I left my T400 on overnight running on battery (clearly not the brightest idea), and now it won't start up. The plug and battery lights do illuminate when I plug it into an outlet; when I turn it on, the num lock and caps lock lights illuminate briefly, and the power status indicator light illuminates. It makes a few whirring noises, and then just sits there. !

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.

I found a t500 in my basement without a battery or adapter, however i am not sure if it works or not, so i was wondering if i could just buy the adapter to see if it boots up or not because i don't want to go through the process of returning etc.

System update Lenovo stopped working some days ago. Today I had my fingers crossed that maybe with the installation of currently latest version it will work (systemupdate506-11-04-2014.exe). When I have ran the installation it has warned me there are some previous versions and it will be installed, but installation didn't went thru. After manually removing System update service (sc delete SERVICENAME) and running the installation again, the installation wizard completed successfully...
But then when I run System update I receive an error "T440S - System update Cuuldn't start properly".
How to achieve that System update would work properly on T440s laptop. My operating system is 8.1 x64 enterprise.
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.
I've got a problem with the laptop Lenovo T410s. I've put the new HDD on it (tried even the same with a different HDD too), and started to instal WIN 7 64-bit from the recovery disks. I used to do it many times so far with different Lenovo laptops without any problems. But this time, a while before the end of the instalation (when processing the sdrivebackup.wim) it stops and comes with a statement: " the recovery process has been finished, please ...." (but I see that the progres bar is far awayfrom 100%) , and finishes the instalation, reboot the computer and it comes the screen with the statement from the Windows Boot Manager:
"Windows failed to start. A recent hardware or software change might be the cause. To fix the problem (...)
File: Windowssystem32winload.exe
Status: 0xc000000f
Info: The selected entrycould not be loaded because the application is missing or corrupt"
I read a lot about the ways to solve similar problems, but they don't work on my case. The strange thing is, that I can instal WIN 8 or WIN7 from regular Windows instalation disks (not from Lenovo recovery, but from normal universal Windows instalation disks).
As I told before, I tried it in 2 different HDD disks with the same effect. It looks that the recovery instalation stops before the end without instaling some files which are missing later during starting the system.
I do have Lenovo Power manager icon on the taskbar, so I can monitor the battery charge. However, if I forget to watch the icon, the laptop goes into hibernation unexpectedly. Is there a way to enable a visual alarm like an pop-up icon which would remind of low battery?

For some reason, but seemingly all of a sudden, when I plug my T530 in, the battery does not charge. When I move my cursor over the "power" icon in desktop mode, the message "Plugged in, not charging" appears. How do I alter this, so that I may charge my battery?

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 have a video about this Thinkpad 410s.I always pull the battery to replace a screen on a laptop.After replacing the screen I got ready to test it.I forgot to repace the battery and with the power adapter NOT connected it booted once before I realized what it was doing.I then turned my smartphone camcorder on and it booted a second time.Is there a second battery or is it running on capacitors? it had been unplugged 3 days before I changed the screen.
View 2 Replies View RelatedI have a T420 with Windows 7 SP1. I bought a replacement battery of 0A36303 (ThinkPad Battery 70++ (9 cell)) and got one with a new Replacement part number (FRU) of 45N1007 (it is clearly written on the battery alongside “ASM P/N 45N1006”).
[URL] .....
After I installed it in the laptop and made sure to run System Update and update all the Lenovo software to its latest versions.
I also run the Lenovo Battery Firmware update utility, which informed me that the battery has the latest firmware (0003-0080-0100-0165). [URL] .....
When I run “Power Manager” (latest version, 6.66.3) and choose the tab of “Battery” I have this mismatch data:
Both “Design Capacity” and “Full Charge Capacity” shows "90.00 Wh" which almost fits the characteristics of the 0A36303 battery (as detailed at [URL] .....) which is "94 Wh" (in compare with "57 Wh" for the 0A36302 model, detailed on the same web page mentioned above)
But the “FRU part number” field says “45N1001” which fits the “0A36302” model… (as detailed at [URL] ....)
Why is this mismatch?
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've owned a ThinkPad T430 for about one year now. Originally I was fairly impressed with the battery life (around 4.5 hours) but now after owning it for a year I am very unimpressed with it's short 3 hour life now.
I have read that batteries should be expected to do this, although I have friends with a MacBook Pro which has lost maybe 20% of it's charge over three years not one year like my ThinkPad!
My specs are listed below:
OS: Windows 8 (upgraded from 7)
Ram: 8GB (4*2 DIMM - came with 4GB and I upgrade it with 4 more)
CPU: i5-3210M 2.5GHZ
Hard Drive: Samsung 840 Pro 256GB SSD (upgraded from the 320GB 7200RPM HDD before...if I have got those specs right)
I recently installed the new SSD and expected to see my battery life shoot up again (hopefully at least half an hour) but I really haven't noticed any such improvement.
I use the battery frequently for school and run the battery down to about 20% maybe twice a week on school weeks?
Is this kind of deterioration to be expected and should I simply purchase a new battery if I need that extra 1.5 hours?
According to the Windows 8 battery report the original full charge capacity was: 49,286 mWh, now it is: 39,780 mWh.
I use a T440 with WIN8.1 pro machine but for whatever reason the external battery has stopped charging. As this laptop is only 3 months old Lenovo send me a brand new one but the outcome was the same, the charge symbol comes up on my screen when rebooting the machine and shortly after stops completely. I have now had my internal battery pack changed and again no improvement.

