I have a VGN-SZ650 and it wont boot..LEDs are on, CD and fan spin but the screen is just blank. My vaio originally runs vista business but it crashed, so I formatted and installed the Dell home premium version. and this happened after I updated the original driver (business version) for the intel chipset currently running in Home Premium.

I've tried to reseat/swithc the RAM but it didn't work. it seems to me that the motherboard and harddrive not working. I dont't have warranty for this one so I wanna give it a try before I would have send it to sony for repair. anyone knows if the wrong drivers could cause the laptop to not booting?? I think i did smell something bad when I manually turned on and off the power button and I'm just hoping the motherboard didn't get burned. Please help!!!

Hi we have a sony PCG-661P which will not boot up.We've sent it to Sony who've told us that the electricity supply to the laptop has been unstable for some time therefore it's not repairable.
I've check Joe Kabalan's list of models which can be fixed with the faulty RAM port but our model isnt listed.
Can anyone help with advice on what to do?
BTW, we live in Shanghai so can't really ship it to Joe for repair. HELP!

Hi My PCG-9l1M ( about 5 years old had all the same conditions asmentioned on this board. There were no lichts or any thing when pluggd in.
I swapped power supplies, still nothing.
I swapped the memory, and even inserted the very old original 156. still notning.
Then wrapped in "cling film" food wrap into the freezer for 30 mins, and still nothing.
I then went to PC world to chech what VAIO to get nect and see if they could svae the most recent data from the hard drive (I back up onto an external hard drive every couple of weeks, ( after this scare I must do it every week)
Anyhow, there tech guys told me to remove the battery, then with out being plugged in to the mains, hold the on button down for 30 seconds, then plug into the mains and turn on.
And it works now.

I hope this helps others.

-power adapter good.

1.i discconect everything from motherboard(to see if anything causing a problem):hdd,cd-rom,audio card,modem etc,restet for 30s,disconect cmos battery,...nothing.still the same as above.Plug in external monitor on vga-out -nothing.
2.i apply some pressure around memory and memory socket,swap memory( i have only one 512mb stick) still nothing
3.i apply some pressure(lightly) arround video chip ,even take off heat sink ,then apply some pressure around all motherboard- still nothing
4.i send to local service ,guy could not fix it.he even try to resolder video chip(as far as i'm concern) still nothing.(same as at the begining)

What could it be ??? the only thing i haven't try is to put diffrent ram,but i dont think this is an issue.

OK it's my turn,pcg560,normal symptons,green light,fans startand then nothing.Tried the memory tric still not sure,I have two 256 s.But I have noticed that if I turn it on and leave it for about 5 min then reboot everything will work fine.Also the backlight went out at the sametime.But then it would boot everytime on an external monitor.Backlight has since been replaced. So whats up and is it worth fixing?.Thanks

Wow, huge thread, and I thought I'd find a solution but didn't.

I have a Sony VAIO VGN-FS550 that randomly decided not to boot. I have upgraded the memory from 512mb to 1gb.

All my LEDS light up, fans whir, hard drive spins, but just a black screen. No VAIO logo or anything. I have tried the following:

- Taking out the upgraded memory, replacing with original.
- Taking out slot 1 memory, leaving slot 2 with 512mb and 256mb sticks.
- Taking out slot 2 memory, leaving slot 1 with 512mb and 256mb sticks.

- Taking laptop apart. I removed the hard drive, optical drive, and basically anything else that can come off the bottom of the board. Strangely, I couldn't figure out how to remove the motherboard from the case. I am sure I had all the screws out, and wasn't sure if there were any tight wires I was going to tear out if I just pulled.

We did have a problem a while ago where the laptop would not boot at all, no lights, no whir, nothing. I took the laptop apart, put it back together, and it was fine. This time, no such luck. I am at a loss for what to do, especially because busted things typically get fixed.

If there is no feasable solution, I may just buy a new laptop as I'd rather put money towards that than sending a laptop across the border (no offense Joe, you seem to be a great help to the people here).

