I have looked at the forum posts regarding the "0190 critical low-battery error" boot up problem, but mine seems a little different. My problem with my T510 Thinkpad (Windows 7, 64 bit) is as follows:
(1) When I attempt to boot up with the AC adapter only (no battery) I get the 0190 error. The T510 afterwards shuts down immediately. I cannot seem to get into the BIOS by pressing the ThinkVantage button to interrupt the boot up process.
(2) When I put in a good battery, even one charaged at only 10-15% or more, then I can boot into Windows with no problem. My T510 must have a battery in place in order to boot up. The AC adapter alone gives the 0190 error as mentioned. (my AC adapter is standard Lenovo issue).
(3) One would think this points to a problem with the AC adapter, but it's important to note that my battery will still charge up to 100% if the AC adapater is plugged in! Therefore, the adapter is not totally disfunctional. While the machine gets the 0190 error on the adapter alone, the adapter is capable of charging the battery.
(4) I should note that I'm using the latest BIOS v.1.5.2 for the T510, as of June 29, 2015.
(5) Note also that others with the 0190 issue seem to have the opposite problem. Namely, they can boot up with the AC adapter only, but have trouble with the battery in place.
My questions: What can I do to get rid of the 0190 error when not using the battery? Is there a motherboard problem? Is the problem only in BIOS?

Welcome to Lenovo Community!
This kind of issue occurs either with power circuit of the laptop or with the power adapter, is there anyone who is using the same model laptop, so that we can verify changing the adapter.
This might not resolve the issue but you can check with performing power drain. To perform please remove the AC power adapter & battery, after that press and hold the power button for 30 seconds perform this step for 2 or more times.
Hope this helps. Do post back if issue persists!

Thank you for your suggestion. I have tried the power drain, which I had seen suggested elsewhere, but it did not work for me. I will attempt to pull the CMOS battery as another user suggested, and will return with the results. Having never done such a think on a laptop before, I'm not sure how difficult this will be.

The CMOS battery will available under the keyboard you have to remove keyboard & keyboard assembly to get the CMOS battery. Use the below link for further assistance.
Hope this helps.

Hi there forum!
Just experienced this error on my T540p. Tried the power drain a couple of times which resulted in the laptop completely unable to display the error message. As always great timing! As frustrating as it is, we must remember not to take it out on the machines or the manufacturers! At this point suspect the issue is related to the CMOS battery as suggested in previous posts - is it the CMOS or another part down/up the line? Will update with the ultimate resolution. Thanks for the tips.
