My early 2011 MacBook Pro says battery not detected and does not work with a new battery either. Works only with the charger plugged in.

About a year back i had replaced the MLB of my early 2011 macbook pro and it was all working fine. A month back my battery went dead saying "Battery Not Detected". I went to Ample technologies, Bangalore, India and gave it for diagnosis. Ample technologies are the authorized Apple support service in Bangalore, India. After 3 days and no phone calls they email me that "They feel that the MLB MIGHT be the problem and they want to test it by replacing the MLB and i have to pay for their testing". I had already spent 40k indian rupees ($700) less than a year back to replace an MLB and now they want to replace it again at the cost of 43k ($750) indian rupees. I have no idea what to do now. Spending 80k indian rupees ($1400) in less than a year to replace the MLB twice sounds unfair to me. Can someone help me out here ? Is there a valid warranty period applicable , since i have changed the MLB a year back ?

short of doing a SMC reset, you maybe at their mercy.

Lenovo G710 Battery not detected in Windows 8.1 64 bit

Hi there,
I have the Lenovo G710. I haven't used the battery for a while now and I use the laptop by connecting the powerlead directly to mains power outlet. I decided today to plug the battery in. The battery indicator lights up.
Windows 8.1 does not detect the battery and it states "No Battery Detected".
What i have tried:
I have installed all the latest Windows Updates and it still doesnt detect the battery.
I even installed the latest chipset drivers for this laptop and it still doesnt detect it. The only update i cannot install is the BIOS update because it states that "Battery Not Detected".
I uninstalled the following from Device Manager: Microsoft ACPI compliant Control Method Battery. Switched off the laptopRemoved the battery packRemoved the AC power lead from the laptopHeld the power button for 30 seconds to drain the batteryReconnect the battery packReconnect the AC power leadTurn the laptop on.Battery not detected.
Can anyone assist what i could do next please?

Presario CQ 71 - Built in Webcam not detected under Windows 7 Professional - No HP-101 device

I have a Compaq Presario CQ 71 EB400. On this notebook I run both Windows 7 Home Premium 64-bits and Windows 7 Professional 64-bits to compare behaviour of apps and windows features in both environments.
Windows 7 Home on my HD C partition
Windows 7 Professional on my HD F partition.
The CQ 71 has a built in Webcam, that shows up under Windows 7 Home premium Device Manager - Imaging Devices (Cameras and Scanners) as HP-101, linked to the required drivers.
Under Windows 7 Home premium:
- The built-in CQ 71 Webcam is detected and operational - the HP-101 entry is present in Device Manager.
- Applications using a Webcam like Skype, Mycam, Manycom etc connect with the Webcam
- When I plug in an external Webcam, thet webcam is detected as well, drivers loaded etc.
Under Windows 7 Professional:
- The built in Webcam is not detected, in the Device Manager -Imaging Devices, the HP-101 Webcam entry is absent
- Skype, Mycam, Manycam cannot find a Webcam (also not when an external USB Webcam is plugged in)
- A plugged in external Web cam is not detected as an imaging device.
I use a Brother printer/scanner/fax machine, the Brother scanner device is visible as Imaging device in Device manager in both Windows 7 Home premium and Windows 7 Professional.
Other USB devices, portable disks, card readers etc seem to work OK in both Windows 7 environments.
The HP support pages provide information what to do when a internal Webcam is not detected; The recommended actions make no difference. Going back to a previous W7 Prof restore point is no option, as on the CQ 71 notebook the built-in Webcam never functioned under W7 Professional.
The major difference is that all Windows 7 Home Premium relatede system software resides on the C partition, all Windows 7 Professional system software on the F partition.
I'm looking for a way to kickstart the built in CQ 71 Webcam under Windows 7 Professional installed on a non-standard partition.
Your suggestions will be very welcome.
Jan Dijckmeester.

Hi again jdij,
It is good to hear back from you!
To enable your system to detect the Webcam in Windows 7, I recommend re-installing the original drivers and software that first came with your computer. This can be done by following the steps in this document on Using Recovery Manager to Restore Software and Drivers (Windows 7). To update the newly installed software, please follow this resource on Using HP Support Assistant (Windows 7).
If the webcam is still not detected, I recommend returning your system back to a previous restore point. This can be done by following the steps in this document on Using Microsoft System Restore (Windows 7).
Should the problem continue, I suggest performing a backup and recovery of your operating system. This can be done by following the steps in this resource on Backing Up Your Files (Windows 7), as well as Performing an HP system recovery (Windows 7). This should return your system back to factory defaults.
If the issue persists, please call our technical support at 800-474-6836. If you live outside the US/Canada Region, please click the link below to get the support number for your region.

