My Laptop is 1 year and 5 months old. There are 2 problems I am facing with my battery:
1) When it is charging, at around 86% level, it stops charging and I see an orange light blinking at the battery icon and it continues to blink unless I turn the power off and allow the battery to discharge for a while.
2) at around 45% to 50% level, the battery level suddenly drops to 7% level and then I have to charge again.
Because of these issues I now use my laptop as a desktop. It is always plugged in and I use the option of "Stop Charging" in the windows power settings. how to solve the problem.

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?

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 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.

I have a two month old Lenovo T540p with win 8.1 and a Realtek 2x2 1 1b/g/n wireless Lan M.2 adaptor that loses the connection to all wifi every 10 minute. The wifi worked fine in the beginning, but after a month and some updates the problem started.
Lan cable works without any problem.
I can always fix the wifi with turning off all wifi ( t. ex. fn+f8) wait 5 seconds and turn it on again. But after aprox. 10 min. it drops out again.
Every part of the laptop is up to date, even bluetooth driver, bios etc..
I tried another router same result. I tried changing channel on the router.
I tried connecting to a hotspot on my smartphone, same result.
The distance to the router makes no difference.
The Laptop is scanned for virus with Avast free.
I use chrome but tried IE and mozilla with the same result.
I tried to ping the router and it receives no data when the connection is lost.
I tried turning the firewall off, same result.
There no power saving on wifi.
Everything is fine in device management
Maybe its a win8 issue ? Do I really have to format the hd turn the computer back to beginning and start all over ? This shouldn't happen to a brand new computer.

I have a fairly new (purchased 8/2013) Lenovo ThinkPad T431s with Windows 8.1 Pro 64-bit. It has a very tricky error coming basically 8 / 10 boots: Windows is Scanning and repairing drive... (see attached image).
Error details from Windows Event Viewer:
A corruption was discovered in the file system structure on volume ?Volume{f62db2cf-efe4-4b55-a3f7-0e7db991a984}.
A file on the volume is no longer reachable from its parent directory. The parent file reference number is 0x2000000000002. The name of the parent directory is "<unable to determine file name>". The parent index attribute is ":$I30:$INDEX_ALLOCATION". The file reference number of the file that needs to be reconnected is 0x400000003db80. There may be additional files on the volume that also need to be reconnected to this parent directory.
What is wrong (my personal analysis): To me, it seems that for some reason there is one (all the Event Viewer details point to similar error) corrupted / missing Windows (System) file that is causing this, but what the file(s) is/are.
Other symptoms on my laptop is that after loggin in and using whatever app (Windows delivered or 3rd party), the whole laptop jams totally for say 30-240 seconds and all apps go to "Not Responding" state untill Laptop recovers AND I can continue using my Laptop "normally".
What has been done trying to fix that:
1) SSD disk has been changed (image from previous SSD copied back) -> no solution, error remains
2) chkdsk /F /R -> no solution, error remains
3) SFC /scannow -> no solution, error remains
4) dism /online /cleanup-image /restorehealth -> no solution, error remains after a few boots
5) TRIED using "Update & Recovery -> Refresh Your PC without affecting your files" -> Inserted the Lenovo "Operating System Recovery Disk Windows 8 Pro (OEM Activation 3.0 Required)" BUT Windows did not accept that DVD claiming "The media inserted is not valid"... ???
6) Ended up calling Lenovo Support and they instructed me to order the Recovery DVD from [URL] ..... -> Waiting that to arrive...

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.

Is it possible to run a t500 without a battery? 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.

If I install LSDP two things happen:
1) My Start Page in Internet Explorer gets reset to some old value
2) The setting to change the default printer when I change network is switch off and a fixed printer is set as the default.
Is it possible to disable these annoying features?

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 have a Latitude E6510 that will not start. When pressing the power button, the power light goes on for about 5 seconds and then turns off. I also notice the battery light flashes a few times when re-connecting the AC adapter.
Removed the battery, held in the power button 30 seconds, but still not working.
We have had this laptop about 6 months. About a month ago, it exhibited this problem. After talking to Dell Support, they recommended a system board replacement. The laptop was sent in and the board was replaced. When I got it back and tried to start it for the first time, it did the same thing. I then pressed the Latitude "ON" button, and the laptop started.
Now it is doing the same thing, and I find it hard to believe that another system board is bad. I am suspicious about this "ON" feature, that maybe the laptop is "stuck" or something trying to get into the "ON" mode. Or maybe it is just trying to get into "ON" mode.
I am not sure what the "ON" feature does, but I have noticed a few other posts on the internet of users having the exact same problem. Again--I find it hard to believe a second system board could be bad.

My battery life was appauling (15 mins), so I decided to do a full discharge and recharge (Nothing to lose by doing it)
After this was done I loaded back into windows and checked my battery monitor, unplugged my laptop and waited 10 minutes.
It was still at 100% 10 minutes later.
I looked in another utility and it was reporting ludicrous values for Full Capacity - 920,643mWh (At this point I became very scared of the prospect of a Lithium Fire).
I worked out the capacity of my battery:
wattHour = ampHour * Volts
Ah of my battery is 2.0, and it provides 14.8 Volts
Max battery capacity: 29.6wH (29600mWh)
The program is reporting 29834mWh (Which seems like a perfectly acceptable value considering not all batts are the same)
Seems like the battery is still good... (It's certainly running longer than before, up to 30 mins so far).
I'm sure my battery is dying (3 years old), just this makes it seem like it isn't?

Apart from the fact that I had too many problems with my L502X laptop, right now my problem is:
When I press power button on the device, battery icon blinks white twice, then system boots up. But normally there should be light on Power button and other 3 shortcut buttons, but they keep dark even though laptop works.
There is no error message or something else related with my battery, and windows says that battery is fully charged when it's plugged in which is pretty normal. I tried diagnostics but there wasn't any error messages.

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?

My Inspiron 1520 just recently started blinking a red battery light. It just keeps blinking. Theres no stop to it... even if i re-insert the battery it shows the blinking red light and it keeps blinking steadily. Also when checking with quickset it doesnt recognize any battery at all. When i remove the ac adapter my pc just shuts off and wont run until plugged in. I read in the manual and it told me to contact dell if it happened.
I dont know if its defected or something? My warranty is pretty much dead... and I've always left the computer plugged on.. dont know if that affects the battery. Will I have to replace my battery, if it runs out or is defected? I checked and its $135 bucks for a new battery....

I just got a brand new Thinkpad T540p. I'm very happy with it, but I miss the battery indicator I had in the taskbar on my older Thinkpads:
I am trying to get it back/install it, but I keep failing at it. In particular, I have searched around ThinkVantage Power Manager software, found and installed this: [URL]

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.
