T450s only works on AC when battery is removed

Q: T450s only works on AC when battery is removed

Hi all, My 2-year old Lenovo T450s is experiencing charging problems. If I plug in the battery charger, it starts charging for a second, it then stops, then the cycle starts again. Needless to say that none of the batteries (neither the built-in nor the external) charge properly. I tried to: (1) buy a new battery charger, (2) unplug the external battery leaving the internal plugged in, (3) unplug the built-in (internal) battery leaving the external plugged in. None of these solutions worked. I then unplugged both batteries and plugged the battery charger, and the laptop works. What do you think? Is it a hardware problem (perhaps related to the motherboard - I can't think of anything else)? Is it a software problem? Thank you in advance for your time! Best, Paolo

Preferred Solution: T450s only works on AC when battery is removed

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

A: T450s only works on AC when battery is removed

I cannot be sure without seeing it, but I would guess motherboard charging circuitry. I am assuming it will not charge while turned off.

Are you still under warranty? Many are 3 years

Hello. My name is Aaron Hervey. I have a Hp Spectre x360 15 inch. The problem is that my battery is detected as missing. I can plug the AC adapter and turn it on and everything works normally. However, if I unplug it, it does not shut off immediately. In fact, it works just fine without the ac adapter. I only need it when I need to turn the laptop on, but other than that, it's fine. I did update he BIOS and performed a primary battery check using HP support assistant, but nothing works. It still identifies as undetected. I haven't performed a hard reset because I am hopeful there is some other option besides that. I use the standard adapter and everything. I have not dropped it. I have not replaced the battery or removed it in any form or fashion. It functions fine and has not been damaged. Please help me with any suggestions u might have. Also, I did boot up the startup menu and tried to check the battery there but no luck. I was also informed that I should unistall the battery drivers, but was hesitant and didn't know if that was a safe option. If you have any knowledge of my problem, please reply to this forum. Thank you. Also, it is under warranty and I did call hp. The recommended I ship it back

Hello everyone! I use the t450s for school, and I'm very happy with it thus far. My only complaint is battery. Just today, I realized it had a 2nd battery. I'm relatively unfamiliar with it, so could someone please tell me how it works? Does it kick in after the 1st battery dies? Do I have to enable something? Thanks guys!

Hi, I have a user at my company the let's her T450's battery rundown to empy... (She leaves it in sleep mode over the weekend and the battery dies) This happend a while back and I had to leave the laptop on charge all day, unplug the battery, hit the reset button on the back and then plug everything back in for it to start up again.   Today, this issue happend again where the user ran the battery down to 0% and now the laptop will not boot up at all.  I tried the following things noted below but all the laptop does is display three quick power button flashes when I plug the power cable into it.   *Uplug the power cable and the battery.  Hit the reset button on the back and then tried to power it on - Nothing*Uplug the power cable and the battery.  Hold the power button down for 30 seconds and then tried to pwer it on - Nothing Going to leave it sit for a while but I do not think this is normal when someone runs the batter down to 0%.   Has this happened to anyone else or is this laptop dead and I will need to send it in for service?  Would like some thoughts on this...  Thanks!

Hi everyone, Just received my T450s. Installed the rear battery, then plugged in the power.  On my old T510 I have an indicator showing me when I have power hooked up, and indicates the charging status of my battery.  I don't see anywhere on the T450s chassis that indicates the status of the battery charge. The only thing I will see is the dot on the "i" on the top cover, flash when I connect power.  Surpised there isn't a status indicator. Peter

A:Just got my T450s - no battery charging indicator?

No, there is no charging indicator on the T450s. By popular demand, Lenovo added one back to the T460s.

My T450s has recently started discharging the internal battery first rather than the removable battery. I can't recall when this started to happen but I think it happened when I updated the BIOS to the latest version currently available. Anyone have any insight if this is an issue with other models and a fix? This is rather annoying. I have updated all of the other drivers with the System Update utility from Lenovo. Machine Type: 20BW

Hi, I like that my T450s has 2 batteries. But the thing that bothers me is that the removable battery is drained first entirely prior to using the built-in battery. I've noticed that this increases the "cycle count" of the removable battery as essentially the battery has been completely used. In other laptops this is not a problem as they come with 1 battery and the cells are depleted uniformly.  This has only become a concern for me when I want to use the laptop for long hours without a charger. This would increase the cycle count of the removable battery if done on a daily basis. By doing so will I be ruining the battery life ?  Pls let me know, thanks.