View 7 Replies View RelatedI just got my T440s a couple of weeks ago. I stupidly ordered it with only 4GB of RAM, thinking that I couple upgrade it myself if neccessary (and it would be much cheaper that way).
Well it seems 4GB definately isn't enough for my needs, so I ordered another 4GB stick. I installed it, plugged the machine in and powered it up. And was met with the tone for a memory error. Probably the module isn't seated correctly, but I suppose it could be faulty.
Anyway, you'll notice I said that I plugged it in before powering up. That means that the internal battery has been reactivated. I can confirm this because it will start (and give me the error) without being plugged in and without the external battery connected. So my problem is, how do I disable the internal battery again to remove or reseat the problem DIMM, since I can't get to the UEFI/BIOS configuration to disable it.
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?

It goes away after I hit ok and the battery appears to still be functioning but the error is super annoying.

Since I have performed a BIOS update to 2.14 and an update of the Intel Wifi driver to 17.0.5, I experience the problem of battery drain when the computer is in S4 sleep state, at a rate of approximately 0.125% per hour (on the 56Wh battery).
This was not the case before these updates. There was no noticable power drain in S4 sleep state, even not over multiple days. I'm using Win7, I set all the WoL capabilities both in BIOS and in the Intel driver to disabled, according to [URL] ....
External device USB charge settings are also fully disabled in BIOS and Power Manager. The problem does not occur when the system is fully shut down, but in S4 Sleep state, which should be a zero-power state too, as it was before the updates. In the details of the BIOS update it is stated " Fixed an issue where the computer might fail to enter sleep state". Could the power drain be a side effect of this fix? Or is it an issue with the (new) Wifi driver, as it was the case for the Y410P?
How could this battery drain be avoided?
Bought a refurb T400 and installed a PNY SSD in it. It POST's okay and I can access bios. I can also read/install Linux from DVD just fine.
Trouble is when I insert my win7 home premium DVD into the drive and boot it, I get POST and then I get a black screen. It seems to be reading the drive and when I interrupt with the Esc key or open the DVD drive, I get a Windows menu explaining that the installation has been interrupted.
I've looked at the bios options and can't see anything obvious that should be changed.
I have tried to make a fresh Windows 7 installation, but after installing updates via Lenovo System Update the system gets corrupt.I replaced the hard drive on an T400 and loaded a image that I had on to the drive. After a installing a few updates and program I noticed strange system beaver. So I did a system file check and it came back that files was corrupt and cold not be repaired.So I did a new fresh Windows install. But it to became corrupt after just running Windows Update and Lenovo System Update.So I ran some hard drive and memory diagnostic without find and problems.
Then I did a new Windows 7 install again. After I installed all recommended updates from Windows Update I did a system file check, all OK. The I installed Lenovo System Update and all its recommended updates and did a new system file check, Windows system files corrupt. What Lenovo update is destroying the system?
