M15x not starting at all, no lights nor fun starts

Recommended Posts


my M15x seems dead for no obvious reasons, simply one day worked, the other day not. No liquid inside. Battery is very old so I use notebook without it.


The symptoms are that it does almost nothing. When I press power button, nothing happens. Sometimes, when I hold the power button, it blinks twice (the power button only).


After some checks I suspected the motherboard so I bought a new one from ebay, reinstalled everything but it behaves the same. It could be faulty too but the probability to have two motherboards with the same issue is very little.


I tried to run it without RAMs, with different AC adapter, no change. Now I'm guessing that the CPU could be dead. But don't want to waste another money just like that so I hope someone from you, experts, could face the same earlier and I can learn from it.


Do you know how M15x behaves when CPU is completely removed? And what if GPU is removed? This could help me to isolate the origin of problem.

Hi mate not sure what use ill be as mines was a little different to yourself. My dad thankfully has the m15x as well. So i tested all my main parts in his the gpu, cpu, mem hard drive, wifi card and power strip and stuff. 


Em it could be a number of things man . Is it just the alien head power button thats flashing , no num lock keys or that ?


Try the laptop without the battery in it, just the power adapter, do a discharge with the batter out first tho, take battery out leave unplugged and hold the power button for 20 seconds. 


Wouldt think the same issue with both boards but u could try removing the cmos battery under the back panel and then do a discharge, reset the bios see if thats causing the issue.


Were u over clocked at all. Whats the spec of the laptop mate, heard alot of peoples crappy out on the 260m gpu,


Also is there any lights at all on your power adapter, still glowing blue ? 


all i can think off without more info basically the stuff i did with mines

Thanks for your feedback and suggestions.


I tried all the reset options and also I re-installed all the components to a new motherboard. Unfortunately no change. With battery in the power button (alien head) is flashing but the battery is really dead so it has no chance. Without battery it flashes twice only. When  I press the power button, flashing stops, I can hear very little "clap" from the area where the power adapter is connected to the motherboard. But no LED lights or blinks, simply no activity at all. Adapter still glowing blue, I tried also another adapter, same.


And I do have the crappy 260 GPU. But I assume if this is dead, the CAPS/NUM/SCROLL LEDs should blink, there are some error codes to show that.


When you tried to replace components in your M15X, by a chance, did you try to run it without CPU or GPU? Did it anything or nothing at all? I'm asking because it seems to me that CPU could be the reason of this behavior. Battery charging works without CPU. But to activate motherboard, I guess only two components are mandatory: motherboard and CPU. If I disconnect all the other ones, motherboard should start and to show some error codes (see attached).

id assume it would power but display a black screen without the cpu, possibly even beep. As for the gpu i assume the same. You can pick up the i7 720 for super cheap, but i cant say it will solve your problem. 


My one was worse than yours, i didnt get any power at all, not even the alien light, so i cant say for sure what it would do without those components, but from what i read, sounds similar.

Just wanna share what happened to my m15x about 2 years ago, recorded and uploaded to youtube (See below)


Issue / Caused / Solution : Forgot to lock the CPU socket on it, silly mistake! :)


Good Luck!

Thank you all for your inputs.

I did some further tests and it seems that the motherboard tends to boot (alien lights for 10 secs, then switches off automatically). When I insert VGA, it does nothing. Therefore I guess the VGA is dead. Will try with another one and will see.

I'll share results later.

      I have a p150sm which has a seemingly dead 780m due to a perpetual error 43 which came after a big BSOD about 6 months ago. I upgraded the laptop to a 980m and modded the inf files. The upgrade was perfectly fine for a week. One day, i left the laptop and something related to sleep or power may have caused the laptop to shut off. Since then, the laptop with the 980m won't boot. I tried many things like resetting cmos, taking out the hardware and putting it back in, and resetting bios, and buying a 230W adapter. Nothing worked. The laptop works fine with the old dead 780m in there, but now when the 980m is in there, holding the power button generates a green light flash and then the power LED goes back to orange. No sounds, maybe one tick, and that's it. What is left to try?

      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!

      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?
