I have an M18x R1 running WIN7 PRO NV580M SLI, however second card was removed due to possible issue. I am running Ahmeds Unlocked BIOS A04. Since I removed the second card I am getting a power cycling issue, the battery charges fine and the system runs fine off AC power but when connected to AC with the battery in and as soon as the battery reaches 100% it starts cycling between on battery power and on AC power. I have performed a system restore. Restored to stock BIOS then back to unlocked BIOS. Pulled battery connected AC and then put battery back in when windows boots. Ran a power drain by holding the power button three times. Booted on battery alone, then booted on power alone. Nothing has worked. I am hoping someone has run into this issue and can help me. This is a new system to me and has some differences of the M15x I used to have.
