Thinkpad L520 Power Management Issues

Hi all,
I have to report several issues with my Thinkpad (Core i5 2520M).
Both seem to be related to power management, that's why I decided to put them in one thread.
The problems occur on battery and with ac power connected, I have a 90 Watt power supply.
I am running Windows 7 x64 on my laptop, and I've applied all patches from Microsoft Update and Lenovo System Update.
All drivers are up to date. I am using the latest BIOS file (1.20).
The first problem is: My Thinkpad does not automatically increase CPU speed, it is always staying at 800 Mhz.
Even running Prime95 does not trigger some upscaling.
I experienced the same behaviour under Ubuntu 12.04 LTS, which I booted to check the problem.
In Windows, I set all power management options to full power (Windows Energy Control Panel and Lenovo Power Manager as well), still no change. 
A complete BIOS reset (with removing the CMOS battery) did not change the situation.
The only workaround so far is, to run a software called "ThrottleStop", and to uncheck the box saying "BD PROCHOT". After doing so, the CPU is scaling up to 2.5 Ghz, but still does not enter Turbo mode.
The program has to be re-run after every boot to enable upscaling.
The second issue is:
I have bought a secondary hard drive bay, and the containing disk keeps spinning down after a few seconds of idle. (Yes, seconds!) The disk is working fine, does not have SMART errors and does not show this behaviour in another laptop and as an external USB drive.
I disabled all power savings options again (Window, Power Manager, and Disk AAPM), which could cause such behaviour, but still no luck. The first hard drive is an SSD, therefore I can't tell, if this drive is also affected by that behaviour.
 UPDATE: After booting Ubuntu 12.04 LTS, I can verify that the behaviour is identical to Windows.
Since both of these problems seem to be related to some part of the power management, I am wondering if there is some bug in the BIOS itself or maybe some faulty system driver.
Any help on that would be appreciated, since normally working with the Thinkpad is rather annoying, considering the slow speed and the constant spin-up/down of the drive.
Best,
schalli

Hi,
   everybody suggests "hdparm -B 254 /dev/sdxxxx". This does NOT work. At all. The Load Cycle Count keeps going up. The 2nd HDD (in the CD/hdd caddy) powers down every few seconds, then up again.
   I found this works: "hdparm -S 25 /dev/sdxxxxx" (change sdXXX in sda, sdb, or whatever relevant to your case). It sets spindown every 25*5 seconds. Second hdd is practically always on and LoadCycleCount remains constant. 
I am also using "hdparam -S 0" to disable drive power management entirely.

Please Please can you check something for me?
I have two hard drives (second is in aftermarket caddy), but it seems the second hd (the one in the caddy) is NOT seen by BIOS at boot. So I can only boot from the internal hdd. After booting, the second hdd is seen by Linux, SATA link reports 3Gb, no issues, all is fine.
Same here, the secondary hard drive is not seen in BIOS or in the BIOS boot menu.
After booting Windows/Linux, the drive works fine.
 UPDATE: Even in good ol' DOS, the drive is seen. (I just booted DOS for a firmware update of an SSD drive, which was installed in the hard drive caddy.)
Where did you get the BIOS v1.32? The latest on the Lenovo Website and in System Update is 1.20..
Can you verify something for me too?
On my L520, Turbo Mode does not work at all, how about yours?
You can verify under Windows using hwinfo (http://www.hwinfo.com/ ).
 For Linux, there's http://code.google.com/p/i7z/ , but you'll have to compile it.

  • Thinkpad X60 - Power Manager issue

    Hi,
    I just have to install the Power Manager version 1.89 into my Thinkpad x60.
    However, it shows the "Black" Triangle which is located next to the power manager guage in the task bar.
    Before the installation, I have not this problem. And I am using the genuine battery.
    Could anyone help ? Any previous version can I download to avoid that problem?
    Thanks,
    Tlee

    While I see the information of the black triagnle, it shows "my battery can run 3.x hrs, the new battery can run 5.x hrs" and inform the link to lenovo. It seems ask the user to purchase the new battery.
    But I want to point out. my battery is in good condition. I think I no need to purchase the new battery at the time.
    Now, my battery is suddenly damaged. While I read the my battery information from the power manger, it shows 99% capacity. But the current is " 0 ". It seems the battery is internal locked.
    It is not really likes as you said the battery would likely fail soon. Since, I can use it more than 3 hrs continously ( 8Cells)
    Also, I searched many posts and indicated that my battery is the detect unit within Lenovo recall program FRU no: 93P5029.
    But nobody inform me before. Now, the recall program is expired..............

