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?
Hi Guys, may be someone could give me a good advice...
Alienware m17x R4 with 120hz panel form r3 (LG - LGD02C5)
Bios Dell A15 (Also tried unlocked A11)
Now installed GTX 860m 4gb (Kepler edition) works with no issue
Bought GTX 970 6gb Aetina production Works under MS driver Does not show image on eDP internal screen right after installing Nvidia modded drivers All external ports ( HDMI, eDP VGA) works with no issues - tested on benchmarks the card itself works great The internal screen could blink several times depending on vBios flashed ( so the card is trying to fire it up) Internal screen is not recognized properly - Using Monitor asset manager i observed that: GTX 860 create two monitor entries 1) Realtime and 1) Registry GTX 970m creates two monitor entries 1)Registry and 2) Registry If I change the max Hz using CRU to 100 and Close/Open laptop screen it will show picture in 1024x768 resolution with no possibility to extend and it also see a "Virtual monitor" attached to real one ( extended)
So the main issue is that INTERNAL Display is recognized AS 2 displays 1 connected to the internal laptop port and one into Display port:
vBios tried Premav2, MSI,Dell,Clevo Drivers version tried: 340,350,380,411
I searched for a something related to my issue here and found themes which are really near - but with different problems
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.
