becks21 Posted May 20, 2016 Share Posted May 20, 2016 Hi there, I have a P150EM (i7-3612QM) with stock BIOS and for several reasons I want to use my Laptop without a dGPU installed. When I remove it and boot up my system, the LEDs start flashing, a beep sound occurs, the fans turn max, and finally after approx 30 seconds the Laptop shuts itself down. How can I prevent from this behaviour? Is there a mod or something? Thx and Cheers Quote Link to comment Share on other sites More sharing options...
Khenglish Posted May 20, 2016 Share Posted May 20, 2016 (edited) Unfortunately the p150em embedded controller interprets no gpu temp sensor reading as an overheating gpu, and it shuts the laptop down. There is a hidden bios option to not power up the dgpu. If you have a dgpu that is functional enough to let the laptop run, I can try this setting on my laptop. If it works I'll send you a modded bios. It may even allow no dgpu at all, but I doubt it. If that doesn't work, we can try pulling components from a dead gpu to make it draw no power and not need a heatsink or fan. If you have a dead card let me know what it is and I can point out components to remove. Edited May 20, 2016 by Khenglish Quote Link to comment Share on other sites More sharing options...
becks21 Posted May 20, 2016 Author Share Posted May 20, 2016 Thx for your reply.. My dGPU card (AMD Radeon HD 7970M) is fully functional.. It just gives me a hard time on Linux, where drivers are a mess. What about the PremaMods BIOS' I read about.. do they expose this "hidden option" ? Would I be able to go back to stock BIOS or to enable/disable dGPU from BIOS menu ? Quote Link to comment Share on other sites More sharing options...
Khenglish Posted May 21, 2016 Share Posted May 21, 2016 Prema bios doesn't have the option in menus. Its something hardset behind the menus. You would need to flash back to a regular bios for the dgpu to work again. I can probably try it out for you tomorrow to make sure it doesn't cause a brick and actually works.
