T480- CANNOT find compatible external battery

Q: T480- CANNOT find compatible external battery

Hello Lenovo community, I need assistance regarding finding compatible external batteries for the T480. So far I have found 2 compatible T480 external batteries : (1) https://www3.lenovo.com/us/en/accessories-and-monitors/chargers-and-batteries/batteries/BATT-BO-Thin... (2) The second battery is the 72 watts also called "61++" However, after contacting chat support, we found that the battery was not listed. Only the 24 watts were listed. If anyone is searching for the part number for the 72 watts' battery, the number is "4X50M08812" I am posting to save other "T480" buyers' time if they are having an issue finding the 24 and 72 watts' batteries. Lastly, if anyone comes across other external batteries that are compatible with the T480 that I have missed, please help me us out by adding to this post. Sincerely, T480 Enthusiast

I have a HP Envy dv6z, which came with a AMD Radeon graphic display card. I have a HP 2009m external monitor. On Windows 8, everything worked. When I upgraded to Windows 10, my external monitor is no longer detected. From I have learned, it does not appear that HP or AMD is upgrading the driver for Windows 10. If this is not true, please let me know where I can find the new drivers. I believe my only option is to buy a new monitor. I have these questions ... 1. Recommendations for monitors that have drivers compatible with Windows 10?2. Will I have to replace my graphics card (assuming AMD will no longer be my graphic display)? Any other thoughts or ideas are welcome.  

A:How to find an external monitor compatible with Windows 10

We need the full model number of the laptop but I suspect that when you upgraded to Windows 10 your video is now running a generic driver that does not support the HDMI port. Go into device manager and see what is shown for "display adapter" please. The problem is not the driver for the monitor it is the video card driver. There is no way to replace the video card. We just need to get the right Windows 10 drivers installed to make the external monitor work. It is connected by HDMI, right, not VGA?

I have been having issues with my battery on my T480 lately. I will have the laptop running around 50% battery and sometimes try to restart it but when I do, the laptop will not power back up. The Lenovo bios screen will post but when the Windows 10 circle starts spinning the computer fully shuts itself off and loses power and I cannot turn it back on until I plug the charger in, but when Windows loads it says I have battery. Yesterday I was using the laptop and when it went from 50 to 49% battery the laptop fully died and shut off and would not power on again until I plugged in the charger, yet showed 49% battery when Windows loaded again. I have been working out in the cold with my laptop and I am not sure if that is or has affected it some how but I can't keep having these types of issues when I need to be able to use my computer in the field. I know Lenovo used to have a tool to reset and deplete and recharge the battery, does this still exist? I ran the diagnostic tool but it finished instantly saying both batteries were fine with a time on the diagnostic of 0 seconds. Not sure if there is another tool I can be using to try and get this working properly again.

Hi, I bought a T480 back in March 2018 and the first thing I did was to put 32GB RAM ( 2 x 16GB Crucial CT16G4SFD824A.C16F).   I always found the battery life to be low... Around 4h in a youtube video playback loop.  I would kill it faster than that doing "real work". Yesterday, as a test, I remove the 2 memory stick and put back the original 8GB that came with the laptop. It seems 32GB kils the battery more than I expected. With low level brightness and idling, Lenovo Vantage gives me those number for the power draw (in Watts):32GB:  Around 7-8 Watts8GB: Around 3-4 Watts My question is: Does having 32GB really consumes that much power?  I've read that some have issues with the Crucial memory where they use more power than they should (low power). Anyone with 32GB can confirm their battery life is impacted that much or not?  And if not, provide the model of the ram, I'll order some!  Cheers.

A:T480 Battery Gauge Reset Issue

I have stopped the reset on my T480 several times due to work interruptions and not seen and bad side effects.In your case there seems to be some error condition anyway, so I'd stop the reset let the battery discharge by a few percentage points and then try it again.

In Lenovo Vantage I"ve been getting some strange readings from my second battery. Every 3 minutes or so the second battery's status display goes blank and I lose most of the battery's information readouts.Some how I don't think this is normal activity and it seems like the battery is losing it's connection to the computer despite the fact that the battery's charge status is still being reported in the windows power widget. In addition the internal battery seems to like to drain first instead of the hot swap battery. I've read several forum posts on how Vantage drains from the battery that has more wear first but the internal battery has drained 3 times and the external has yet to drain first. This is what the battery status looks like in between these "grey out" episodes.I'd appreciate any help.

I bought a T480 with an HDD, but I've since bought a Samsung 960 Evo and installed it into the laptop bay, and I want to clone the HDD to the SSD by booting from the HDD externally, but that doesn't work. I'm using a Sabrent USB 3.0 hard drive adapter kit to power and connect the HDD externally. I looked around for solutions just can't boot the HDD externally, even after going to BIOS and disabling secure boot and changing UEFI/legacy boot option to both.

A:T480 can't boot from external HDD?

Usually one must format the SSD before use, then connect it with a USB adapter to clone the existing HDD to it.
 
Steps that I employ...
 

Purchase SSD
Read SSD user guide, download manufacture software
Format SSD using manufacture software
hookup SSD to target computer via USB (notebook) or SATA (desktop)
Clone HDD to SSD via manufacture software / thrid party software
Verify information on SSD matches HDD
Remove HDD, replace with SSD
Boot the computer (notebook) verify installation / cloning works
Store HDD in safe location (as back up device)

This procedure works 99% of the time, but there is always the 1% that I have to work around otherwise.
 
Good luck.

Even though I have about 80% battery, windows thinks I have 44% only. This is bad because when one of the batteries gets discharged, windows decides it has reached critical levels and hibernates the system. This started happening after I enabled battery charge threshold and set the batteries to charge only until 80% and only when below 40%. I tried uninstalling the batteries from the device manager but it didn't help.

On a few previous occasions, while running my Lenovo Thinkpad T480 running Windows 10 (10.0.17134 Build 17134), it shuts down without any prior notice nor warning, loosing any unsaved data. Each time it occurred, the machine started up just fine when powering on, still on battery only.It wasn't until today that I came to learn the reasoning. Prior before the unexpected shutdown, I had seen that Battery 1 was at 5%, and Battery 2 at around 80%. Minutes later, the laptop turned off without any warnings. Once rebooted and still running on batteries only (not plugged in), the battery status shows: Battery status after rebootIn other words, my laptop does not switch over to the secondary battery as soon as the first one runs out of juice.

Hi everyone, Title says it all, I know this topic of discharging internal battery first has been brought up a lot, and that the reason behind it is this: The T470s are designed to drain the battery with least wear first so as to degrade both batteries equally and prolong the laptop's overall battery life. However, as I'm using a new 61++ battery, clearly somethig is going wrong somewhere as the year old internal battery cannot be in better condition than the brand new external.https://gyazo.com/6c12f3f40514599d04d852a8589189ab Any ideas? Thanks!
