Troubleshooting Sony Vaio.

post #1 of 6
Thread Starter 
Hey guys need some input here on troubleshooting this laptop that belongs to a fellow co-worker. I told him i would just take a look to see if i can determine the problem.
So far i have chalked it up to a fan or heat problem, or could be a bad hard disc problem. I have not done a lot of laptop troubleshooting in my days of pc building and desktop repairing. So a lot of laptop priorities are new to me.

I first got this laptop, and when i turned it on. It would show the sony logo, then immediately go to a screen that said.... "System did not boot correctly last time" , and give 2 options.
-Start data recovery and proceed to Operating system
-Ignore and boot to operating system
At this point the keyboard is locked up, i cant choose an option and it just sits on this screen.
After noticing this i tried holding f2, f3, f6, delete. Windows key + function keys. All of the sort to try and get to a different screen or bios or bootup screen. Nothing has been successful. I plugged in a USB keyboard seperate to rule out it being a failed keyboard. Still nothing, keyboard is good.
I did manage to get to a post screen, that says nothing but intel and bios, and nothing else. Sits there on that screen and goes no futher.
So im assuming this is the post screen and it will not post.
I tried swapping memory sticks, nothing changed. I removed the hard disc at one point and got to a screen that said OS not found. So i put it back in again and same thing, nothing. So i cant tell if the Drive is bad or not.
I Dismantled dissected the whole entire laptop to try to find a cmos battery to remove, and had 0 luck. I am thinking this is another laptop with a EEPROM chip.
So now i am out of options, aside from the fact i noticed when i turned it on while it was dissected that the cpu fan with heatsink did not turn on.
I figured maybe it only turns on when it starts to get hot. So i dont know.
Will it not post if the fan is bad ?
I am also leaning that the board is bad. If so, nothing i can do.
Anyone have any ideas.

To rule out any nub questions:
Battery is good. Cord is good(checked with multimeter).

Please ask probing questions, i will answer them or check immediately.
Thanks for any help you guys can provide me with.

LOL, sometimes my own intelligence scares me.

I got it up and running.
I removed the processor and cleaned heatsink and reapplied TIM
Cleaned and removed the thermal pad on the chipset and placed ocz freeze on it as well as on the processor.
Booted right up into windows.
However i think the fan is broken on the heatsink.
The high end ultra OCZ paste is helping it run just fine as passive.
Might suggest the owner to have me replace the fan on it though.

Well problem solved....
LOL thanks anyway.

I am reopening this thread because i am still troubleshooting this laptop.
Above is all correct and true.
However....... here is the problem i have been facing for 2 weeks+

In the most simplest of forms i can put it is.

When i replace the cover/shield/chassis

The laptop wont boot.
Or
It will display an Intel logo stating de-compilation or dis-assembly of this product is prohibited.

Remove the cover. It boots up just fine.
I have placed tape all over the board trying to eliminate grounding issues.
I have striped this down to the bare bones to look for issues.
I have removed and tried with different things in place
Different HD different cd drive. Man handled the LCD and close open hinges.
Cut stems off the case that could have been grounding.
I am not so sure it is even grounding out anymore. I dont know what to make of this situation. Has anyone experienced this before or has any logic guess or clue as to what i can try ? or what EXACTLY is this issue at hand.
Its almost like a safe mode or alarm that will prevent me from putting this thing back together once it has been taken apart.
Stupid sony vaio, im so pissed at this laptop now and im about to chunk it.
The owner no longer wants it.

Maybe it's not the CPU that is overheating, as you ruled that out by applying some OCZ thermal paste.

It could be the NB or another part of the motherboard that get's hot with the case on, but stays cool with it off. Has the bottom got any system fans on it other than the one for the CPU cooler?