Thanks in advance!

>> Re: Sony Vaio laptop wont boot? those laptops seems to be more complicted than BOEING!
Hey Matthew
Yes unfortunately no one come across with good guide step by step with picture and diagram how to fix that,so we could give direction to our local service (my local service in Poland(europe) cant help)how to to that,rather that sendig laptop aboard which isn;t cheap either,
Buying second hand motherboard doesn't give you 100% chance that you will purchase working motherboars,just as i bought "working"one for $150 on eaby .BOLLOCKS..waist of money,seller didn't reply.
All i thinking about for now is just taking laptop apart and selling those parts,Waist ot time and money trying to find solution,sending to local service (they cant fix as it's so complcicated just like fixing a Boeing or something),buying faulty parts..bla bla bla

Matthew you can try fallowing if you havent try it yet:
-try your laptop on external monitor ,vga-out in your laptop
-apply some pressure (just to test )around video chip(you might have faulty video),memory stick and socket,around motherboard as you might have a microcrack,broken circuit!!
-try to swap processor with a known good one
-hold down reset button for 30s
-try testing without laptop battery
-unplug bios battery for a while
-check all of flex cable as they break easly
-some people try to cool down or heat up laptop (even in fridge) metal-temperatur effect.
-be aware of static electricity

thats all i can think of ,but i'm not a specialist ,i'm guy just like you trying to find solution

but to be honest i fed up,

Good luck to everybody

Hi, I had this problem tackled on my friends Sony Vaio PCG-GRV616S. One of the two 256 Infineon memory modules removed (the one most near the user-side of the laptop) and it booted. Seemed that one module died on his Vaio. The first one can be dead too, then switch the still alive memory module towards the backside of the laptop (I think that is slot 1). HDD light didn't flash at all. Battery light flashed. Keyboard-lights didn't work (Caps lock and Num lock). I thought the whole machine was ready for the scrapheap.
Indeed the Vaio seemed to be dead... didn't boot. Not a very nice BIOS section. You can't let the memory be counted and checked before booting. Perhaps there is a new BIOS update for that. I'll check. Now I'm looking for a repair of one of the hinges. The head of the screw broke of. I think this Sony Vaio was too expensive and not much value for money.

Well, untill today I didnt realize the problem. I never had a problem with my GRX550 until last night when i took it out of storage and re-installed everything for a friend i was going to give it to. After installing, It wouldnt boot, just black screen. After about 20 tries, it would start to boot then hang. So on and so on.. Now when i plug it in, the lights above the power key lights for a split second. When i turn it on, only thing that happens is the Green light stays steady as well as both Battery lights stay on (orange) and steady. This is without any battery in it. Tried the memory - didnt help.

Anyone know if this is repairable? I did not see anyone else have the same issue with all three lights staying on. Thanks

Try to boot after removing one memory module. If it doesnt work then try removing the other one.

>> Re: Sony Vaio laptop wont boot?
In addition to my previous message solving the problem of not booting, this was not due to a corrupted memory module but to a faulty memory bank on de laptop itself. One of the existing modules was working correct (machine booted) in slot 1, but when its place was taken by a larger memory module it moved to bank 2. Then the machine wouldn't boot anymore. Only option is to leave bank 2 empty. This problem persisted with both 256 MB modules in bank 2.
Don't now what you can do when bank 1 was broken, and you would leave it empty and put all memory in bank 2. Usually you should use bank 1 before you can use bank 2.
For good understanding: bank 1 is the rear one, bank 2 is the front one. Manual leaves the user ignorant on this. It points towards the rear module when adding a module. So it seems that the front bank would be bank 1. That is possible only when no order in filling banks would be obligatory.
Somewhere else on this site you can read about broken soldering on the memory bank connection to the motherboard. Soldering through is difficult and perhaps the only solution. Changing the motherboard is the other (almost impossible) solution.

vaio would only boot with 1 mem stick installed. after reading all these forums and trying several different things, i decided to look at the mem bank 2 under a magnifier
(a quality "loop" or "linen" tester) i found that one and only "ONE" of the prongs were
bent down and stuck. it was a real pain in the butt and was like performing microscopic
surgery, however i got it pulled back up and got my MEMORY BANK 2 back. the computer is working good again. HOPE THIS HELPS

I have a Sony VGN-FS775PH, and it won't boot up. I dont' know what happened, it was working fine, I could shut it down fine, but then after a day it just won't start up!
LEDs don't blink, nothing from the fans...