Thinkpad Edge S430 - Windows does not detect external display connected via HDMI

On a Thinkpad S430 with HD4000 integrated graphics, an external display connected via a HDMI cable is not detected at all when using Windows. The system is fully updated as of the time of posting this message, both via the Lenovo Update tool as well as Windows update.
The Intel driver version is 8.15.10.2696. It appears that this is the latest version, since it does not offer an update when I try to auto-update it via Device Manager.
NB: I am running Ubuntu 12.04 with kernel 3.4.0 on the same machine, and the external display works perfectly fine with this software configuration.
Hence I think that it's very likely that this is a Windows-specific driver issue.
Would Lenovo happen to have a driver update in the works? Alternatively, I will be thankful for any suggestions about possible resolution of this problem.

Qosmio G10-133 - Battery not detected following Windows 7 upgrade

Hello, I hope someone can help my frustrations here.
Over the last couple of weeks I have successfully upgraded my laptop to Windows 7, increased memory to 2gb, purchased new laptop power lead, brand new battery and and resolved every issue that Windows 7 threw at me. The laptop and works like a dream other than one issue that seems to have got worst.
The laptop no longer recognises the new battery.(picture of battery with cross through it and a power plug) For approximately a week after installing the battery it worked okay but now will not detect it all. I have no errors in the device manager and windows has recognised the ACPI battery entries etc and has no issues. I have also loaded the Toshiba value added package that Windows 7 found for me but still nothing. The battery does not even charge although sometimes the battery works for around 30 secs on boot up if the battery is removed and put back in, and then stops again (once Windows has loaded) I have tried numerous things like disabling driver, reinstalling battery etc but nothing. I did try the battery iniitally with Windows XP and worked fine.
I have also searched the web and have seen many other laptops with Windows 7 have had this problem, including Toshibas. Some say update the BIOS but Toshiba have not released an upgrade since the original one in 2004 (which is for WIn XP Media Center) and there are no settings in my BIOS for ACPI etc.
Also, I cannot calibrate the battery as I cannot do anything with it. I dont think this is an issue though.
If anyone has any ideas I would really appreciate it or any links to any drivers etc.
If this is sorted my laptop should last for another 5 years!
Thanks for reading this.
Dickie

Hi
First of all I doubt that many other notebooks with Windows 7 have this issue. I never heard about this and normally the battery charging will not be controlled from the OS. It happens automatically and your battery will be charged if the AC/DC is plugged in. So the OS doesnt affect this!
To be honest I also dont know why your battery isnt detected but what happens if you power off the notebook and leave the AC/DC adaptor connected for 24 hours? After this it should be possible to work on battery minute for 1 hour or more.
If not it seems to be a hardware issue Maybe the battery doesnt work properly anymore and should be replaced. You should contact the dealer where you purchased it
By the way: Here are some nice and interesting tips about battery:

Built in iSight Not Detected

Hi,
Having an issue with my MacBook Pro where in iMovie, I am not able to select my built in iSight as an input source to record with (Camera Not Detected). Photo Booth works fine, and the issue recurs in a clean account.
I have no problem with this software on both my MacBook (2008) and iMac (2006), running the same OS version. I'm assuming this has something to do with the new hardware.
Apple Support claims that the software is incompatible with Snow Leopard, but is working fine otherwise. Just wondering if anyone here has had the same problem and has been able to shed some light as to why this occurs/ how to fix it.
Thanks!

I do not have the problem and I cannot shed any light as to "why" you have the problem, but here are my best thoughts based on your info.
I often use iM6HD for quick iSight clips on MacPro using the iSight built into my LED Cinema Display. iM6HD works as well with my MacBook Pro. Both run SL.
I sometimes see strange color blinks in the preview window *before I begin to record*, but there is no problem while I am recording.
My inbuilt iSights shows up in the camera selection button just as it did in previous Mac OSs.
Have you selected "iSight" when you create your new movie project?
Are you observing the prohibition against running another camera apps when you open iMovie?
http://support.apple.com/kb/HT3095
Have you restarted the Mac?
I see you have tested in a "clean account". If that means a new user account, my only other thought would be whether a clean install of the OS with NO other software additions might give any insight?
If nothing helps, you may be right that there is something special about the new hardware.
If that is the case, why not capture your iSight video in SL's QuickTimeX? Then import the clip into whichever iMovie/editor you like for editing.