  • Power Mac G5 DP1.8GHz - Bad Logic Board or Power Management Issue?

    I have a Power Mac G5 DP1.8GHz/1.5GB/80GB which I bought non-working. It has not yet been disassembled or examined by a certified tech. This is it's issue (which replicates): the computer powers on. It makes a single warning tone, then the LED flashed at least 15 times (too fast to count). Then the posting chord is heard. Hard drive spins up. Then nothing (no video). Won’t boot from any disk. I have changed the RAM and tested the RAM banks with known-to-be-good RAM from another DP1.8GHz G5. The warning tone stopped once or twice after this switch, but then it didn’t chime. I changed the PRAM battery, but not with as new one. However, after installing the used one and then resetting the PMU, it displayed video briefly for the first time. While installed in the other 1.8GHz G5, the hard drive was formatted, given a clean install of OS X 10.4.11, and then moved into this computer where is never mounts. The computer is not accessible through TDM.
    Do I have a bad logic board? Bad CPUs? A power managment issue? A RAM issue?

    Through my own trial and error troubleshooting, I have found the CPUs to be in good working order and the logic board passes the Apple Service Diagnostic every time. Despite the installation of numerous pairs of modules that worked in another DP1.8GHz, the computer has a RAM issue-it gives the "no good RAM" tone most of the time when it powers up (after a PMU reset it does not). Also the computer boots from disk or into Open Firmware but the disk utility can't see either hard drive so I may have a bad SATA controller.

  • Power management issue USB 2.0 Root Hub

    USB 2.0 Root Hub
    Power management issue.
    The check box of the Function (Allow the computer to turn off this device to save power)  Remains always unchecked , it does not matter if you check it , in the next check in the properties window it will be unchecked again .
    My problem is that my system does not hibernate if I set time more than 15 minutes or so.
    The system stays-On for ever, I have check for software issues, but everything looks normal, at my search for power management problems in drivers, I found this issue, with the USB 2 controller.
    I have unplug any USB device from it, and the power management status does not change also.
     The INTEL driver file is very fresh, 29/4/2004.
    Does any one have any ideas, Beta driver or other solution?

    Well i think that i found my real problem , even if the above issue is not 100% responsible for my troubles .
    The AVAST antivirus was blocking the hibernation , by one function called as ( On acces file check ) .
    I did disable it , and my system now hibernates .
    The point is that even now , i am not 100% certen that the system will act corectly its and every time .
    But at list i did a good step on the corect direction.

  • 870A-G54 - power management issues

    A power-management issue with standby. I've set standby to be "S3" in the BIOS - the system goes into standby fine and wakes up fine.
    The problem is, if the system is in standby for a few hours, at some point during that time, it turns itself off fully. As in, powered-down-pressing-the-power-button-causes-the-system-to-boot-from-scratch "fully off". This has happened three times so far (every time I've left the system on standby for a long period). This happens whether the BIOS "EuP 2013" setting is enabled or disabled.
    The duration of time is less than 4hrs, though I don't know what the cutoff is exactly.
    No power-cuts. ;-)
    Any suggestions? I don't know much about ACPI (had to look up what to set the "standby" to in the first place).
    MSI 870A-G54
    Athlon II x3 450
    Powercool 1gb AMD 5670 gfx
    2*2gb RAM
    Antec Earthwatts 380 Green PSU
    500GB Samsung HDD
    Windows XP SP3 32 bit
    NOT over/underclocked in any way.

