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.
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!
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?
I've read a lot of conflicting posts about thermal pads for the CPU and GPU on the Alienware m15x. There are a lot of pictures out there detailing all of the different sized thermal pads that you need. In my experience, 1.5mm pads are perfect for everything on the Dell 980m and the 920xm. I was using 0.5mm pads at the time that I replaced both, so having the exact sizes was important. I think that I might have actually fried my 5850m in part due to not having thick enough thermal pads. I discovered that they had had not been making contact with the heatsink at all.
I tried following the guide on techinferno and noticed that my gpu was actually bending (a lot) and certain areas weren't even making contact at all. I tried different layering of thermal pads through trial and error, looking for imprints of vrms and such. 1.5mm on everything worked the best.
Some people are putting thermal pads on things that the manufacturers don't even put them on. I can't say what thicknesses are needed for these, but it will be more than 1.5mm.
Anyway, I hope that this helps someone. I was using Arctic brand 0.5 thermal pads and stacking them in my testing. I have 1.5mm pads on the way now.
