Lenovo T400 / T500 :: T430s Battery Capacity Sudden Drop
Nov 12, 2014
I have a look at my battery report today and found something really awkward. I bought the computer seven months ago, and the battery start with Design capacity 44,000wWh, while the full charge capacity is quite closer to the design capacity. However in the battery report it shows that two weeks ago the design capacity suddenly drop from 44000 to 40734mWh in one week, and then afterwards it drop to 39000mWh. And the actual full charge capacity seems to linger around 37000mWh. Is there something wrong or is my battery just wear out naturally?
Recently my T510 9 cell battery suddenly stopped working. According to the Lenovo battery utility, the battery condition is poor and it suggests replacing a battery.
However, the battery seems still have 99% capacity, either by Lenovo utility or by other softwares. Before the failing it lasts 3-4 hours and charges normally.
I read several posts online and see some people have similar problems. It is suggested that maybe one of the cells fail so the circuit stopped the battery from working/or the safety circuits just malfunctions? Or indeed I need to replace the battery.
I understand that messing with battery is risky and I believe it is detected as not working for a good reason. However, I am wondering if there is a way to assure that my battery is completely dead, but not a problem with other hardware or the OS, before I purchase a new battery. For example, using a volmeter on the whole batteryto see if I can get a reading, or opening up the battery case and test on each cell?
Is it doable to replace a single cell if one of them fails?
PS: For people who says that they connect two terminals of the battery to a volmeter and see no readings, I believe you also need to ground the safety pin to turn on the battery.
I recently upgraded my ThinkPad T430s to Windows 8 Pro and ever since my ultrabay battery gives me an error when ever I restart or turn the machine on. It goes away after I hit ok and the battery appears to still be functioning but the error is super annoying. I have the latest drivers and software from Lenovo and I have already had the battery replaced via tech support. Its so annoying i'm tempted to see if I can just get the whole unit swapped.
When I use the battery as the power of my laptop, it always shutdown abnormally before the battery reach the “critical low battery alarm”.
For example, I set the power manager to sleep when the battery lower than 10%. However, it will out of power when the battery reaches 12-13%. It wasn’t a normal shut down, it suddenly goes down without any alarm. It seems that the power been cut down by someone.
My laptop is a new thinkpad T430s, it seems something wrong with the battery. I try to Perform Reset the battery, but it still not work.
We just bought 15 T430S model N1RLPGE/2356LPG. We install all our notebooks with a running DHCP/PXE environment. A formerly ordered notebook, same type, but an older BIOS (Version 2.02) accurately got itself an IP address during PXE boot and startet the installation. The new T430S (all delivered with BIOS version 2.55) don't even get an IP. I already tried updating the BIOS to the newest version 2.56, but this didn't solve the issue. I checked everything at least twice.
MAC address for IP reservation: correct. Swich (Cisco) portfast is enabled: correct. An older notebook with BIOS 2.02, installing smooth and sound.
When I start the BIOS version 2.56 notebook with a Knoppix DVD, I get the assigned IP address. But not during PXE setup. I also checked the available BIOS and PXE options of the notebook/ethernet card. No options that solved this issue.
I need to do a clean install on a T430s and create an image of it for deploying to other laptops. The rescue CD from Lenovo is a 3 DVD set that installs all the bloatware without an option to install just the OS. How I can get this done?
I wanted to change boot sequence to boot from external DVD drive to install Win8. To access the BIOS I hit Enter (empty password I guess) but in the BIOS everything is greyed out: I can't make any changes. What is going on?
My laptop was running Windows 8.1 with SecureBoot enabled just fine. But I just swapped out my boot drive for a bigger SSD and, when I tried to boot from my USB installation media (to do a fresh Windows 8.1 install), nothing would happen (the screen would just flash when I tried to select the USB drive). I realized I had to disable Secure Boot in order to boot from the USB drive and then to enable booting from legacy/non-UEFI devices.
So now I've been able to install Windows 8.1 and it's running without a hitch, but Secure Boot is still in the disabled state. When I enable it, I can't boot from anything. How can I re-enable Secure Boot with my fresh Windows 8.1 install? Or if I have to reinstall, what steps do I need to take this time?
just got a T430s with i7-3520M processor (3.60 GHz, 4MB L3, 1600MHz FSB) and 8G memory. How do I stream to my HDTV with sound? USB 3.0 to HDMI adapter? MiniDisplay to HDMI? Any caveats I should be aware of?
