SuperMG3 Posted yesterday at 01:27 PM Share Posted yesterday at 01:27 PM (edited) Hello. My M18X R2 laptop was working fine. I got back my MXM card from X-Vsion. It booted and was detected on the bios as NVIDIA GFX but I forgot to connect the storage cable in order to boot to windows and test. After inserting the cable. The pc did 5 beeps (CMOS?), I restarted it and it did 7 beeps. How is that even possible? I removed the MXM GPU, still the same thing. I reset the CMOS but I still have the same issue. I removed the RAM, still 7 beeps or... It powers then shutdowns 2 seconds later... I removed the CPU, same 7 beeps. I replaced the CPU, same 7 beeps. I flashed by old bios backup to the Winbond bios chip, still the same issue. I never got the 5 beeps ever again. I tried holding the D button to get to the screen diagnostic test but it never happened. I removed the cmos battery and power it on again, it just powers on and shutdowns 2 seconds later, I heard no "5 beeps" By the way all of the LEDs are working when I start the computer... Rarely tho, the LEDs are off when doing the 7 beeps... So you're telling me a SATA cable destroyed my laptop?

SuperMG3 Posted yesterday at 01:50 PM Author Share Posted yesterday at 01:50 PM (edited) The laptop keeps shutting down 2 seconds after I power it. The LEDs light up. I "tested" the NVIDIA RTX 3080 MXM on my Clevo X7200. It was detected on the BIOS, I rebooted again, it was still detected and the laptop started to do the 2 beeps noise on the bios screen because I had 0 cooling on the GPU itself, it was a test to see if the GPU was in cause but no. I put back the Nvidia P5200 GPU and the X7200 still works... I maybe think the sata cable rekt the alienware's motherboard?

Rengsey R. H. Jr. Posted yesterday at 05:14 PM Share Posted yesterday at 05:14 PM That’s some weird stuff there. I have never heard that it would mess up the system. Most likely the mobo is fried. Link to comment Share on other sites More sharing options...

No display, just 7 beeps or just shutdowns 2 seconds later after powering it up... There's no way a simple SATA cable that can power 3 HDD/SSD fried the northbridge or PCH...

SuperMG3 Posted yesterday at 06:30 PM Author Share Posted yesterday at 06:30 PM (edited) Hello, some updates. My SSD and HDD are working fine after the incident. I still have no idea how these got spared but the motherboard didn't. I also had a smart plug plugged in. Now the smart plug can't close its circuit. I click on the power button, won't shutdown... So did the PSU destroy my computer? The smart plug works but you can't shutdown it anymore, I don't hear the CLICK noise when it switches off/on. But the PSU was working fine. I shutdown the laptop, I remove the PSU cable then I plugged the sata cable, I plug back the power... and everything went bad. I tested the PSU on a Dell M6700 and it works, maybe from now... Laptop didn't commit suicide when I unplugged the PSU. Edited yesterday at 06:49 PM by SuperMG3 Link to comment Share on other sites More sharing options...
Rengsey R. H. Jr. Posted yesterday at 07:10 PM Share Posted yesterday at 07:10 PM The only option left is to “ blind flash “ the motherboard and hopefully it wakes up. Link to comment Share on other sites More sharing options...

Naberius Posted 17 hours ago Share Posted 17 hours ago It definitely _sounds_ like motherboard. I'm dealing with something similar on my m17x r4 where it powers up to 7 beeps. That said, if I press the power button again (prior to or during the 7 beeps) it dismisses whatever exception was preventing post and just... posts as normal... worth testing for the sake of it but they're very different laptops...

sliderfra Posted 12 hours ago Share Posted 12 hours ago Dreaded 7 beeps are mostly pch / chipset failure. Usually BIOS corruption is 1 beep and can be resolved by blind flash (or ch341). Link to comment Share on other sites More sharing options...

I don't have the 7 beeps now it's random. I now get the "shutdowns after 2-3 seconds of being powered on" Link to comment Share on other sites More sharing options...

Fans kicks in for 5 seconds then system powers off. When I put usb in another port (instead of eSATA) it doesn't shutdown, fans kick in but no beeps or restarts. It's not a bios problem because the laptop remembers the RGB theme I applied too even tho (the flash bios also had the green theme) Edited 4 hours ago by SuperMG3 Link to comment Share on other sites More sharing options...
SuperMG3 Posted 2 hours ago Author Share Posted 2 hours ago (edited) I killed two Alienwares. One was a M17X R4 because of swapping MXM cards and I used a defective FirePro card that made the video controller die (no display on iGFX and MXM). So it's understandable. But for the M18X R2? A SATA cable? Really? The fact that my Wi-Fi card and the SSD and HDD are still working, it's insane. (Because they were all next to the sata connector). Yesterday before the PC dies, I was testing some dead AMD MXM cards. 3 of them, 2 are dead and 1 artifacts but the pc didn't die when testing them. Then the next day I try the RTX 3080 MXM I got from repair, card is detected. Then I plugged the sata cable and here we gooo... (By the way the PSU was off and no battery connected into the laptop) By the way all of theses cards I mentioned (expect the firepro) were tested into a Clevo X7200. The Clevo didn't die. So Alienware is low quality? Edited 2 hours ago by SuperMG3 Link to comment Share on other sites More sharing options...
