Check if the battery is already fully charged. If it is, the charger will stop charging when battery is 100% charged.
You can check this by unplugging the charger cord from the laptop. If the battery is not fully charged, plug in the charger cord into the laptop again, start the computer and enter the BIOS. In the BIOS, look to see if you have a "battery check" and start it. This will test the charging and discharging cycles of the battery.
Hello, The CMOS battery supplies energy to the Real Time Clock when the computer is not connected to the electrical socket, and does not have the battery inserted. It should not prevent the computer from starting up. You will however be asked to reset the time and date of the computer. Hope it helps.
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:
