ThinkPad X230t Does not run on battery

Q: ThinkPad X230t Does not run on battery

My ThinkPad X230tSuddenly stopped working on battery and works only on charger plugged in. I thought the problem was with the batter so I brought a replacement. I replaced the battery with the new one, but it didn't work, so I thought the battery was empty. I connected the charger and charged the batter full for an hour or so till it was 100% charged, yet, when I unplugged the charger the laptop was dead. What could be the problem?

Hello! I'm experiencing a problem with the BIOS/UEFI version 2.72 for the x230t model. The file isn't working correctly. When I try to install it there's only a message that "The BIOS directory cannot be found". I also tried the ISO image and it does not contain any data.Is there anybody with the same problem? Thanks for the response!

Hello
I have recently purchased a lenovo thinkpad x230 tablet from ebay. The seller specified that the laptop supports both touch and pen input. But only the pen works, the touch screen doesn't work.
After searching online quit a bit, I discovered that some models of x230t are only pen input (no touch).
But I don't know if that is the case with my laptop or is it some hardware or software problem, and I wasn't able to find any online documentation about the models that support touch.
My model number is: 3438-2S1, and my serial number is: XX-XXXXX.
Also attached is a photo of my laptop screen, if it helps in anyway.
Can anyone please help me?

Hello Friends,
 
I recently purchased a Lenovo X230 tablet PC (3435-24U) and I love it.
After MUCH debate with Lenovo, however, I think I have determined this: While the unit has a symbol for a light (either backlight on keyboard or thinklight on screen) on the spacebar, this particular model does not have that feature.
 
1. It's a shame because it's a great feature, and I hope my diagnosis is wrong, but when I press the function key and space bar together, I get no light, and get a symbol on the screen of a light with a circle/slash through it. Seems like no light to me, yes?
 
2. As a fallback, I see that X230 BACKLIT replacement keyboards are available for under $50 on the internet and wondered if any of you had any luck switching out a non-lit keyboard for a lit one, either by yourself or with professional help.
 
Any insight on either issue would be greatly appreciated.
Thank you...

I am in the same boat. Recently bought an X230T and thought I was getting a backlit keyboard only to find it is not.I found a vendor on Amazon that has the keyboard, and am considering the $35 gamble on buying it and trying it.I've tried decoding the FRU numbers that Lenovo uses to verify I am getting the keyboard I need/want, but those things have about the worst description ever.Otherwise I'm loving the machine.

Hi, My issue is that my Thinkpad x230t screen is somethimes just freez. More accuratly maybe will be to say as it seems like someone put a gray or sometimes black box on the screen. Sometimes you can see few lines on pixel from the screen and if i press the winkey over and over i can see something happen, and sometimes everything is just grey or black.  Basiclly i have a docking station so i can say the following:1a) when this happens and i connect it to external monitor - everything works fine. So i guess its not the GPU.1b) Also i guess it is not a program issue.2) Lenovo test program doesnt detect any issue.3)The issue seems to randomaly appear. Also the time the screen freezing is randomanly. It can be 5 sec or 5 min.  Anyone had something similar?I thought maybe this is the cable, but than i would expect that if i move the screen i will see a response.Thanks.

The the replacement unit has the same problem. Thinkpad Thunderbolt 3 docking station does not charge Thinkpad P51 battery.  I need to plug in the power adapter for both docking station and notebook.  Does anybody have similiar problem? 

A:Thinkpad Thunderbolt 3 docking station does not charge Thinkpad P51 battery.

Everbody's p51 would be the same.  The thunderbolt port won't work as a charging port.  The thunderbolt specs specify 100w max.  That's not enough.  Your thunderbolt port is not for charging.  To charge via the dock, you need a workstation dock, not a thunderbolt dock.  A thinderbolt dock can charge things like an x1 carbon (5th gen) or x1 yoga (2nd gen)

I have a ThinkPad T450 with a built-in and external batteries.  Is there a setting in the BIOS or in the Lenovo suite of software where one could set how the batteries behave when they're being used? I'd like for the external battery to drain first so that I could then switch it for a different one before using the internal one.  It's always easier to replace the external battery vs. having to remove the bottom case entirely to access the internal one.