When I pressed Fn-F5 previously, I had the option to enable/disable Wireless Lan, Bluetooth and Wireless Wan. However after running System Update recently, when the latest Access Connections (5.98) and BIOS (2.52) was installed, I have lost Bluetooth and Wireless Wan!
When I press Fn-F5 now, I only have the option of Wireless Lan.
I have checked the BIOS, and Wireless Lan, Bluetooth and Wireless Wan are Enabled. I have tried setting them to Disabled and then Enabled again but the problem remains.
I even did a factory reset. but I still cannot find Bluetooth and Wireless Wan.
The Wireless Wan adapter can be seen in Device Manager and Network Connections. Using "Diagnose this Connection", the suggestion is to "Turn on mobile broadband capability" & "Use the switch on the front or side of the computer, or use functions keys if available, to turn on mobile broadband capability on this computer."
The hardware wireless switch is turned on but Fn-F5 has no option for Wireless Wan.
Bluetooth is worse; the adapter cannot be found in Device Manager.
I have a T430s and I love it so far, except one negative thing is that it keeps "skipping" around whenever I type. During typing, on random occasions it will skip to wherever the cursor is placed at that moment, often in the middle of a word I had already typed previously. (It has done it 4 times while typing this message) Obviously, this makes it very annoying to have to re-do a word or sentence over and over. I definitely don't type extremely fast and try to be careful with my hand placement, but as a normal sized adult male, can it be possible that the new Chiclet Keyboard makes it easier for my fingers or palm to inadvertantly move or press the touchpad which causes this problem? Or is this a software defect?
This is my second Thinkpad and I've never had this problem before.
I have new T430s with Windows 8 on it (preinstalled by Lenovo). Everything is fine except they cut a huge chunk of my expensive SSD hard drive for so called "recovery partition". So now I have 2 tasks to accomplish:
1. Create recovery media on DVDs; 2. Remove that recovery partition from my HD and attach the space to main partition.
On Windows 7 I would use "Rescue and Recovery 4.5" tool from Lenovo to do that. But it looks like the tool is not available for Windows 8. When (if) it will be available? Or any other way to accomplish the above tasks?
I'm planning to add a mSATA SSD on a brand new T430s and use the 500gb HD for data. I ordered the R&R DVD's so that I don't even have to turn on the machine with the factory drive. I will remove it and install the mSATA to install OS etc.
Then reinstall the factory drive for reformat and add data.
I'd rather do this than go through the whole first time setup with the factory drive just to create R&R disc. It seems like a giant waste of time otherwise.
I'm assuming the factory R&R discs will have the OS, drivers and Thinkpad utilities, which is all in need.
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 188.8.131.52.
My 3 month old t430s has a major issue with the audio/sound. At completely random times, I will have no sound for a matter of minutes or hours. This is primarily with web software and persists across multiple browsers.
- The speakers all test and the troubleshooting tests say they are working just fine. Occasionally, when testing the speakers, the control panel will give an error stating that they are in use by another program and that program needs to be shut down before they can be tested.
- all drivers are up to date and have recently been uninstalled and reinstalled
- the default audio device is set to the appropriate speakers
- I have had this problem with and without the Dolby Advanced Equalizer driver that comes as an optional sound update
- I have had sporadic luck with plugging in headphones, but often this does not give me any audio either.
Well I use my own laptop as a admin/standard user I use my standard user account mostly. I remember on my v570 when the user access control came up i had the option and i could type the password or use the finger print. so i was wonder if their is away i could set that up on the thinkvantage fingerprint software so that when the use access control comes up when i'm on my standard user account i could swipe my finger that i use for my admin.
I have a t430s laptop. my laptop seems to randomly switch programs or at least switch off the current one im working on. when im shifting around in excel or typing in an email. it will deselect the program im running and sometimes it will switch back.
I’ve had the T430s for about a year. Whenever the laptop goes into sleep/hibernate mode, I hear a high pitched hum come from the bottom back section of the laptop. It also becomes noticeably louder when I unplug the AC adapter. I've put my ear to the laptop to try to identify where exactly the noise is coming from. I attached a picture with the general vicinity circled.
I don’t think I explained the issue to the repair centre properly. They ended up replacing the fan the first time I sent it in for repair. The second time I sent it, they replaced the system board. However, it continues to emit that high pitched hum.