A:T450s - How many cycles can the removable battery ...

Not sure, but I guess this is a bit by design, True the external is wearing more by having more cycles, but this also means that the internal one has a increased live time. The external one will be the first to wear, but is also the more easy one to replace .I already have 2 externals with my laptop.But I get your point and I'm curious about it too. Depleting a battery fully will wear a Li-ion more then not fully depleting it (if my study's where right that is). So it might be true that the less wear on the internal battery does not compare equally to the extra wear caused to the external battery.On the other hand, the extra wear might not be that great to worry about. And this dubble battery design does give us the awesome feature to hot-swap external battery's (which I use quite more that I thought I would).

I got a T450s, brand new and everytime I am not plugged in (it's a laptop after all) the computer litteraly slows down to a point where it is unusable, a simple key (space, a letter, a number) will usually take 3-5 second and sometimes up to 20 seconds to register, no software is usable, CAD, video playback and authoring, completely useless when on battery. The thing is this is a laptop, I WILL use it on battery. That is despite me choosing high performance in the Lenovo power manager.
Anyway I can fix this?

I have read quite a few threads regarding Lenovo laptops requiring the battery to be disconnect to get the unit to turn on once it goes to sleep or is manually shut off.  I started having this issue on my 3 year old t450s about 3 months ago.  I disconnected the internal battery so that starting it up only involves removing the external battery. Is there a solution to this issue?  Of course I'd like to resolve it on this laptop but I'm even more concerned about purchasing an new t model laptop.  Love the laptop but am frustrated by this issue. Mark

After a long journey, both batteries in my T450s were flat, and this morning when I plugged in and booted up I got the message that "The battery installed is not supported by this system and will not charge".  True to its word, one of the batteries does not seem to be charging.  These are the original batteries which came with the laptop when bought new from Lenovo.  They have performed well since I received it, no problems to date, and no obvious reduction in performance.  How can I get the battery charging again? Thanks for your help.

My battery all of a sudden won't charge. The computer works with remaining battery (when AC is not plugged in). The computer works with the battery removed when plugged in. But if battery is in and the computer is plugged into the outlet, it does not charge the battery, nor does it recognize that it is plugged in. It only tries to run on the remaining battery. WHen the battery is in and the computer is using the AC adapter, I get a blinking white light next to the plug for the AC adapter. I have two separate batteries, and it is doing the same thing on both batteries. I have tried deleting the  Microsoft ACPI-Compliant Control Method Battery and the Microsoft AC Adapter in the Device Manager section. It didn't fix my problem. I also used HP Support Assistant's HP Battery Check diagnostic tool. It says my "battery is functioning correctly, but the AC adapter is not attached. To completely test your battery, please attache the AC Adapter." The strange thing is, my AC adapter is plugged in, but the computer thinks it is not attached. So it is not recognizing my AC adapter when the battery is in. But does recognize and use the AC adapter when the battery is removed.  Does anyone have any recommendations for a fix? Thank you!

My battery was dying. I tried calibration, letting the lenovo run just on the battery. It looks like it went down to 0%, then shut off. But it wouldn't charge. It was probably never charging in the first place, always running off the power of the AC.  But I could still boot to AC. So I bought a new battery. It said to calibrate. So I tried that. The battery ran down to maybe 20%, then shut off. But the same result. Laptop will neither boot nor charge the batttery. Again, it will boot just fine with the battery out.  So, what's to be done? Also, I tried to get into the BIOS via F2 and F12, but that doesn't work either.  - Dan

It had a ton of malware / viruses.  LaFlurla, among others.
Scanned and cleaned with Comodo CCE, and MBAM.  
After three or four passes all came up clean.
But now...  nothing works.  IE opens, to MSN.com or whatever the first page is, but then won't go to any other pages.  It just spins with two iexplore.exe processes in taskmgr.  One taking up 50k+ RAM, the other 4k~6k.  Closing either closes both.  
Can't do windows updates - it downloads, installs, and reboots, then notes "failure" and reverts.  I can do one or two at a time fine, but the system needs some 120+ updates as it had not been updated in a long time.
Won't install SCEP.  0x80004002 error when it gets to the update part.
All sorts of WMI and DCOM errors in event logs.  I got the DCOM errors sorted, mostly, and followed various support articles on the WMI errors. 
But I have hit a wall
Attaching full logs of MBAM, and Farbar Recovery Scan.
Any help appreciated.

