Lenovo T400 / T500 :: Power Manager Alerts That 65w AC Adapter Is Giving Not Enough Power
Oct 23, 2013
I have just installed an i7 2670Qm on my T420 today.The machine will crash pretty soon after booting up, with the screen having colorful vertical and horizontal lines before it restarts itself and give the memory error beeping pattern (1 beep-pause-3 beeps-3 beeps-pause-1 beep).So then I took out one RAM from the bottom, and the machine appears to work normally again, more or less.
In the OS (Win7 64), The power manager alerts me that the 65w AC adapter is giving not enough power, so the laptop is running on battery. I thought I just need a 90W AC brick so the laptop will work as it should, so I am arranging a 90w one to come in later. But on a second thought, if the battery cannot start the laptop with 8GB of RAM properly.
Is it the CPU or RAM or Mobo or something else? Where should I look?The machine works fine with the previous CPU i3-2310m and 8GB of RAM.The RAM modules I have are 2 x 4GB Samsung 2Rx8 PC3-12800S-11-11-F3.The BIOS version is updated to the latest 1.46.

I enjoy the feature of automatically powering off the optical drive in power manager. My issue is after reformatting my T530 the option is there until I do an update using the Lenovo ThinkVantage System Update. One of the updates seems to remove the feature from the power manager.

I has just upgraded my Thinkpad t440 from windows 7 to Windows 8.1 pro. But i could not find Power Manager software to install in my laptop. I want this software to manage my battery to ensure that it stop charging when 80% capacity. I think that it is useful for my battery.

I have a T430s with Windows 7 Pro 64-bit that is not entering 30 Day Standby like it should. The issue seems to lie with Power Manager.
Inside of Power Manager I have the 30 Day Standby option checked, just like I should, and it is also reflected in the BIOS setup as well. If I change the BIOS transition time for 30 Day Standby to "Immediately" and start Windows, but don't log in, and put the computer to sleep. It almost immediately wakes up and transitions into 30-day standby.
Now I know that Power Manager has a "hard coded" setting of 3 hours, regardless of the BIOS setting. So after 3 hours, Power Manager will automatically wake up the computer like it would to transfer to 30-day standby, but it just goes back to normal sleep.
Today while on battery, it did this twice (according to the Windows Event Log) Wake up, and go back to Sleep / Standby (S3). In the logs, the wake source is listed as "Unknown" when it goes back to sleep 10 or so seconds later is listed as "Application API".
Like I said, I was running on battery, and I also went into device manager and unchecked anything I could think of that would have an option of "Allow this device to wake the computer". I also disabled the Wake-on-LAN option for the LAN card. Plus I had all USB devices unplugged, as well as no Ethernet cable in the LAN port anyway. Plus it does transition to the 30-Day standby if I force the computer to sleep at the login screen before Power Manager is loaded.
I just wanted to add I should have all driver / software updates as of Dec. 1 or so. I'm running Power Manager 6.63.1 and Power Management Driver 1.67.4.4.

I can't adjust my screen brightness using the Power Manager. Updating to the latest release of the ThinkVantage Communications Utility did not solve the issue. I can't make the screen either brighter or dimmer.

I recently my new Thinkpad T530 and I accidentally uninstalled Power Manager. I re-installed it. Now when ever I log on It says, "RUNDLL: There was a problem starting C:/Program. The specified module could not be found." And whenever I turn on the icon in the taskbar it is gray and has three dashes.

I have a refurbished T410 that words fine and charges the battery when plugged in. When I remove the power ca ble, it dies immediately. The battery shows fully charged, but will not turn on unless the power cable is plugged in.

I have three drives: mSSD, HDD, HDD in ultrabay. I think this is taking its toll on my battery. My first HDD is often used since it has my "DownloadsFirefox & uTorrent" folders. However, my second HDD only has music. Is there a way to have it automatically power-off when I don't play music from that drive?

I'm tried hard-booting the device, but no dice. When I push the power button, I show activity in the status lights and can feel heat coming out of the heatsink. I think I see the 'ThinkPad' screen displaying very faintly at that time, but it seems not to proceed through the regular boot process. I'm definitely not able to get to a BIOS post.

My T420 doesn't power on at all. I have tried to turn it on with cable, w/o cable, different baterries, removed rams and tried same things, tried holding down power button for 60 secs, tried with an other keyboard and I couldn't manage to start the laptop. No reaction at all, no blinking or anything.