Battery Not Detected

I have a E420 (1141-CT0) & ran the System Update Manager and installed the battery firmware update that was advertised. Now, the battery is not detected. Is there an option to rollback a firmware update?
Thanks a lot
Chris

Hi Chris,
Welcome to Lenovo Community Forums!
Could you please confirm whether the firmware update was successful?
Try performing the below troubleshooting steps.
Unplug AC adapter and Shutdown the system. Remove battery, Connect AC Adapter and Start windows. Uninstall Microsoft ACPI-Compliant Control Method Battery from device manager under the battery tab. Shutdown, Remove AC Adapter, Install battery, Reattach AC Adapter. Now, Power up and check.
Ensure that chipset drivers are updated to the latest version.
Hope this helps!
Best regards,
Mithun.

ThinkPad T440 - Bluetooth headphones do not work

I have a ThinkPad T440.
It has Windows 7.
Issue: The ThinkPad T440 recognizes the headphones when i turn the headphones on. But the ThinkPad T440 does NOT pair with the headphones.
I have downloaded the latest drivers but the issue still persists.
The issue i'm having is NOT specific to the type of bluetooth headphones i'm using because the issue happens with any type of bluetooth headphone i'm using.
The headphones do work because i can pair the headphones to my iphone 5 and i can listen to music/videos on my iphone with the headphones.
Previously i had a ThinkPad T430 and the headphones worked fine.
Also, i do have a mouse that is bluetooth and the mouse works fine with the ThinPad T440.
My bluetooth radio is turned on.
In Device Manager, under Bluetooth Radios, it displays Generic Bluetooth Adapter and Microsoft Bluetooth Enumerator. Both of these have the latest drivers installed.
Does anybody have a solution to this issue?

Another forum enlightened me to the fact that T440s using Intel Bluetooth chips. This was the key to finding the secret sauce to get my Plantronics Voyager headset to work with a Lenovo T440.
The magic occurs when you head over to Intel's site and install the latest "Intel® PROSet/Wireless Software for Bluetooth® technology" for your platform:
https://downloadcenter.intel.com/SearchResult.aspx?lang=eng&keyword=bluetooth
In my case, it was:
https://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=24679&lang=eng
I'd then reboot as a safety measure. After installing it, there are no additional Start Menu items, but once you Add a Device from the Bluetooth Devices screen, all the appropriate device drivers for telephony and headset are automatically found.

S540 Battery not detected in Windows 10

HI All, Just upgraded to Windows 10, but I'm now finding out that the new Lenovo Companion or even the Lenovo Settings app will not detect the battery. I've installed the System Interface foundation etc. but to no avail. Battery is no longer charging to 50% , but to full and is no longer detected at all. Have any of you seen this happen too?

Good day and welcome to the community.
Please see the discussion in this thread:

There are some issues being addressed. Until resolved, you may wish to follow someotherguy's recommendation.

Why is my battery not detected?

EliteBook 8460p Notebook PC running Win7 Pro 64 doesn't detect battery. Boots and runs perfectly normal with ac power, but immediately shuts off (not shuts down... off!) when ac power disconnected. Also, when trying to flash BIOS update, ac power is somehow not detected. Help if you hae any ideas.
Thanks!

Turning off when you remove the ac power could likely be just a dead battery. How old is the battery? What concerns me more is that a BIOS flash will not detect that an AC adapter is connected. So it senses that the laptop is running on battery? What does the Windows power icon say (lower right corner)? Does it detect battery or say the battery is charging?

At first it didn't charge. But after doing a power reset, it charged up. And then I did a charge/discharge cycle. The problem is that right after I did my first discharge to break it in, the battery was not detected again. So I ran through everything. Power cycles. Uninstalled ACPI battery driver and reinstallled it to no avail Updated my bios to 1.80, since there's not 3.0 version for my lappy model. My old battery still charges though my laptop still tells me it needs to be replaced.
So...
Is there anything more I can do? Should I just return it and get a new replacement battery or is there still anything else that can be done? Was it just not compatible with my laptop even though it said it was? Any help would be great! Thanks!

Battery not charging, not being recognized, or losing charge
If it still doesn't work, there may be a problem with the battery or a hardware problem in the laptop itself.