Hello!  I am seeking the sage wisdom of veteran thinkpad owners for an upcoming purchase.  I am considering an x250 (i5, 256 ssd, 8gb, 1080P ips non touch, with nothing but a fresh install of Windows 10 pro 64 bit and MS office pro plus) to use for the next two years while I complete a degree(mostly paper writing, web browsing, netflix/youtube etc..nothing heavy). I prioritize a good keyboard, good battery life, light weight(under 3lbs), durability, and saving money if possible.  With that said, I can't deal with laggy performance and lackluster battery life. I "could" buy a new laptop, but am having a hard time justifying spending that much since my usage is so light.  My previous laptop was a macbook air and it served me well, but the keyboard never really impressed me. I sold it, bought a nice Chromebook(12.5 inch screen) and pocketed the change. I have not had a "real" computer for a few years now and it's time.  What say you? 1) Will the above spec x250 provide me with decent performance/battery life for the next two years?1a) What kind of battery life can I expect with this setup and a flush battery?  2) Any other recomendations? I really like the X1 carbon, but the price is tough to swallow with all the issues I am seeing. However, that larger screen sure would be nice on the eyes. 3) Though I would prefer to not get another macbook, with the rumored update to the macbook air right around the corner said to be arou...

Battery 2 is not being used but it is not charging either and it is very very slowly discharging (about 3% over the last few days). If I plug the Thinkpad into its normal power supply outside of the dock both batteries charge (one at a time). Is this normal behavior or is there something wrong with my dock?

Hi to everyone, let me introduce my problem:  I live in Chile and I wanted to renew my 2010 Lenovo G60, so I bought from Amazon an 11e (not available here in Chile) and the only problem I am having is that the battery drops dramatically while it is being used (I take care of the battery with everything I can via Software and by using the PC with care), even though I have updated everything, the problem keeps going on. The Lenovo battery "doctor" says it is working fine and when I download the battery software updater, it shows that my battery needs no update. Has anyone have had this problem too? Thanks  PD: I forgot to mention that it is the one with Windows 10 and 128GB SSD (20D90020US)

I bought a second-hand IBM ThinkPad T30 at the start of January. I bought a new battery for it a while ago, and I've had to get two replacement batteries because of problems. The guy who sold me the computer told me that you shouldn't keep charging the battery after it is already charged - what he means is that when the battery is fully charged you should take the power cord out and run it on the battery. Has anyone heard this before?

Should it be okay to keep running the computer on the mains after the battery is fully charged? Would it be all right to remove the battery?

I am looking to replace the internal battery for a Thinkpad X1 laptop.  the Model number is 1294AY2.    This is an older model with the internal battery.   The current battery appears to be a 4 cell, and I can find replacements online.  I thought I read an early review that mention an extended life 6 cell for the internal battery.  Is this an availbale part number? The installation process for the internal battery seems a little more involved.  Is there a recommendation on how to best do this without any permanent damage.  Is there an official repair manual that is available to the pulic? Since this unit is out of warranty, I assume that it is not a option available by sending the unit to Lenovo for service. I am curently getting about 3.5 hours battery life now, and the system reports 30,740mWh, compared to 38,920 rated capacity.  Can I assume that the battery has degraded by roughly 25% by comparing the 2 number, or is it a more involved calculation? Ideally I get 5-6 hours of life, and I am considering adding a "battery slice" instead of changing the internal battery. BATTERY 1NAME42T4977MANUFACTURERSMPSERIAL NUMBER472CHEMISTRYLiPDESIGN CAPACITY38,920 mWhFULL CHARGE CAPACITY30,740 mWhCYCLE COUNT-

A:Battery NOT Re-Charging for ThinkPad P71

Win7 or Win10?  Probably the latter.
 
Is the latest Power Management Driver (for 7/10) installed?  Power Manager (for 7) installed?
 
Barring a defective battery or some other hardware issue with your P71 (and worst case, it's under warranty so you can call Lenovo to open a ticket and get a technician to come out and solve your problem with appropriate parts replacements, whatever it might be), it might be that the software is simply deciding not to "charge" because of a battery plan agenda or Registry values set so that no charging is occurring (under software control) even though you've now tried to drain it a bit so that it really should have reached its lower-threshold to reactivate charging.
 
