AW M18x battery and AC power cycling need help

Recommended Posts

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.

Interesting problem, I had a few thoughts about this.

 

Have you tried playing with the pcie link state power management settings in the windows advanced power setting menu? I wonder whether setting it to off, for ac and battery could make a difference

 

Maybe try a different vbios for your 580m?

 

Are you running the latest chipset drivers for your machine?

 

I wonder how a different os would fare in this situation. I would try running Linux off a live USB and see what happens.

 

Or maybe create a partition on one of your disks, to install windows 10 on for test purposes.

 

You can get windows 10 licence keys off eBay for a few £ (which I've bought and activated successfully) not bad considering the MSRP of the disc sets with a key.

      Hi guys,
      i have m18x R1 model with A05 unlocked bios and i try to connect ati mobility 4870 card/s.
      I read ton of posts but people that seem to have similar problem with different card didn't post any solution. Case is when i connect 4870 i get black screen and 8 beeps.
      When i use only integrated graphics (no cards installed) laptop is starting normally.
      When i use integrated graphics (nvidia card installed as master) laptop is starting normally.
      When i use nvidia card installed as master laptop is starting normally.
      When i use nvidia card installed as master and ati 4870 installed as slave laptop is starting normally but in devices manager i see there is error 10 with ati card.
      When i use ati 4870 card installed as master i get 8 beeps and black screen.
      I tried to google for answers but unfortunatelly didn't find any. Do you know if that old card can work in m18x ? Maybe it's not supported at all? Do you have any ideas what else can i try?

      Hey guys, I have an Alienware m14x R2, and I have been trying to get access to the BIOS so that I can change the boot options (Everything is locked, I am unsure if someone set a password of if these are locked by default).I've tried updating the BIOS, and resetting the CMOS and nothing has changed this. Would anyone know if there are other options I can explore? Thank you.
