Question about IBM ThinkPad T20 2647 Notebook
I have ibm thinkpad this gives 0190 error. how solve this
If you pull the battery out and turn it on with AC power only it should still work.
This however is not the case in my situation.
I have a t61 lenovo and it is giving the 0190 critical-low battery error and it does this even when the battery is out, and plugged into the wall with the AC adapter. I am not sure, but could it be the CMOS battery causing this problem?
I dont know for sure, but i think my motherboard is hosed.

Error 0190 means you need to charge your battery. Either your battery is not charging properlty or your charger is not working anymore. If the computer works while plugged in and gives no error then it would be the battery that needs replacing. If the battery is a few years old then you may want to order a replacement. The Thinkpad A31 uses the ThinkPad Ultrabay 2000 Li-Ion Battery. You can purchase a replacement battery from this website:
If the laptop doesn't work while plugged in and you dont get any lights on the battery or power indicator on the front of the laptop then you may need a replacement. Depending on which region you are in you will need a different A/C adapter. You can find a list of different A/C adapters here.The A31 uses the 72 watt power adapters on this page:
I hope this helps.
