Can someone help me how to do it on a P157SM?  I am a total noob for now.

Is there a prema vbios already O.C for  gtx 980m?

You can see in the picture. I was having this issue with my old unmodded 180w PSU as well.

Really?? So I need a 330w PSU? It only turns off if I use Premamod vbios, without tweaking the voltage.

Hi, I tried to solder the original plug-in jack of my 180w PSU to a DELL (  Flextronics) 240w PSU. I connected the ID wire to the ground and white to white as you instructred, but the Adapter shuts down 1-2 min after GPU is under full load. I have a Clevo P157SM and upgraded 2 summers ago to a GTX 980M which needed more power. It is only doing this while using prema's vbios. I didn't change any settings. My laptop was working well with the 180w as well, but many users reported that it needs more power. Need a bit of help. Thanks!

I have a problem with the vbios.. If I stress the gpu it will shut down the laptop and also the PSU. I modded a 240w PSU in order to work for my Clevo P157sm which originally came with a 180w PSU. I had this problem with my original PSU as well...I thought it would be a power issue but I guess I am wrong. Any ideas what could it be? Thank you!

Hello, 

     I have a Clevo laptop with win 10 64-bit and a gtx 980M. My laptop has optimus, I had a driver 373.xx something that worked flawless, but now I had to reinstall the driver because optimus wouldn't work anymore. I forgot which inf files to change, nvcvi and there was another one, but I can't find which one, could you please tell me? Thank you!

Thank you! I found the problem yesterday, it was a gpu monitor gadget.

How to enable optimus on a clevo p157sm? The LED for it is always on and it's draining my battery quite fast. I have a 373.06 driver installed and latest Intel HD graphics. Should I do something in BIOS? Are the modded drivers faulty? I have a replaced GTX 980M on it. The laptop came originally wih a GTX 780M. Thank you!

I saw on some posts that there are some v3 prema bios. Is such the case for Clevo P157SM & GTX980M 8GB? I can't find them on prema's website. The reason I need it is because optimus won't work on my laptop with windows 10 64-bit. Thank you!

I see, wasn't sure about it. I checked some of the PSU mods out here some time ago, I ordered yesterday a new DELL OEM 240w PSU, I will change the Jack and let you know if it solved my problem!

Yes, I use them both. I have been using the prema mod BIOS for the system for a few years now with no issues...

Unfortunately, no.

Hello,  

         I recently tried to overwrite my stock BIOS with the V2 PremaMod BIOS for my Clevo GTX 980M and the latest NVIDIA drivers( 373.06). Everything worked great until I enter a game, after about 1-2 minutes the laptop shuts down and the LED located on the power supply also turns off. My laptop is a Eurocom X3 ( P157SM) which originally came with a GTX 780M and I still use the 180W Power Supply from them, could this be the problem?

        I didn't try to overclock anything because I know 180w is simply not enough. If I use the stock BIOS again, everything works back again.

Thank you!
