Z590motherboard warp D: D: can i repair it?

now that i have taken my processor out and put other ones in, taken my motherboard out a few times etc it seems as though the motherboard of my Sony Z 590 has warped...
it only seems to start up at all when the keyboard is taken off and i am pressing on a certain part of the board as shown in the attached picture.
im feeling like it has to be bent along that line a certain way to work.

i have tried to screw it back together tightly in the middle, but i think it just doesnt position it correctly.
i was thinking i could use some washers to accomplish this, but i dont know where i would find some the right size.
does anyone know if this could just be some connection or ribbon cable? if so, which one? it seemed to work even if most of the peripheral parts were not plugged in.

all of the brown covered connectors are things like the wireless, wan card, and sd card reader, not sure about the ones on the right though, could that have done it?
any help/ideas appreciated.

 

The motherboard is warped?
Are you sure that you are installing it properly?
The times when I could not get a motherboard to fit properly, it turned out that a loose wire was preventing it from fitting properly. Wires such as speaker wire, touchpad wires, etc.

I would check that first. If it turns out the motherboard is bent, just install it as is. If you go to bend the motherboard, chances are you will snap a wire trace in one of the multiple layers of the circuit board. You could use small washers, but I would only use plastic washers. Finding plastic washers is not easy. I suggest going to MSC or McMasterCarr for parts. You can order online, or on the phone. You want to use plastic as it is non conductive. You do not want to use metal washers.

it fits in the case absolutely fine, as far as i can tell.
its just that it only works if i bend it slightly in one way. i mean the computer only starts up at all when i bend it...
my thought is that a wire trace may already have been broken. unless its a wire not on the motherboard but connecting to it i am half missing.

yeah i was not planning on using metal washers. probably rubber since its the fault of the damn case transferring shock directly to the motherboard

 

If it only works when you bend it, the motherboard has already sustained some damage.

Good luck finding the rubber washers.
If it ends up not working, you could try using a heat gun to heat up the creased area of the motherboard. You will need to place the motherboard on a completely level surface to yield good results.

thanks.

the line i made on the picture of my motherboard is just a guess based on how i have bent it to make it work.
if i were to use a heat gun, can you link me to some sort of more comprehensive guide to doing that? like, locating where its most likely broken...
for all i know this could be the cable to the power button :/

 

Would it be possible to insert a piece of hard plastic into the chassis like a piece of plexiglas to support and apply a pressure on the motherboard to keep it working?

When it comes to heatgunning the motherboard, that is a last resort. You just need to setup a surface which supports the motherboard, so that it can lie flat. Then you heat the board up from a distance of 18" or so. The head will reflow the solder on the motherboard, and it will heat up the motherboard enough that it should flatten itself out. Let it cool slowly, and it may work.
However, I would try the washers or a plastic shim before conducting any heat based fixes.

hmm alright
i dunno about a piece of plastic. i feel like i would have to glue it in there for that to work.
ive always thought that the sony carbon fiber chassis should have ribbing or something to make it stronger though...
i think ill just try washers and get back to you if i have to resort to heatgunning
thanks

 

Agreed here... this is really a very last resort... try the washers first and only if doesn't work , use the heatgun...

 

i need some more help.

i opened it up recently, and tried unplugging and replugging various things to get it to start up.
as i unplugged the cable to the ev-do sprint card (or whatever it is, i attached a pic) and the power button LED blinked on once - it was doing that before when i plugged the power it in the first time the casing was open. also when i was trying to bend it slightly, evidently that was not the exact problem.
with the ev-do card unplugged, it turned on reliably. at least a few times. plugged in, nothing. after a few times unplugging and replugging it stopped working entirely...

what is the plug i have in the rectangle?

is there anything i could accomplish with an electrical tester?
does anyone know more about this motherboard on the physical side at all?
any ideas greatly appreciated!!

 

There's a cable runs from it. Can you tell where the cable goes to?

 

it disappears into the left hinge along with the the cable for the screen and stuff...
the power jack is right there. do you think a 4 pin molex plug with a thin little cable could be the power? :/

 

Yes it could be.. or it could be a cable to supply power to inverter board.
But if you have unplugged it and the screen works fine I guess thats not for inverter.

So now even though you unplug the ev-do the system won't start ??

 

yep so im basically back at square one except worse.
i dont know if i ever have started it up without that cable plugged in. i have no way of knowing if the screen would work without it plugged in.

has anyone here ever diagnosed a laptop motherboard problem with a tester?

 

Did you check ebay, you might find a used motherboard for 200.

 

i looked. most are around 300. how would i know if my screen is compatible?
what about buying guaranteed fixed cost repairs? anyone have experience with that?
i dont even know if its the motherboard. it could be a cable. THIS is all i really want to know right now.

 

Can you leave the internal screen disconnected and try booting with just an external screen?

 

i could, i dont know where that would get me... i was wondering how to know if my screen is compatible with a motherboard that i would potentially buy, before buying it.
the current motherboard seems to be shot, at least going by the diagnostic expertise of the forum members who have replied

 

well, i just bought this:
http://cgi.ebay.com/ws/eBayISAPI.dl...9725772&ssPageName=STRK:MEWNX:IT#ht_500wt_979

i kinda think i might come out even...

 

Great price for the stuffs you'll get

 

yeah, the cpu is a p9500. anyone need it?
ive also got an extra p8700 lol

 

the new motherboard works well, despite being the 128mb Vram version usually for the lower resolution screen.
oh and i sold it.
anybody need any Z parts? wonder if i should still try heatgunning my old motherboard or just give it away...

 

no harm done trying... i would go ahead and heat gun it.
