m15x with new 770m driver wont install

Recommended Posts

Hi guys,

 

As the title say i have an old m15x with a 920xm, 8gb ram and just got a 770m to boost gaming perfomace but the drive wont install.

 

When I run GPU-Z I see the attached image which are all the correct stats of the card but not really the card and HWINFO64 is showing that its the correct card but again not anything else.

 

I've read about .inf issues and about vbios flashing but dont know how to do either or which would be best to try.

 

Any ideas which (if either) could be my problem and how to do either task or how to go about more trouble shooting. Any more info required just ask. Any and all help much appreciated.

 

I just want to play total warhammer:-(

You have to "Simulate" that there is an existing M15x with a GTX 770M on the market, with the modded .inf

      I reversed the input polarity on my m15x jack after a botched psu repair. Computer worked fine, but overall power control is messed up. System only boot on both battery and psu, no battery charge, and a very low battery drain (arround 6wh).
       
      I aways had battery issues whith my 8 years old m15x after my original battery died. Bought a new one two years ago, didn't work. Checked on upower, basically no info on manufacturer, power or history. So i refunded and used the system hooked on the psu as usual. In August i bought a new one, worked flawlessly for a day. The next day the battery died from nowere. Checked upower, bus was ok, battery was charging extremely slowly (6wh), history showed subpar disharge before shutting down. I got mad at this point, decided that psu was to blame. Opened it, checked everything, noticed some wear on the male jack. Resoldered it, connected on computer. Nothing happened, so i checked the voltage. That's when i realised that i screwed up big time. I swaped the positive and negative wires. Decided that one mistake was enough, so i sent my m15x to a trusted repair shop (latter found that they just hooked the battery and gave me back as soon as it booted, they didnt even open it). Got my pc a week later, but the battery didn't charge . Worse, it was slowly discharging (same 6wh as before), and it needed both the psu and the battery to turn on. At 65%, it worked as usual for my college semester, but the battery is dead, and so is my computer. I bellieve i burned some voltage controller or something. I'm pretty competent at soldering thing's (evem smd components) when i know what to do, and i can understand simple circuit's, but when i got my hands on the m15x datasheet i got overblown. I cant make heads or tails about it. I aways lurked this forum and i bellieve your guys are the best when it comes to finding creative solutions to technical problems concerning microelectronics. I followed a guide in this forum as a teenager to upgrade this same computer to a gtx680m, overclocked stuff, got custom bios, and had a lot of fun learning. The m15x is a deprecated platform, but it's a part of my history that i dont want to let go.
      So please guys, help me.

      Hi guys,
       
      I'm sorry for making another thread just for this but I really wanted to pick your brains on this!
       
      I have an m15x with a 770m running windows 7 and everything works. Rock. Solid. I'm pretty happy with it. Since windows 7 is on it's way out, I would like to upgrade to windows 10. Now I've looked into it before and had a really hard time getting the 770m to behave nicely and had all these issues with green/yellow/pink screens and I remember it being a miracle I got it to work on 7 as good as it does.
       
      My question is how well does the 970m install vs the 770m - particularly on windows 10? I would buy it in a heartbeat if it makes the install less tedious with the colored screens and all that. Especially if all the functions work on it! I have been searching the internet and I cannot find nearly as many problems with the 970m as I could with the 770m, or am I just  not looking in the right places?
       
      Thanks a million!

      Hello forum, i have a problem.
      I own a P370EM it had a 7970m but its not working anymore. I bought a GTX 770M to replace it. But after changing the cards, after POSTing the screen goes white even though the pc boots into windows normally. What may be the issue?

      Hey all, just got my m17xr4 and put my 980m from my m15x (old) in it. I was able to score much higher graphics score in firestrike even though it is a much older machine. I made a custom vbios for the m15x to get rid of any throttling, and am in the process of making on for the m17xr4 but I'm wondering if there is anything else I have missed to deal with the throttling. any help would be appreciated

      Hey all, decided to get a cheap m15x and managed to get an msi gtx 980m along with it. I've ordered two fans I'm planning on trying to mod in, one being a 13 cfm dell m6700 fan and the other a 11cfm m4700 fan to try and help with the heat. I currently have a 210 or 240 watt? power adapter and a 920xm installed so I'm planning on undervolting the gpu. Is it best to do this inside afterburner or is better to do try and mod the vbios? Also will I have to flash the dell vbios onto my card to get it working with my system or will I just have to modify the .INF file?