Symptoms: Laptop switches off unexpectedly; unexpected failure to charge battery; random changes in brightness. Messages appear such as: "This AC adapter may not provide enough power to your Lenovo computer. Please reconnect the proper AC adapter"; "Battery 2: There is an error"; Do you want to switch to 'Airplane in-seat power plan' (if this option is enabled in Power Manager).
This is why I think the power connector is to blame: I opened Power Manager to the Battery tab and also ran BatteryInfoView by Nirsoft. With the power connector firmly plugged in at the back of the laptop and with "90W AC adapter is attached" showing in PM, moving the connector slightly from side to side often triggers one of the symptoms. The two apps then indicate that the AC adapter is no longer present and that charging has stopped. In some cases vibration due to typing or moving the laptop is enough to trigger a symptom.
Supporting evidence: After I taped the power adapter's output cable to the laptop so the plug cannot easily move in its receptacle I found the symptoms stopped (see photo).
Summary:This is a serious annoyance. It means I can't rely on the battery being properly charged when I need it, or that the machine will stay running when I leave it unattended.

I have recently bought a T400. At the moment, it is running on Windows XP, Service Pack 3.
After installation of Windows XP, I have installed all the relevant drivers and no yellow question marks appear in the Device Manager panel. However, during the process of installing these drivers, now whenever I plug in our take out the AC Power Plug, the screen goes blank for about a second and then comes back.
This problem was NOT there immediately after installing Windows XP and Service Pack 3, i.e. before installing the drivers. I think that it is one particular driver which may have caused this.
I have already tried re-installing the Graphic Driver.

My thinkpad T410 (2537-UQF) with an OCZ Vertex 3 SSD only boots if the power supply is plugged in. If i have full battery and try to boot without the power supply i get a blue screen after being about 60 seconds in the screen where the windows logo appears. I have Windows 7 installed fresh a few days ago.
I think its possible, that i have made some failure with the drivers. The ThinkPad Power Managers always stops working after booting. So i have removed the program by using the "msconfig" functionality.

I'm experiencing regular BSODs on my T430s / Win7 when going into sleep mode (Fn-F4). The error message is driver_power_state_failure. This happens almost every day.
I know this is quite a common issue (I also had it with an older T500, but not on T420). After googling around, I've discovered WinDBG and the way to identify the faulty driver that is causing the problem.
However, I couldn't install the tool - neither the debuggers package (referenced from windbg.org), nor the toolset+.NET framework from the Microsoft website. The former keeps exiting the installer without any messages (although Remove Programs dialogue shows the thing installed, there appears to be no program to run), the latter fails to install without any diagnostics (tried installing debugging tools only, tried installing the complete package - same outcome).
So, need to analyzing the memory dump and identifying the faulty driver? Which file is needed for that - the complete memory dump (from /Windows/ folder, ~500 MB in size) or the minidump file (from /Windows/Minidump/ folder, ~700 KB in size)? Or both?

I've been trying to set-up a second hand T520 bought without the original hard drive. I've installed a Samsung mSATA SSD. I tried to use a set of recovery discs produced on my T510 which seemed to install but got BSOD whenever Win 7 tried to boot. I then downloaded the Win 7 ISO and booted from the DVD to try and initialise a repair which would not initialise. I next tried installing Win 7 Pro from the Win7 ISO disc which succeeded but ran into problems with unrecognised network components and drivers.
I've gone through this whole cycle again and got to the set-up screen for Win 7 then got distracted; my thinkpad then appeared to have gone into hibernation before I could finish set-up. Unfortunately, when I try to power up I get a few flashing lights for a few seconds; no POST bleep and the power dies. I've tried pulling and reinstalling the RAM and SSD but to no avail.

I had an admin power on password on a T420 that contained a character that isn't allowed in the newer version (old password had a dash - in it) and I didn't remove the password prior to update so now I can't get into the BIOS as admin - are dashes changed to something else during update or can I revert back to a previous bios version (if so where are they located)?

