Anyone help is appreciated

 

Laptop: toshiba satellite l355d-s7829 model psle8u-023016

 

I bring it back and forth to my girlfriends..  I am coming here for last resort in hopes someone can help me or lead me in the right direction to getting this fixed..

 

 

- When I push the power button, the fan and power lights come on, but screen is black, no beeps or anything

 

So far I've tried:

 

-Taking battery out, holding power button down for 60 secs, tried powering on without battery in it..

-Making sure ram and hard drive seated properly/ Tried to see if anything would show up without ram or hard drive plugged in

-Hooked to external monitor, still black screen

 

The only thng after researching I haven't tried that a few are saying worked is heating up the motherboard 

 
1. Disassemble the laptop and remove the motherboard from the casing.
 
2. Use a heat gun on high for 15 seconds on the intel chipset and nVidia video chip.
 
3. Wait 10-15 minutes for both to cool down.
 
4. Turn over the motherboard and use the heat gun for 15 seconds to overheat the same areas you just did on the topside.
 
5. Wait 10-15 minutes for both to cool down.
 
6. Reassemble laptop and turn on.
 
 
I wanted to come here first before last resort as this seems risky and taking apart the computer fully..
 
 
 
 
Possible causes that recently happened:
 
- my leg caught onto the power cord while it was plugged in and yanked it a little bit, but it still worked before and after 
 
- When having open files I  wanted to be able to turn the laptop back on and come back to when I put it to sleep or push the power button to shut it down many times it wouldn't turn back on, requiring me to turn it off and back on, losing work so I recently have been just going to switch user and leaving it on..
 
-Many times on the go when leaving I dont shut down properly and just hold the power button down until it turns off
 
 
Please help I really dont want to spend money i dont have right now

well ... I did one last try on the heat gun and popped the ram in.. it booted up.. was able to save the files I wanted to save luckily.. tried to test it out a little bit , turned the cpu off, back on , everything was working good..

now the problem where it wont boot back up again is after I push the power button one quick time, to put it to sleep mode instead of powering off.. once i do that it won't boot back up at all..

any help on what this could be coming from and how to fix?
