Hi, i have a lenovo t480s with bios pass, the back case is down and save that while I got the programmer. Now i go pwr on and that no power, the battery is full charge. When i try pwr on only led pwr one time and off and no never turn it on again so that it turns on again I must disconnect cmos and connect again. With the charger connected, there are times when the power LED turns on twice, sometimes once, and sometimes 3 times. Please help