    Right, I've been conducting some experiments to try and narrow this down.
    With the New powersupply (the Antec 380 Earthwatts):
    - S1 standby works fine.
    - S3 standby works for 12-13 minutes. After that the blinking-power-led stops blinking. If at this point I press the power-button, the computer does NOT turn on. It remains completely unresponsive. I have to wait about 2 more minutes before the power button starts responding, at which point I am booting from scratch (BIOS).
    With the Old powersupply, a non-brand (It says "COLORSit") 400w affair that's known-good.
    - S1 standby works fine.
    - S3 standby does not work at all. The system is powered-off but actually turns off fully rather than into standby. No flashing power-LED. Pressing the power button results in booting from scratch (BIOS).
    This old-powersupply was tested with the EuP 2013 both enabled and disabled.
    For both experiments the dvd-drive was disconnected, so we can rule that out too (though it was never really a contender. :-) )
    Given this, I'm inclined to rule out the powersupply as a cause - this is a years-old power-supply that I've never had a problem with.
    Anyone have any thoughts? I'm leaning towards motherboard, but standby isn't something I know much about, so I defer to the board for suggestions.

  • X200 Power Management Issue

    Hello Everyone,
    First time posting here in the Lenovo Community, hoping some of you can provide guidance.
    When we place any of these computers into Standby Mode, they will succesfully enter Standby.  The next time we try to enter standby mode, they will not enter, it will simply hang.  The only way we can successfully enter Standby again is if we reboot the machine.
    So, long story short, the laptop will only go into standby after a reboot. 
    We use System Center Configuration Manager to deploy our X200, T400 and W500 laptops.  We used to be running X61, T61 and T61p's, and never had this issue.  All drivers are up to date and we're running XP.
    Is there any trick to getting standby to run properly?  We have the Power management driver, Power Manager and the System interface driver installed.
    Any desktop deployment people have any luck with this?
    Thanks,
    Sean

  • Power Manager issues at Windows startup and launching PWMUI.EXE

    Hello everybody.
    I looked up the forum, but did not find appropriate solutions.
    My OS is MS XP Professional SP3 with the lates updates from MS. And I have 2 issues (seems like interrelated)
    Issue-1. An exception occurs on Windows startup: 
    “RUNDLL: An exception occurred while trying to run “C:\PROGRA~1\ThinkPad\UTILIT~1\PWRMGTR.DLL, PwrMgrBkGndMonitor””. 
    After pressing “OK”:
    “.NET-BroadcastEventWindow.2.0.0.0.6e8caf.0: rundll32.exe – Application Error: The instruction at “0x783a3457” referenced memory at “0x10069de4”. The memory could not be “read””.
    After pressing “OK” following message says that DLL can not be executed or something like that, to send error report to MS.
    Issue-2. Power Manager does not launch
    When I press Fn+F3 combination, and click “Manage Settings …”, error messages appears:
    “Power Manager: Power Manager has encountered a problem and needs to close. We are sorry for the inconvenience”. The same situation if I launch “C:\Program Files\ThinkPad\Utilities PWMUI.EXE” directly.
    Re-installation doesn’t help.
    Current version of Power Manager is 1.0.0.0. However , it offered to download another version 1.3.5 (or something like that) via ThinkVantage System Update.
    Thank you in advance!
    Solved!
    Go to Solution.

    Thank you very much.
    I tried so: 1) uninstall Power Manger (+ ThinkPad PM Driver), 2) launch Cleaner, 3) download and install PM ver 1.89.
    The first Windows start was without initial error. I tried to launch PM from Start menu, previous (well known) error message appeared.
    After I rebooted, all started from the beginning…
    Then I restored my old (shipped from the factory) PM from “C:\SWTOOLS\DRIVERS\PWRMGR”. I saw something strange on the monitor: some windows were with new User Interface, some with old one. “About…” command didn’t respond.
    I launched ThinkVantage System Update again. It offered to install new version of PM (in Recommended updated tab) and PM Driver (in Optional updated tab).
    After acceptation, installation and restart everything started to work!
    To sum up I guess that the root cause was obsolete Driver and System Update utility does not check for driver update (only is absent). Practical evidence says so.
    However, now in Advanced mode I have only one Power Scheme: “Timers Off (Presentation)”, in contrast I had several ones in previous version of PM (Energy Star, Maximum Performance, Maximum Battery Life, Source Power Optimized and Timers Off). Is it normal for PM ver 1.89? When I had updated my XP up to SP3, and firstly installed new version of PM, I saw “Video Playback” mode in “Choose Power Scheme” window. Then my PM  broken down.
    Of course, it is not so critical for my work, but when you use ThinkPad you always except flatness in HW and SW operation…
    Thank you again.