A:Malware removed (I think...) but now nothing works.

Well, those MBAM logs are pointless - I swear each time it was finding tons of stuff, and I exported the log and then cleaned.  Great.  That will help this process so much.

I removed E-Trust, MyWebSearch, PartyPoker, Tramadol, TimeClock, and NetworkMagic from my PC, and can no longer connect to the internet. I'm on broadband with an external SURFboard, running through a D-link DIR-625 wireless router. I'm running windows XP on both the PC and this Dell laptop. The laptop connects(sometimes it takes a couple tries), the PC will send and receive emails, but every time I try to connect, I get the IE cannot display webpage screen. I've tried every Wizard, repair, diagnostic program in Windows, and NADA. You are my last hope before I try dumping everything and starting over. Since I can't connect, I downloaded Hijackthis onto a flash drive from this comp, and ran it on the PC. If someone thinks they can help, I can copy the log on the flash drive, and post it here. Right? Thanks in advance,

A:I Removed The Problems, Now Nothing Works

Well, it didn't work. I downloaded Hijackthis, Hijackthis reader, and DSS.exe. Hijackthis opens the scan page, but whenever I try to click on something, is says it's being used by something else, and clicking switch to or retry does nothing. DSS.exe starts creating a restore point, and after an hour, is still sitting on the first block of the progress bar. The reader seems to work, but I can't use it without the first program. Can I not use a flashdrive to transfer it to the affected PC? The PC has been trying to shutdown for about 10 minutes now, it's not looking good.

But still something blocks standard http and https ports. At this time I am resorting to a wipe reinstall on this clients system because it's an Asus EEE PC and has no repair install options.

After it finished a full scan, and I clicked remove all etc., it came up with an error just before reboot saying that "certain items could not be removed. a log file has been saved." It then came up with a Runtime Error! for mbam.exe in Program Files, saying the 'appliction has requested Runtime to terminate in an unusual way. Contact support.....etc' Since rebooting XP Security Center 'appears' to have gone, for the moment, but everything else is pretty much screwed:I can't access any secure sites in Internet Explorer, and can't access anything in Google Chrome;I can't access Windows Firewall Settings to check on this;The only thing I installed recently was skype, but this now keeps opening window after window of the same help page (it has the feeling of XP Security Center to it) for no reason;Trying to even access 'Add/Remove Programs' - comes up with 'C:\WINDOWS\system32\rundll32.exe - Application Not Found' - despite the fact that rundll32.exe does exist in that folder;I can't actually open any program at all, without the 'open with' box coming up.

You are likely OK. If you had seriously damaged it, it would probably fail the memory portion of the POST (Power On Self Test). It is not the best practice to do what you did, but you did have it powered off, so you should be fine.

I would read your manual, especially the setup part, you may have hosed your bios settings and need to go into bios and let it redetect everything.

Some times after adding memory or making changes to the computer configuration, just going into bios fixes the problems.

You have to exit and save changes

I am spending my summer at my village. Temperature here is constantly 40`c to 45`c, which is very hot as compared to the capital where i live. When ever i put laptop battery the laptop heats up, and battery timing also is reduced from 3 hour to 1 hour. So i have removed the battery and using it on A.C.

Here is my query and experts are requested to give their valuable suggestions.

Firstly, is it a wise idea to use laptop without battery on A.C, if not what should i do?

Secondly, will keeping battery removed and idle effect its health because i am going to spend one whole month here.

Thirdly, if it is a wise decision to remove it, where should i store it? The temperature is so high and there is no air conditioning. The only cool place is fridge. But the humidity could affect the battery in such place. Kindly suggest a place to store battery.
Looking for a speedy reply from Tech Guy as usual.

OK, please bear with me: I'm not a newbie and not ignorant of basic Windows parameters but neither do I consider myself an expert - hence seeking your generous help!

I am running as TESTADMIN, an account which is a member of the Administrators group on a Windows 10 x64 Nov update machine. This was a clean install, not an upgrade.

I have installed an application (Quickbooks Premier 2016) as TESTADMIN. Everything generally works fine but there is one component (which I have to use) which needs UAC permission to activate. That component starts a service that allows sharing of files across the network. Once that service is started, the application seeks UAC permissions to open. Despite them being granted, the application fails to load. The service however, loads fine and indeed does successfully allow the files to be shared across the network with other installations.

