hi Reichtofer,
 
Thanks for Posting!
 
Try opening Control Panel / Uninstall a program and uninstall the Lenovo Energy Management / Power Management Software,
   Restart the system if prompted.
 
 
Now download and install this
     Lenovo Power Management Driver  
 
If  after the installation you were able to see a shortcut icon on your desktop,
    try navigating Crogram Files or Program Files x86 
            now look for Lenovo Folder and It shouldbe located there.
 
Hope this helps
Cheers!

Hi All, I've been trying to get my blue Fn keys to work on my recently purchased SL500.  Volume and screen brightness keys work (but no on-screen display), however Fn+F3 & F5 do nothing, same with the blue ThinkVantage button.  I've installed the drivers via System Update, however each time I get the message "Package did not install - ThinkPad Power Management Driver for SL Series".  The version number is 1.44. Power Manager is installed and running but the driver is not listed under Program & Features.   I'm guessing the lack of this driver is the problem.  Anyone else seen this or have a fix ?  Thanks.

I was missing a driver for an Unknown Device, and the Hardware ID showed up as:

ACPI\PNP0700
*PNP0700

It's parent device was the Intel 82801EB LPC Interface Controller. So I figured I was missing the Power Management Controller. I look in the drivers included with Vista and all that was on hand was the Intel 82371EB Power Management Controller. I attempted to use this driver, and there are no errors, but I really don't think that's correct.

Interestingly, my last Vista installation did not exhibit this issue. I wonder if anyone who has an HP xw8200 (with ANY OS installed) can tell me what driver is used for this device (most likely the power management controller).

Any assistance is GREATLY appreciated. Thanks.

i tried fixing it with a Microsoft support agent before and with the remote desktop help, Cortana had a problem too he fixed it, but the driver he said the there is nothing we could do about it because it's just an incompatible update and that we should just wait for the correct update to come in.Ever since then my laptop do crazy things on sleep, hibernate and shutdown, so i was only finding some workarounds the problem, the sleep mode when it wake up it restart so i switched to hibernating, the new things happens now when i shut down it, it opens weird now like, the keyboard lights up then lights down and the power bottom the same, then either they just stop and i have to hit the power button again or they lights of for seconds and everything runs normalNow i just experiened a bluescreen restart because of it, anyone could advise me on a solution?RegardsNada

I have my lenovo x230 laptop set to sleep when I close the lid. When I close the lid the "sleep" icon on the back of the screen lights up. But the batter will not last through the night on sleep mode. Within five hours or so, the battery is completely drained and I have to plug in and boot up the system. I've never seen such poor batter performance during sleep mode on any other laptop I've ever owned.  Another thread in this forum blames the USB port that allows you to charge mobile phones/etc. during low-power states and recommends disabling the "always power on" option fo this USB port in the Bios settings. I've done so, be it doesn't seem to have helped. At least my laptop still will not make it through the night in sleep mode.  At this point, it seems my ownly option is to use sleep mode only when the laptop is plugged in and hibernation mode when on batter power, which is disappointing. I've never had to worry about this in the past with other laptops.  Perhaps/probably related is the fact that the lenovo ThinkVantage Power Manager (v. 7.16) hangs at the splash screen when I try to open it, so I've been trying to manage the power through the windows control panel power settings.

Hi. If i change in Windows 10 in Power Management from Balanced to Power Saver is this safe for graphic card?
I change from Balanced to Power Saver and fps in benchmark went from 180fps to 50fps. Is there any hardware related changes due to swap from Balanced to Power Saver ?

A:Windows Power Management - Power Saver - is this safe for graphic card

Power Saver attempts to save power by reducing the CPU’s speed all the time and lowering screen brightness, among other similar settings and that may account for your fps drop when benchmarking. Doesn't sound like a good choice for your purposes.

The link to the faulty download file is here: http://support.lenovo.com/ca/en/products/laptops-and-netbooks/lenovo-y-series-laptops/y40-70-noteboo... I know my battery gauge problem has to do with a driver in the device manager called "Lenovo ACPI-Compliant Virtual Power Controller." Sadly I haven't found a way to disable this thing in Windows 10. If Lenovo has an incompatible driver on their systems, the least they can do is provide software for Windows 10 that will remedy the situation. They've got me running in circles.