Satellite A300d - New battery not detected

I recently got a new battery PA3533U-1B RS/AS for my aged Satellite A 300d.
When I place the new battery in the laptop, unplugged, press power button, the red battery indicator flashes several times, no power.
When i plug in the mains to the laptop, the red battery indicator stays red as-though charging, once windows has loaded the battery shows as Not Detected.
I have checked connection and gone through device manager- unistall/install but come to no luck. This is the 3rd replacement battery I've had from this company who have a very positive review. Is it my laptop or the battery?
I do have a good faithful 20 minutes battery that recognises every time and charges without a problem.
If you could please help it would actually stop me from going crazy, thanks in advance :)

Hi Paolo,
Thanks for your reply. I have kept the battery on charge for 12 hours +, both the 2nd and 3rd battery I have received, and neither of them show as detected.
When the laptop is off, new battery in, ac in, red light stays on for about an hour then it continuously flashes. This happens with both. After charging it won't turn on until insert ac, then when windows loads, bat not detected.
When I put my original battery in in turns on without ac, and battery shows and info correct.
I will speak to the dealer again, I returned the 1st battery, once i reported 2nd one faulty, he sent me a 3rd. The dealer has really positive feedback and good comment, it's just baffling?!
Thanks again for your help.

MacBook Spillage - Battery Not Detected! - Every Thing Else Works Fine!

_*Okay I Don't Know If This Actually Qualifies To Be Under This Category, But It Must Have Something To Do With The Battery. Here's What Happened_.*
I Accidently Spilt Some Orange Juice On My Macbook On The Keyboard And In The Hole Between The Screen And The Keyboard Area. I Went In A Big Panic And Started Mopping Up The Spillage, Taking Every Key Off The Keyboard And Drying It, I Even Ended Up Taking The Top Bit Of The Computer Off To Dry It.
After That Struggle And Drying Up Every Bit Of The Liquid I Tried Switching On The Computer After Numerously Pressing The On Button It Managed To Boot Up And Even Into The Login Screen. I Tried Logging In But I Got That Random Error Telling Me To Restart My Computer So I Did, Once Again I Pressed It Numerous Times, And Then It Started Making An Alarm Like Noise, Eventually I Managed To Get It On And Logged In. But For Some Strange Reason My Airport Card Was Not Detected, (At This Point I Should Say It Was Plugged Into The AC Adaptor), And The Battery Had A Cross Over It, Oh And According To IStat Menus My Computer Was Running At -128 Degrees C, Very Unusual!
Now When I Spilt The Drink My Computer Was Updating, As I Had Recently Reinstalled Mac OS X Leopard 10.5, So I Tried Updating And My Computer Shut Down, This Happened A Lot Of Times And Even Shut Down During The Hard Ware Test, But I Never Managed To Get The Apple Logo Telling Me My Mac Was Booting Into OSX. So I Shut It Down And Left It For About 2 And A Half Hours Until Trying To Switch It On Again, It Worked (Well Maybe I Should Say Works) Perfectly Fine And Is What I Am Talking Off Now, As This Tragedy, Only Happened, What 3 And A Half Hours Ago. The Airport Works, My Computer Is Not Running A -128 Degrees C, Except My Battery Is Not Recognised There Is A Cross Over It, Now I Would Test Another Battery But The Only Other Person Who Has A Macbook In My House, Is Asleep As Is Is 4.00 am, In The United Kingdom!
I Don't Know Why Only My Battery Is Not Working As The Juice Went Inside My Computer And You'd Expect The CPU Or Something Else To Not Work, It's Quite Strange!
*_If Anyone Could Give Me Some Advice Or Help With This Problem It Would Be Highly Appreciated!_*
*_Thanks In Advance!_*

Same thing happened to me,
I spilled orange juice on my Mac and after drying I tried to restart it,
it did, and then it would shut down and get error messages. I took it to the apple repair center and they said the motherboard was damaged. They actually recommended I just buy a new one, since replacing the motherboard would cost about the same. The battery doesnt charge, I have to use it with the ac adapter, and a few weeks ago, the hard drive crashed. I had to go and replace that. Then, the battery on my mac started to swell and when I took it in they said the battery had been recalled, so they replaced it. I just got it yesterday, dont need it since it wont charge, however this morning my mac started to shut down automatically, it did it over and over again until I took out the battery. Strange........... So far it hasnt shut down,
Thats my luck with my Mac,
Hope this helps
