NP5793 Boot Failure

I had purchased a Sager NP5793 from XoticPC, as many of you here already know. After almost 2 years of working perfectly without any issues whatsoever, I am now facing a major issue. Last night my roomie was using my laptop, gaming. He smelled something and saw that his own laptop's adapter was heating up too much so he shut it down. I believe there was high voltage and voltage spiking last night. And after a while my laptop suddenly just switched off. Till now, it hasn't been able to boot. When I press the power button, it lights up and then there's no audio or video. Fan controls still seem to work. I tried multiple times on AC power, on battery. Also tried removing the battery. Please advise...

 

Help, please....

 

unplug and remove battery and let discharge for a few minutes. Then try reflashing your bios.

 

How can I flash the BIOS if I see nothing on the screen ? I don't even see the initial Sager logo that appears at startup.

 

If possible try taking out 1 thing at a time and see if you make it to boot like removing CD, HDD, RAM stick etc

 

I'll try that....

 

you can flash blindly. just have to know the key sequence. but i would go with rambo's advice first.

 

Sounds like my current problem with the same laptop. If your vidcard is from nvidia chances are it had kicked the bucket from heat cycles. I sent mine in to sager and they say my 9800m gt will cost $600 to replace. My laptop is 1.5 years old.

 

All these 5793 video card failures are freaking me out.

 

Be smart then and back off the memory overclock. A lot of people that overclocked these cards also overvolted them and overclocked the memory. Those just aren't things you should do with a laptop gpu.

 

Actually, the best advice I've found is never turn off the notebook. This is a problem with heat cycles and die bump cracking because the bump expands and cools at a different rate than the PCB and the underfill (which is why "baking" might fix it), so reducing the amount of heat cycles, or temperature variation will save the card more than anything. The notebook fans will far outlive the chips, and are cheaper to replace anyways. I have run many long tests and I only get a 2-3c difference from running stock vs oc with max fan speed.

 

Um not sure how you came up with the not turning the laptop off idea, because theres a 30-40c temp difference from idle and gaming and that alone would be a heat cycle. You also are not able to monitor the temperature of the memory and I doubt you took the heatsink off to check what the max clocks are for your memory, but that doesn't really matter since your overclocked past the max for either of the memory chips that can come for your gpu. I look forward to your dead gpu post.

 

fo'sho, I will join the masses soon enough. Oh, and idle is 48c @(383/767/301) game load around 70-72c @(600/1500/950), so about a 24c difference, better than letting it cool all the way to 23c by turning it off and on several times a day. I am going to ease back on the oc though, which will keep me at a 20c or less heating/cooling cycle.

 

seems kind of high to me for a idle temp, mine was always closer to 40-41c. I guess its started already

 

Nope, its always idled there. What happened to your old 5793? Did it die? lol.

edit: took oc down to 540/1350/799, good?

 

>.> no neither one of them died, I sold them to people here on the forums. Overclocking the gpu and shaders is fine its the memory overclock that people should leave alone.

 

Could you advise me then, on the key sequence ?
Also, my internal hard disk takes boot priority over the optical drive.

Same here... Around 1.5 years old.

I've never overclocked...

 

You can OC the memories as well, but you need to keep in mind the manufacturer's specified frequencies:

Well, I use a bootable usb drive. If you can't get to the bios screen, I guess you could take out the HDD and it should boot straight to the usb drive, should work the same with the optical drive too. I haven't flashed the mobo bios in a while, so I forget the key sequence, but it seems this is really not your problem anyways, but I can find out the key sequence if you like.

 

Ok Just an update... I tried connecting to an external display monitor... And still no video output!! Nor any audio... If I connect external hard drives, they power on, so motherboard should be fine, right ?

 

Isn't this happening to a lot of guys who purchased this model with the 8800M GTX ? I would just like an official word from Sager, Clevo or the resellers... What is going on ? Is this a failed model or what ?

 

It's not the model, it's the card. NVidia had a production issue with a lot of their 8 series cards, regarding weak solder that would micro-fracture over time. Many, many other notebook models (not just the NP5793) with this graphics card also had this problem.

 

I think we need to make a sticky regarding the 8800M GTX and its failure so that people know exactly what's happening.

I don't have a 8800M, otherwise I would make it. But someone who does should make such a thread.

 

I agree... And shouldn't we get compensated for nVidia's failed and yet RTM product ?

 

nah. is just the lead free welding material. when solder is made without lead, the stability in high thermal stress would crack the solder joints on the gpu core and memory. when you push the gpu to its limits and don´t care about temps, you will have a dead gpu. the solutions for the 8800m gtx that are dying would be reballed the core and memory modules with a welding material with lead. i´m sure that doing that work the cards will last a lot of time.

 

a similar problem just happened to my m570ru, 7950GTX gpu. I would start the laptop and the screen would turn on put no image and so on. Obviously my gpu had died out on me. I baked it in the oven for 10 mins and there ya go my gpu has been running all my same games for the past month just fine. you can look around on the forums or google for some good directions on baking your card. its really easy and worked great for me.

 

Ok but baking the card is just a temporary solution. I just don't get how people are so cool about just paying up for nVidia's screw up!!..

 

Yea this pisses me off too.

I have to run my 8800M GTX at 200mhz memory / 350mhz core (3D) or else it crashes the computer and shows a weird pattern on the screen.

I haven't even overclocked the card, I've taken good care of it; I am sure it's never surpassed 70 degrees at any point. Yet it still breaks after 2 years.

This happened with my previous laptop as well. The 7900GS card of my Inspiron 9400 failed after only 1 year of careful use.

It seems nVidia screws this up time and time again. I bet it's the same with the 280M GTX cards, 380M GTX and eventually the 480M GTX.

I'm never buying a nVidia product again, I'm tired of their crappy products and terrible support system. I'm glad Intel is moving into the performance market of GPU. Eventually I hope the whole GPU goes onto the CPU chip, and we can say good riddance to nVidia and their crappy products.

 

Have had a 7600 go in a previously owned HP and the original 9800GTS 512mb card in my sager below go bad on me, 2 weeks after I bought the notebook, of course covered under warranty, replaced with a 1gb 9800GTS.

That's 2 strikes for Nvidia, one more and ATI forever for me !

 

1 Strike's enough for me... I CAN'T bring myself to trust nVidia anymore, no matter how sad it sounds, it's ATI for me now...
