I recently purchased a replacement 980M (Clevo model) for my P770DM-G after the original died, however, after installing the card the laptop doesn't boot. I only get a black screen, and after a couple minutes the fans spin to max before shutting down, which is the same thing that happens when I try to boot it without any gpu at all. I've tried the reset procedure, unplugging, removing battery, and removing CMOS, to no avail. It does beep before shutting down (I counted 22 times exactly). Anyone have any insight as to what the problem is?
i have m18x R1 model with A05 unlocked bios and i try to connect ati mobility 4870 card/s.
I read ton of posts but people that seem to have similar problem with different card didn't post any solution. Case is when i connect 4870 i get black screen and 8 beeps.
When i use only integrated graphics (no cards installed) laptop is starting normally.
When i use integrated graphics (nvidia card installed as master) laptop is starting normally.
When i use nvidia card installed as master laptop is starting normally.
When i use nvidia card installed as master and ati 4870 installed as slave laptop is starting normally but in devices manager i see there is error 10 with ati card.
When i use ati 4870 card installed as master i get 8 beeps and black screen.
I tried to google for answers but unfortunatelly didn't find any. Do you know if that old card can work in m18x ? Maybe it's not supported at all? Do you have any ideas what else can i try?

I bought Dell gtx 880m for my m18x r2.
I thought there would be fewer problems than with gtx 970m.
Installed it and the laptop at the start produces 8 sound signals with black screen.
I tried to flash a11 and a12 BIOS and it did not help.
Hey guys. So I got this far.
Connected the laptop HP EliteBook 8460p i5 2450M to this ASUS Geforce GTX 750 Ti 2GB GPU via an express card /34
And this resulted in my laptops display not initialising which was to be expected I recall reading on different threads here.
My second monitor is using hdmi so I tried hdmi on the gpu and also connected a hdmi to dvi adaptor to the laptop and sadly the monitor never detected anything,
Can anyone help make sense of this with me?
BTW I connected the egpu while the laptop was off. Then powered the laptop on
I just posted on the Prema Mod blog, and just realized my misstake... I will kindly ask for my comment to be removed, as i feel right here on Techinferno is a better place for my question.
I have a P150SM-A / GTX970M with stock BIOS. Had to shut it down to reboot, and when it turned back on, the BIOS kicked in in “recovery mode”. I pressed continue, and after some progress bars it rebooted. Now, it won’t turn on at all anymore: the fans are both ON, the keyboard is backlit solid blue, but that’s it. No screen backlight.
I have tried numerous things that were asked here: Removed the battery, power plug and CMOS battery and let it sit for 10mn… Same thing. Tried to change RAM slots, but no cigar…
Is there anything i can do before going to my reseller?
I don’t have an external screen or rig to use unfortunatelly, and i would really appreciate any direction.
- When the computer went into recovery mode, I noticed that the HDD identifiers were different, before they were P0, P3 and P5, but this time change to PM SM and SS (So primary master, secondary master and secondary slave… Reminds me of my first PC with IDE back in 1998).
- Also, before doing this, the computer took an abnormal amount of time before showing me the BIOS (Like it was stuck on detecting some hardware). I also remember briefly seeing a message about an invalid EFI thing… Which is super weird as I dont use EFI.
- When i turn the computer on, I noticed that Caps Lock / Num Lock are not functional. However, Fn + 1 puts the fans at full speed. Not sure if this information is of any help.
- Im aware of the method to Fn + B to recover a bios, but I'm not too comfortable doing so, as it might break the warranty, yes?
Thanks for your help!