  • X200 power management issue - excessive battery drain

    I've been having a bit of an issue for some time with my X200 that I'm hoping somone may be able to offfer some insight on.  My 9 cell battery only gives about 6 hours on a full charge.  The laptop is about 5 months old, but the battery is in good shape (82kwh out of 84kwh capacity).
    On an initial startup the power usage is normal, hovering at around 7-8 watts (looking at the Battery tab wattage in Power Manager). This level roughly maintains even if i am doing light tasks.  This strikes me as normal, and would give the regular nine or ten hours of battery life I had when i first got the computer.
    However, if I allow the computer to either sleep or hibernate, even a few minutes after resume the power consumption (AT IDLING, nothing open) rises to an idling pace of about 11-12 watts. This doesn't go back down to the pre-sleep/hibernate levels, ever (until a restart).  The 25% or so increase in power consuption after sleep/hibernate happens regardless of which power profile I'm in (though the above usage #'s assume I'm in max battery mode with 4 bars of screeen brightness os so).
    This means that 25% or so more power is being consumed after the computer resumes from sleep or hibernate, with a corresponding drop in battery life.  Can anyone offer some insight on why this might be, ways I might go about trying to figure out where the excesssive power onsumption comes from, and/ or possible fixes?

  • Dynadock power management issue

    I have a Dynadock which I connected with another equiptment using the serial port.
    The connection was fine in the begining (after start up) but it is lost after my laptop is in active for a while.
    Once I undock and redock the Dynadock, the connect is back again.
    I've already disabled the power management option of the laptop (Always ON) but the issue persist.
    Question: Is there anyway I can disable the power management feature of the Dynadock?

  • MacBook Pro Power Management Issues and "Broken" Bootcamp

    This is not a question but rather a solution I have discovered to a problem I have experienced many times now.
    My Core 2 Duo 15" MacBook Pro (non-LED version) has exhibited several issues with the systems power management hardware.
    Firstly: Occasionally the system will refuse to turn on. This has happened to me twice, it usually happens when I am running on just batteries. The very first time it happened I was in a meeting and had important data I had to get from the laptop, I was silently panicking. After swearing at my new 2.5 grand pride and joy, I happened to read an old support article relating to older PowerBooks which exhibited the same problems. Apple recommended taking the battery out and then holding the power button for several seconds and then reinserting the battery. This apparently resets the power management hardware feature -- and it worked, and has worked three times since.
    Secondly: I have had a persistent problem when running Bootcamp. Sometimes the machine doesn’t go to sleep properly and although it everything looks right it continues to run (and perhaps, like me, you’ve backed it away in your bag and hence didnt notice it burning up. What has happened to me several times is that it literally "breaks" Windows XP. When you wake the computer or turn it back on (if the battery drained) then youll find Windows running PAINFULLY slow. If you press CTRL-ALT-DELETE (to bring up the task manager) I would see that the CPU is working very hard (at nearly full utilization) and it is so occupied that it won’t respond to anything I do at all. No matter what I did (I attempted a system restore, which was a two hour task with the computer running in its "broken" state) nothing would bring windows back to life. The first two times this occurred I was devastated because the only thing left for me to try was to remove the windows partition and install it fresh (thus losing all my files and settings -- although for the record you can still access the windows partitions files through Mac OS X). This ruined a near full day for me each time the computer did this (having a lot of settings and tweaks and installed programs to reapply). The third time this happened I did the "trick" listed above and reset the MacBook Pro's power management hardware. this has solved the problem ever since (two additional times now). I post this in case someone experiencing the same issue searches the forum.
    I dont know the technical explanation but obviously there is an issue within this series of MacBook Pro's power management. Perhaps it relates to the "artificial" BIOS the system presents to windows through Apple's EFI system (Windows requires legacy BIOS to operate and all Intel Macs alternatively use EFI, so an extra "trick" had to be added by Apple for Windows to be compatible).