However, if I disconnect the battery and the power adapter for about 10 minutes, I can hear 4 faint clicking sounds coming from near the power switch when I try to start it up... The clicking only happens if I plug in the battery AND I disconnect all power sources for about 10 minutes

Am I SOL? :(

Sony Vaio VGN-T350P. 2 years old.

I've had issues with the sound card since 3 months after I bought the thing -- whenever I would place pressure on the wristpad, the sound would cut out or the "MUTE" light would turn off.

Sony has repaired it thrice and it is now out of warranty.

Additionally, now I'm having problems booting up my laptop. I'll press the power button, only to have a black backlit screen pop up, and nothing else.

Sometimes, if I put it in the corner and don't touch it for a few days, it will start working again.

I am currently having a problem with my Sony VAIO VGN S150

But I'll tell a short story first. I first bought this around summer 2004. Within a year, I was experiencing the problem many of us described. Laptop powers up, but black screen. Requires multiple hardboots to get the screen back. Sometimes if you move the laptop around the screen would disappear and it would be time to do multiple hardboots again. I took this laptop to SONY in San Diego and they replaced my motherboard for me.

Ever since that everything is nice and dandy.. Until last night.

My laptop was getting really hot constantly, I figured it needed a good cleaning so I tried to open up the laptop... I started it without googling on how to do that first, big mistake. I tried to forcefully lift the speaker part while the keyboard was not taken out first. Either way, I did not physically break anything, but after I screwed everything back, my VAIO now will not boot up.

The problem I am getting is, I press the power button and the power (green) and the battery (orange) at the front right panel (around the area of Wireless on/off switch) would stay on for about 1 second, then turns off.

My question here is........ is this an atypical motherboard problem? I hope I did not semi-forceably break a perfectly good motherboard.

Today I figured out how to properly dissemble the laptop and the grill next to the fan was completely clogged (around where your enter key is). I do not see any visible damage to the motherboard from me trying to pry open the laptop incorrectly, and I do not think I directly touched anything inside when I was prying it open. i only messed around with the edges and upper area of inside (so around keyboard area instead of bottom going toward the motherboard itself)

any suggestions would be appreciated.

edit: if i plug in the power cord from charger, I DO NOT see the orange battery light blinking like it normally would.

I have a VAIO VGN-FS570 that seems to get no power at all. I checked the power supply and get the right voltage. I checked the lines from the power connector to the motherboard and they checked good. I get no lights, fan spin, or anything else. I read that Joe said that there is no memory issue with the FS series but I tried anyway. No luck. Is there anything that I can do to try to fix this.

I am a certified microminiature repair technician and have the equipment to do the repair. The problem is I don't know what needs repaired. Any help is appreciated.

Hi Josh,

The FS series boards usually develop a short condition somewhere on the motherboard. The exact location of the short varies on a board to board basis.

I seemed to figure out my problem. I started tracing the power levels from the DC jack and noticed that I was having a hard time getting readings. I noticed the end of the power cord that plugs into the dc jack was missing some plastic coating on the end. It was as if the cord got too hot and melted the plastic that was on the end. I bent the negative tab on the inside of the DC jack out a little more and slightly bent the positive post on the power cord and plugged it in. No luck so I twisted the power cord in the dc jack and suddenly I had power. I have to keep the plug in a certain position or it jumps to battery power and doesn't work. So I ordered the DC jack and a new power cord. Hopefully this helps with other people as well.

Thanks for the reply Joe... I'll let you know if it fails again.