I have a T530 with an SSD, less than a year old, that appears to be bricked ... when the power button is pushed, there is absolutely no noise (no fan, no beeps) and no indicator lights.
I'm having trouble getting the "what happened" story out of the user but I heard something like "the battery ran out and now it won't start". I suspect some improper behavior like hauling the machine around when it was "sleeping" (not off) but that as they say is another story.
Elsenet I saw the following "one weird tip" to discharge static buildup (*)
* unplug power
* take out battery
* take out RAM
then a sequence where you pushed the power button 9x and on the 10th time held it for 30 seconds. Then plug power in and try again. No soap (although the ram is internal, not in the expansion slot, so I haven't disassembled the keyboard area to check).
I also unplugged the battery/power and held down the power button for one minute - still no luck
Swapped out power supply and battery - no luck
Only indications of "life" are the little battery icon on the top of the case (e.g. when computer is closed):
- Battery not installed - put power cord in, icon flashes green 3x, stops, but power button does not turn on
- Battery installed - put power cord in, icon flashes green 3x, flashes long orange 1x, flashes short green 1x more
Is there something else I can try or is this a "Call IBM/Get this guy a loaner"?
* laptop appears to be staticy, I have gotten a couple of "snaps" off it, and that doesn't regularly happen

I just got my ThinkPad T530. Things are going ok with it, the keyboard isn't as terrible as I had thought - but certainly didn't wow me like the keyboard on my T510 which I think was the best keyboard any ThinkPad ever had.
Anyway, something I have noticed, and that is sort of a problem for me, is that this computer is not making the typical "power status change" beeps that every other ThinkPad has ever made. You know, the dee-dum, dum-dee that go along with plugging or unplugging the AC power adapter. Also no single beep when it finishes going to sleep, or wakes up from sleep.
How I get these back? I didn't see anything obvious in the BIOS or Power Manager.

my Lenovo T410 laptop won't start. I hit the power button and it looks like it's about to boot up. The thinklight blinks on as normal, the cd drive is checked, the caps lock button blinks on, then nothing. No display, and keyboard is unresponsive. Power light remains on; if I leave it a while the fan comes on. I can turn the machine off using the power button, but the problem remains next time I switch it on.
I've tried removing power and battery, pressing power button 10 times then holding power for 30 secs, before replacing power and battery, but nothing happens. I've tried using a different keyboard. I've tried plugging in an external monitor. No change.
This problem appeared after I left it on overnight. I have a hunch that it went into hibernation mode, perhaps, and that it disrupted some important function which it was unable to complete.

My T420 takes about 20 seconds from pushing the power on button to the Lenovo POST screen. After that boot takes about 30 seconds to Desktop. What bothers me is this long wait until I see the POST screen. It doesn't seem normal to me.
My System is setup with Windows 7 64bit booting from UEFI on a mSATA Crucial M500 SSD. It has 16GB of Ram and a i7 CPU. I have the newest BIOS (1.46) installed.
Why it takes this long to reach the POST screen?

I recently bought a Thinkpad 540p and wanted to know a way for stopping the battery from getting charged after a certain level. Its a very common feature to stop a battery from charging say after 80% and run on AC power supply directly.
Other lenovo laptops do support it, under various apps like Energy Manager, or Power Manager but I am not able to find any such options/app on my laptop?

I'm using Windows 8.1 on a t431s. I'm having this problem where none of my external storage is being recognized. Under "Device Manager" any sort of external storage I plug in ends up under "Other devices". When I click on the device, I get Code 28 "The drivers for this device are not installed." Trying to update the driver brings me nowhere. The devices don't appear under disk management.
What's weird is that other USB peripherals such as mice and USB headphones don't have any problem.
Here's what I've tried so far:
Updated the BIOS.
Used Lenovo's SCCM package for Windows 8.1
Tried installing the individual drivers for each hard drive.
Nothing works!

Our Studio 1749 will retain a solid connection when the power adapter is plugged into the power board along the side of my laptop. I am unsure if the pins residing in the power board are pushed toward each other so as to not retain connection when the adpater in plugged into the laptop.

Just upgraded and installed the ASUS RT-AC68U router. Installation was smooth with no issue. I have the T440s laptop running Windows 8.1 with the "Intel Dual Band Wireless-AC 7260" adapter and I checked the device manager > wireless mode and still shows 6.802.11a/b/g. Should AC be included in this mode? How can I update the adapter to AC mode?

I'm not sure if any other user has experience this issue. I did a lenovo update couple weeks back and since then my wireless adapter would not work after waking up from sleep mode. It shows that the wireless adapter is connected to wireless network but the internet would not work. The only way i can make it work is by disabling the wifi adapter by putting the laptop in airplane mode and then bringing it back out from it. Disabling and enabling the wireless adapter does a quick fix and does allow me to use the internet without any issue for the time being. i have also uninstalled and reinstalled fresh drivers from lenovo website, still having the same problem.