    The computer. If two different batteries behave the same way it gives credence to possible issues with the power manager. You can try resetting it with:
    http://docs.info.apple.com/article.html?artnum=303319
    And verifying the firmware is up to date:
    http://docs.info.apple.com/article.html?artnum=303880
    And running the hardware test:
    http://docs.info.apple.com/article.html?artnum=303081
    If nothing seems to help, call AppleCare again, and tell them the battery replacement did not solve the problem and that you tried the above and tell them the results you got.

  • Power Management Issues with Windows 8.1 RTM on HP Elitebook 8560w

    Installed Windows 8.1 RTM on my HP Elitebook 8560w yesterday and am having the same problem as with Windows 8.1 Preview before - power management is not working correctly. The screen will dim real shortly and come right back after the set amount of minutes, but it does not turn off. Standby never occurs. I have the power managent plan set to "balanced", but neither plugged in or on battery do the set timers work. The only thing that works is manually pressing the power button to go into standby.
    Anybody else see this problem or is there a bug fix for this?

    Windows 8.1 is not an official release, and still a beta program and not officially supported.  Also, your EliteBook is a Business model.  Your future issues would be best answered on the HP Enterprise Business Community Forum
    Good luck!

  • Power managment issue ?

    Hello everyone , i'm actually using an MSI 560 Ti Hawk , after the 285.62 update i started facing the famous TDR while browsing with firefox.
    It seems that removing hardware accelleration fixed it .
    I also tried changing the power managment option in the nvidia control panel.. here is my question :
    i moved it to prefer max performance from adaptive ( both in global and firefox specific ) , but i can't see any difference from the standard behaviour , the core is still sitting at 50 mhz
    shouldn't it move up to max core ( 950 ) with this option ?
    thx in advance

    Nope, you have to ask Nvidia about it.
    285.62 think was having such fix for IE browsers.
    You can reisntall them, but remove any VGA drivers 1st in Safe Mode with >>Driver Sweeper<<
    and also when installing the new one, choose custom install and chechmark "Clean Install"

  • IBook won't power on... power management issues?

    Hey everyone,
    _MY SYSTEM_
    I've got a 12" iBook G4 (1.33 GHz) running 10.4.10 that's about a year and a half old. It's been a great computer for me, and I've used it on an almost daily basis since I first got it. Its experienced a few power-related quirks within the last month or so, however. I can't think of any event that would've caused them.
    _THE SYMPTOMS_
    I first started noticing that OS X sometimes displayed the low battery warning at odd times or not at all. I didn't think much of it... figured it could be my power adapter coming unplugged or something. Then I started noticing decreased battery life, but I chalked it up to the effect of fairly heavy use and lots of charge cycles. I continued to feel like my power adapter was getting progressively more finicky... it started requiring much closer contact with my iBook than it used to, but since it's a friction fit, I figured the contact was just getting looser.
    _CURRENT STATUS_
    When I turned the computer on this morning and plugged in the charger the status bar icon didn't seem to recognize it as attached to the adapter. The colored ring around the connection point would go green when connected, but never turn amber. So I used it today until it went to sleep on me. Tried plugging the adapter in, but the same issue existed... the ring would turn green but never amber and the iBook wouldn't actually charge.
    TROUBLESHOOTING
    I first tried another adapter with no luck. I was able to use the power button to shut my iBook down with the intent to reset the power management unit on startup. That key combo didn't even produce a startup, it just killed the adapter's indicator light for a brief moment. Unfortunately the battery seemed too depleted to start the computer back up. I tried zapping the pram, and that got me to the login screen before the computer recognized it was low on power and went back to sleep.
    SUMMARY
    As far as I can tell, the computer isn't recognizing either adapter when one is attached. The battery doesn't seem to be the issue. My iBook is completely unresponsive without the battery (only on AC power), and doesn't charge the battery when both are connected. Anyone have suggestions for me before I make the trek to the nearest Apple store?
    Thanks,
    Matt

    If the power adapter seems looser when you plug it in, you might have a problem with your DC In Board. This is what the power adapter plugs into, and it can become damaged.
    You can go to http://www.ifixit.com/ and look up the DC In Board for your iBook and see what it might take to fix it yourself. If you go to the Apple Store, have them take a look at it.
    Good luck!