If I activate the hidden ADMINISTRATOR account and run the program from within that account then I have no problem whatsoever. I have tried downgrading the UAC rights of the TESTADMIN account but no luck.

The service, the files accessed and the program files all have permissions that give read/write access to TESTADMIN. I can see nothing that TESTADMIN does not have permission to access.

My understanding was that the ADMINISTRATOR account differed from TESTADMIN only by it's degree of UAC control. But clearly there is something else the ADMINISTRATOR can do that TESTADMIN cannot. How can I found out wh... Read more

EDIT: The only way I can think to fix your issue without a complete reformat is to do a registry backup from a known good computer, and restore it via reg.exe (command line). That might restore the registry enough so that you can roll your system back to a known good restore point.

Hi @ClevelandFamily, Thank you for visiting the HP Forums! I have looked into your issue about your HP 15-f211wm Notebook and it having startup issues.  I would try reseating the Battery. Maybe it did not sit in the Notebook correctly. Try performing a Hard ResetWhen performing a hard reset please note remove any and all USB devices. Disconnect all non-essential devices. Plug the power adapter directly into a different wall outlet. Do not plug it into a power strip, surge protector, or secondary power source as this could cause and issue. Please let me know how this goes. To simply say thanks, click the Thumbs up below!    If you require further assistance let me know and I will gladly do all I can to help. Thanks.

Hi there, I'm having issue with ThinkPad X220 laptop.. This is the issue With battery = Running perfectly & smoothly With battery and charging wire plugged in = Running perfectly & smoothly !- Without battery ONLY charging wire plugged in = Runs very slow. CPU looks limited to certain percentage, won't run higher than 25%. -! Tried changing around battery power option no different.. also tried see-ing at the Intel Graphics Application.. like no changes. I think is something related to CPU being limited... but I don't know how to change.. can someone help me.

Hello all,

My hard drive activity LED was blinking on a routine basis so I used Process Monitor to isolate the problem to a PID 4 process which appeared to be flushing the hard drive cache on a routine (and continual) basis. So, I went through the process of trying all different HD write cache combinations (disable, turn off) but the flushing continued. The final fix was to put the battery back in the laptop and this stopped the routine access and the HD flushing ceased. Now, I'm only guessing but this routine flushing appears to be a defensive measure, initiated by some process related to the the power scheme, to prevent data loss when the battery backup is not available. However, since I only use this laptop on a very infrequent basis, and when I do, I would like to use it exclusively on AC, I would like to keep the battery removed on a permanent basis. Note: The continual HD access does have a slight impact on performance. I wish there was some way to install Win 7 on a laptop and give it the power scheme of a desktop. Any suggestions?

Thanks, in advance, for your responses,


A:HD Activity LED Blinking Every Second With Laptop Battery Removed

You can do that by going to Control Panel\All Control Panel Items\Power Options\Edit Plan Settings and click on Change advanced plan settings and set everything to max performance or disable power saving features.

My HDD light blinks at 1 seconds intervals too and is caused by the system polling the CD/DVD drives for a disk.

Windows Security Essentials has detected this trojan "Hiloti.gen!D" on three occasions, 4/17/11, 5/1/11, 5/9/11. I never began having the internet problem until the second occasion. When I remove it the internet works for a short time and then may go VERY slow or stop working. Haven't had the trojan show up again on full system scans in safe mode and normal mode, so I don't know if it's what the trojan left over that is causing this or what. All the other computers in the house have internet that works fine. It will say it's connected and that there are no problems but it still won't work. I also get occasional site redirecting. I was getting a lot more until I used Spybot S&D and it removed some spyware. I know I need to be more careful on the internet now. Followed the instructions on what to do on the preparation guide, so yes I ran the Defogger beforehand.

I have a HP Probook 4730s and it has an i7 processor, 8gb ram, 700GB HDD. I have this new software program called Corel Videostudio Pro. I am in the middle of rendering a large 20GB HD video and all of a sudden the computer shuts off. And the weird thing is that I cannot turn it back on, even when plugged in. I can only turn it back on when I remove the battery and replace it.
What can I do to finish this rendering of my video without the computer shutting down?

A:Computer turns off, can only turn on when battery removed and put back in?

Install this software CPUID Hardware Monitor and check your system temps when you are rendering the video, I suspect an overheating issue.
