Asus C90s completly dead

Hi, I had my asus c90s now for approximately 4/5 months. Not sure, but it was working wonderful until today. It completely will not start up. I had no previous problems at all. It doesn't have any hardware/software problems. I left it on over night and was downloading a movie. No known viruses on movie. Besides that it was plugged into an outlet. It wont start from plug in or not plug in position. Any known issues here? The power button usually always had a blinking blue light when powered, now it just seems completely dead. Any things or ways I should start trouble shooting to check for blown anything?

-Tried hold on button for extended periods multiple times does nothing. Tried with battery in and out, plugged in and out.


Need help and do not know where to begin.

Thanks

 

Unplug the notebook, pull out the battery and turn the notebook upside down, there is a bios reset button. You'll need something long to push it down, hold it for about 30 seconds. Plug it in and try turning it on. If that doesn't work its time to call your best friends who sold you your notebook or your new BFF at Asus to trouble shot or set up an RMA.

 

Call Asus. If you're lucky you'll end up talking to someone who knows this model.

And if you gotta send it to Asus, be sure to not let any components in (CPU, HDD RAM....).

 

Okay this weird. I tried a few hours to get laptop to turn on this afternoon. Then I packed up my laptop to take apart later at friend house. I left my laptop in the bag in my car while it was snowing so it was freezing cold. Then i get to friends house plugged up everything and was going to reset bios to try that. And before I did I noticed when I plugged in the brick and into computer the battery recharge light turned on and poof laptop worked.

Maybe the extreme cold restored computer?

 

maybe power button is loose or something. Did the power button ever turned blue when you tried to turn it on when you thought it was dead?

 

there was no lights from power button nor power recharge button when I thought i twas dead.

 

Thats really weird, I'd still call Asus about that.

 

The cold isnt going to fix a computer, but they tend to run better in the cold just because heat is always an issue for a computer. Sounds like you may have a gremlin in there somewhere tho, it could come back or be gone so just pay close attention to what happens from here on out.

 

That sounds familiar. When I do overclock testing with my gpu, if I go too far the laptop will cut off. I pull the power cord and wait a while then plug it in. Depending on how long I wait it may or may not come on. Heres the important part: When I test gpu overclock and it gets artifacts but DOESNT cut off, I pull the power cord to kill the power asap. When I do it that way I have to plug it in, try the power, try it again after a while, unplug it and wait a while, then plug it back in and try the power button twice. Its almost like a built in protection on the motherboard. Some sort of abnormal shutdown protection. Its extremely consistent too. Ive had 2 C90s'. One I had to rma but it did the same thing.

Also, it works the same way if you use the battery instead of the power adapter. I have the 90W power brick and motherboard F03.

 

Yeah been running same as before prior to complete shut down, and I used it pretty hardcore prior to shut down. I just relieved and dumbfounded by the fact it fixed itself. I was going with idea I fried my mother board, but no known issues occurring right now. I think I blew my fans though now that I am checking it. They do not seem to be coming on at this very time.

I may have to actually contact Asus tomorrow to replace.

 

I think a similar effect with waiting for a while is:

1. Unplug, take out battery.
2. Press power button for5 or so times, keep pressed for 10-20 seconds each. That will drain any capacitors on the motherboard.
3. Put battery in, try to boot.

 

Maybe there is a loose connection in the power supply and moving it in the car shook it back into place? Either way I would still try and contact ASUS and see if anyone else has had a problem similar to that.