Am I being too sensitive to the noise or is this something that can be fixed? I’m just past my warranty and I’m afraid if there is a problem that isn’t identified, I’ll be stuck with it for the next few years.
I have a new T400 (2768GP6) running Windows 7 Enterprise (~3 weeks old). This morning it just turned off all of a sudden and won't turn back on. I tried pressing the power button 10 times and holding it down on the 11th time with no AC or battery connected, but it's just dead. None of the indicators are lit when connected to AC.
I might point out that I did spill some coffee on the keyboard this morning about 5 minutes before it shut off. But, it was barely a few drops (you know, the few drops that remain although the cup is technically empty) and I wiped it all off with a paper towel. Those few drops spilled at the bottom left-hand corner, right by the Fn and Ctrl keys.
During one month usage of my T430s, I met four times of BSOD(Blue Screen) and the recent two showed the same error message: A clock interrupt was not received on a secondary processor within the allocated time interval. And the stop code: 0x000000101
Here is the screen shot:
Link to picture
When I use the software "BlueScreenView" to read the .dmp file, it says that it caused by address "ntoskrnl.exe + 7f1c0".
And recent two days, when I use Vmware workstation 8, the playing music suddenly stuck for few seconds and my screen was freezed. I thought the BSOD coming again, so I stop doing everything with my PC but then the music came back and screen was released. I think maybe the CPU is stucked again but not so serious to cause BSOD. But I treat it as a sign.
By the way, after I got my T430s, I have done lots of stability, stress test, including Prime 95, Furmark, MemTest Pro. But none of them gave me problem and my T430s all survives. But the BSOD just happened randomly.
My Config: i7-3520M with HD4000 8G RAM SSD
I enabled Intel Turbo Boost before recent two BSOD.
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?
My T430s camera(Windows8) is not working now. The LED light is on when I start the camera, but no imamges show up. I checked the driver, and it's already the latest version. The camera was working at the begining when I got my laptop, but I don't know what happened to it.
I just purchased a new T430s and, overall, I've been very happy with it. However, I'm having trouble getting a particular multi-monitor configuration to work.I am trying to get the very first configuration as is described on this page. URL....It is simply a 3-monitor setup where one monitor is external and hooked up via VGA, another monitor is external and hooked up via DisplayPort, and the third monitor is the actual laptop monitor. I simply cannot get this to work! I can plug in a single external monitor, but when I try and plug in a second, it always disables my laptop monitor, so I end up with only a 2-monitor setup.
I've called Lenovo Support 3 times after encountering this problem, and They kept citing that it was a "configuration" issue and that it's not their problem, and then they'd forward me to another department which would then forward me right back to them.
I have a T430s computer model 2352CTO, running Windows 8.1, 64-bit version. Prior to upgrade from Windows 8.0 all drivers were updated. The USB 3 ports worked correctly, in particular running an external 1gb hard drive. After update to 8.1, the USB 3 ports still work, but only for about 30 seconds then the hard drive shuts down. The power light is still lit on the hard drive, but it no longer shows in windows explorer.
In device manager, I went to Universal Serial Bus Controllers -> USB Root Hub ->Properties->(under General it says "This device is working properly)->Power Management->Unchecked the box for "Allow the computer to turn off this device to save power". Unfortunately this does not seem to stop problem.
I got a T430s with the nvidia nvs 5400m and when i try to update drivers etc via the lenovo system update I got a message that I should update the Intel rapid storage driver to 184.108.40.2066, and that isn't even the latest version, but anyway I mark the update and let it install and then reboot. But when I search for updates I have to update the same driver to the same version I just installed. I have tried to remove the driver via device manager, but without results.
best way to install a *clean* version of Windows 8 to their Thinkpad that came with Windows 8?
I ordered a T430s with low specs and Windows 8 and I dropped in an 8GB DIMM and mSATA drive. However, the Lenovo implementation of Windows 8 is maddeningly difficult to create backup media (you can't) and the Lenovo "restore" from the HDD partition won't allow you to restore to another drive. Plus, that kinda defeats my original purpose of a clean install without any bloatware onto a fast, user-installed mSATA or SSD.
I have Windows upgrade media I purchased for my desktop, but that install program says the installation won't work with the Lenovo Product Key specific to my Thinkpad T430s (I'm guessing it's an OEM product key while the install media is an upgrade looking for a previously installed Windows 7?)
