Hello I have an IBM Thinkpad T20, The Thing Turns On and Works Fine, But it Doesnt Charge The Battery, Also the battery light keeps Blinking Orange and the none of the lights stay green, it just blinks green once when i turn it on and then changes to the orange blinking light on the battery icon. i hope that i dont have to change the system board because its expensive no matter where. The power adapter i think is different because i took it from an older thinkpad, the voltages seem to be exactly the same, the Thinkpad has 16v = 3.36A and the power adapter says (input 100-240v~1.3A-0.7A) 50-60 Hz (Output 16v 3.36A) I Also tried some HP Adapters. Please Help I Want To Get it to Work. Thanks (I Think The Power Adapter That Im Using Is 56 W, and The One it needs is a 72 W, Would That Cause This)