Recently we have standardized our computer settings to be 10 minutes of inactivity to turn off screen and 20 minutes of inactivity to sleep. It was really tedious to go to each and every computer change the settings manually.
So i made a batch file to implement the standard settings created in one of the xp machines
"powercfg /export powerStd /file filename.
Now to invoke that batch file a NORMAL account allow in xp to change the powercfg.
When i do runas /u:administrator "powerStd.bat, The power settings are created instead for the administrator user.

Hi all.

I have built a new computer system for my parents and am having some annoying power management problems.

The system specs are:
Asus M4A7TD USB3
Athlon II x4 640
4GB RAM DDR31600
Ati Radeon 4350 1Gb

All drivers and BIOS are up to date.

The annoyances stem from the fact that when the system is powered down from Windows, the machine keeps power through the LAN Port and USB bus, keeping lights on the mouse, keyboard and card reader which is a problem for my parents. I realise that this is normal, and - I believe - so the computer can be woken up?

However, BIOS option for 'wake on LAN/KB/Mouse/USB' etc is all disabled.

There is a setting for energy savings requirement EuP, which when enabled, over rides all other settings, and when this EuP setting is selected and the computer is turned off, all power is switched off, and no lights are left on.

However, if EuP is active, and I set the computer to sleep in Windows 7, there is no way to wake the machine up from sleep other than killing power to the PSU. The power button flashes on and off but does nothing when you press it. Nothing happens with keyboard or mouse action.

However, with EuP disabled, sleep works as it should from Windows.

Is there something I'm missing?

Many thanks.

it is manageable through power management. 

Information exposed to operating system during boot:

Processor 0 in group 0 exposes the following power management capabilities:
Idle state type: ACPI Idle (C) States (1 state(s))
Performance state type: ACPI Performance (P) / Throttle (T) States
Nominal Frequency (MHz): 1300

Is this conervation mode? Why isn't the laptop fully charging?

I've recently upgraded from windows vista home to windows 7 ultimate. I've experienced some issues with "sudden" and "random" display closures. To put it simply, the screen goes black (not completely, there's still a slight glow of grey as opposed to completely shut off) and I cannot see my mouse or anything. If i try to input a key stroke, a sound sometimes appears. I've adjusted my power settings to not turn off in ANY situation and the problem still persists.

Then I tried changing the "Processor power management" and changed maximum to 5% (minimum is also 5% originally) as opposed to 100% in the default setting. This seemed to fixed the constant sudden and random black screens but I'm afraid this has decreased my laptop's performance.

These are the specs and I hope someone can tell me what was wrong and how I can go back to a high performance setting without experiencing sudden screen outages.

A:Windows 7 : Black Screen + Processor power management

Is this a laptop for desktop? Sounds like overheating on the video. Vista is getting old so have you ever cleaned the machine? Use compressed air to do the cleaning.

Anyone else with some ideas?

I recently built a new computer (Intel mobo, Core 2 Duo quad-core, 4GB RAM) and installed the Windows 7 beta (32-bit).

One issue that I have observed seems to be related to power management. After about a half-hour of non-use, the computer seems to go into sleep mode. The screen shuts down, all the fans stop, and the hard drive and power lights go out. It then sits there for about a minute like this, and then, for no reason that I can see, it powers back up again. The fans rev up, the lights come on, the screen takes on a glow (though nothing is displayed), etc.

After a few minutes, it powers down again. After another minute, it powers back up. This cycle seems to go on indefinitely.

Does anone have any idea what might be causing this or what I might do to determine what the problem is? I have never seen anything like this before.

Thanks!

A:Strange Windows 7 beta power management issue...

It could be one of your peripherals waking the computer from sleep.
Check the setting of anything you have that could wake the computer up!

Looking for a new driver if you happen to have some time.  I found all of them except 1.  I'm looking for a PCI System Management Bus driver for an IBM T23 laptop running windows 98.  Not sure what info you need to help you out.