I recently learned of a Registry hack to set the low/high limits in Win10 to match the customizable values for the Lenovo Win7 Power Manager (which does not exist in Win10).  After installing this REG file Win10 battery charging behavior will work like it does in Win7 with Power Manager, meaning there is your own low threshold value above which no charging occurs but below which charging once again kicks in.  And then charging continues until the upper threshold is reached at which charging stops (thus avoiding charging all the way up to 100%, but stopping below it... say at 96%).  Curiously, Win10 seems to reset the primary parameter values of the REG file whenever a Windows Update is applied (e.g. overnight) or on other unknown circumstanc...

I bought a Thinlpad R51 - 1836 BBU used and with no battery. I bought a new battery, installed it and the battery drained completely. I sent it back and got a new one and also bought a new power chord. The battery and new power chord worked fine for two months. Last week the battery drained completely again (while plugged into AC chord).

Again I bought a new battery (extended life this time) and bought a docking station. I am now faced with the new battery drains everytime I use it. The power chord does not charge it. The docking station does not charge it either. I would like some questons answered:

Is it normal for the pc to have to be ON for the battery to be charged?

Does anyone know if there is any indication that the power chord is plugged in while the battery is installed? When on AC only, it shows plug - When battery installed (on battery only or with AC chord) computer shows on battery power.

Do the external battery charger units really work? this may be my only way of recharging my battery if not through the pc.

Any help would be greatly appreciated.

Assuming both are genuine Lenovo. All dimensions except height (which noone bothered to measure) - are the same; even if the 370 battery is slightly higher and won't fit without lower case modification - it's nothing a rotary tool can't fix. 370 battery: 15.28V 51Wh (FRU 01AV433)260 battery: 15.2V 44Wh (FRU 00HW027) Is there any particular reason why it definitely won't work? I'm really on the verge of ordering one and trying for myself, but I'm not sure how does embedded controller (EC) determine if the battery plugged is correct,  and not really want to waste time if the idea is doomed to failure because some technical quirk I am not aware of - hence the question.  Why: while 370 is newer, it has glossy PWM display which ain't bonded with digitizer vs bonded matte PWM-free on 260. 260's weakest spot, on the other hand, is poor battery life - larger 370 battery could definitely resolve this problem. I'm bored until newer Thinkpads are introduced at CES 2018 anyway - so why not give it a try, if there is any chance it may work.

Hi everyone, Just wanted to report a problem I've been having with my Thinkpad Yoga 460 (core i5 6200U, 8 GB RAM - 20EMCTO1WW). After only 3 days of light use and a BIOS update to v1.40, I found that the laptop would only start when connected to the charger. In Windows 10, the battery gauge would show "99%, not charging" permanently. Importantly, the system does not seem to recognize that the charger is connected and thinks it is on battery. If I pull the charger, the laptop dies instantly. Also when I plug it back in, the charge indicator light flashes orange a couple of times for ca. half a second and then stays off, even when the laptop is on. First I suspected a software fault, and tried a lot of different permutations of uninstalling, re-installing and disabling the battery driver in the system manager, as well as the different Lenovo-branded system programs. The Lenovo Solutions app does always seem to display the same information about the battery, importantly with the charge cycle counter unchanged. None of it seemed to help. Growing desperate, I tried a different power supply (no difference). I also unscrewed the back plate and unhooked the battery cable. While then the system did not recognize the battery anymore, everything was back to the old, unrecognized state after it was hooked back in. I tried resetting the battery as recommended in this thread, but to no avail. I tried to downgrade to the BIOS version 1.18 (the one the laptop had bee... Read more

Hi,
Sorry if someone had answered this question before but I'm new here.
I have an IBM ThinkPad T22 and recently experienced this strange problem: The battery works alright but it doesn't charge even though the LED blinking as if it is being charged and when the system was poweroff and I unplugged the AC adapter then the LED indicating battery was still lit although it was supposed to turn off. To really turn that LED off I had to remove the battery pack. I discharged the battery completely and it's not charged any more
(0% charged) and now I have to use my laptop as if it is a desktop (with power plugged all the time). I would be grateful if you have any suggestion since I believe that the battery is still working pretty well.

The battery light is blinking orange. It works on ac power. The power manager says that the battery needs to be charged for 10 hours or more because it was fully discharged. It also says the battery is brand new. I tried charging it for 48 hours and it still didn't work. I don't want to buy a new battery if possible. I got the computer used so I don't know how much the battery was used.
