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

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).

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

Hello,
 
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?

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!

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,

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.

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.

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.

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.

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,

plsrepli

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?
James
 

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.

A:Y40-80 Battery 0% Only works with charger

Try removing the battery and reinstalling it. it may not be connecting properly or snapped in all the way. Some components have an FRU # on them which is the field replaceable part number. I don't see why the battery cannot be shipped to you anyway. But you need to call Tech Support to process this since the forum is NOT tech support only a forum of users primarily.

My hp envy x360 notebook is not responding accurate battery time i.e shows 10 or 20 mins remaining on 80% charged but after 10 mins it gives warning battery is too low and then trip the notebook. but amazingly sometimes it works perfectly and gives 3 hours battery backup time easily. Using this notebook about one year. can any one give me some clue. faraz

A:Battery works accurately but sometimes not.

Is the notebook still in warranty?Check your warranty status Here. The warranty covers main battery replacement without cost to you. The only thing you have to supply is the box to safely ship it to the HP service center. HP will arrange for the shipping of your notebook. This does work, I had to use it for my 15 year old daughter's notebook last year and she had it back in her hands within two weeks. Copy all important information to an external storage device before you send it.  Once that is done, you can remove any personal information form your notebook.
