My laptop shutdowns after boot on battery and is unable to boot up again unless the charger is attached. The battery is new and it has something to do with the Speedstep. When I disable it, the laptop does not shutdown immediately after boot, but this significantly increases the boot time and obviously uses more battery.
My other option is to enable both Speedstep and CPU performance mode in the bios to avoid this but the CPU frequency and utilization is inconsistent/unstable causing the temperature to raise. Either way the laptop shutdowns are inevitable if on battery (however sometimes lasts till 20%) and refuses to power up unless plugged in. The CPU also seems to randomly get stuck at 800mhz randomly when the CPU performance mode is disabled.
