bugs (unexpected reboot after various time, unexpected PC freezing) - not always but from time to time. When I change the CPU Speed to 200 MHz with NVidia controlpanel, just after windows has started, these bugs never ! appear.
Changing the CPU Spread Spectrum option in the cellmenu has no effect.
So I'm wondering that i have this default which exists also when i make a new XP Install on a new disk: FSb Clock 201MHz CPU Clock 2211MHz instead of 200/2200. Ok with the multiplier factor it is right but The RAM Frequence is also 402 MHz.

How to make GNOME power management auto scale cpu frequency?

Hello everyone, I installed Archlinux on my new Toshiba U400/H00, everything works nicely, however, I need to manually scale cpu frequency when on AC/Battery, is there a way to make Gnome automatically scale it?
Thanks a lot!

Maybe just go down to acpid level and do it independently of DE devs idiosyncrasies?
For me, the following code in /etc/acpi/handler.sh does the job:
ac_adapter)
case "$2" in
ACAD)
case "$4" in
00000000)
echo ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
echo 1500 > /proc/sys/vm/dirty_writeback_centisecs
00000001)
echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
echo 499 > /proc/sys/vm/dirty_writeback_centisecs
esac
*) logger "ACPI action undefined: $2" ;;
esac
I believe the original code there tried to set fixed clockspeeds for these situations, but I find changing governor much more flexible.
Edit: there were some ACPI-related bugs during 2.6.26-27 development cycle, it may happen that you won't get any ACPI events playing with power source. 2.6.28 cured all ACPI problems for me, but YMMV.
