Everyone who has had this problem should go to this site and sign the petition to Sony.

I have tried many ways and times to get Sony to respond to this issue and they refuse to acknowledge emails or phone calls.

Hi all, I have a similar problem but not exactly the same. My friends Sony Vaio was causing errors all the time and he asked me to have a look at it. After a number of checks it was diagnosed as a faulty hard drive by IBM drive diagnostics. He bought another hard drive and asked me to install it.

I took off the top slide panel (PCG-FX805), removed the keyboard and replaced the hard drive. I put everything back together and powered on to find a black screen. I recharged the battery which flashed an amber light while charging. Only once powering on I heard 1 beep then 3 beeps then 3 beeps then 1 beep, the rest of the time no noise just the green power light, orange battery light and the fan is spinning.

Everything connection wise looks OK and I have tried a single memory module in each slot with the same result.

Any ideas what could have gone wrong or do you think it's the same problem people on this forum have had?

A memory chip may possibly be bad. There are no problems with the RAM slots on that series. Also, you may have a faulty video chip or north bridge chip (chip lifting off the board)

Also, given the history of that model, the AMD mobile Athlon may be faulty as well.. One of these items are more than likely the problem. Unfortunately, the 25watt CPUs are very hard to find and the video chip and the north bridge chip are both soldered to the motherboard.

I posted back on page 65 RE: vaio PCG_GRS700p with a bad mem slot. Well my system's still kicking but if i don't press down on the mem slot door underneath during boot, I'll be short-changed 265 megs for that session. It's a habbit now, for me to just grab the door when I turn it on. I just signed the Sony patition. Hope something comes out of it. Good luck all

Thanks for that Joe, not the news I was hoping for but these things happen. I haven't got any other memory to test it so it looks like it will have to go for repair or to the great scrapyard in the sky. I'll advise him not to buy Sony again.

Hi Dave,

Just avoid placing any objects between the memory door and the RAM chips in order to keep it booting. We've been seeing quite a bit of damage to both the motherboard and the RAM chips themselves after prolonged pressure is applied.

These are sensitive electronics assemblies and pressure to the RAM connectors was offered as a suggestion to temporarily obtain data from the drive and or used as a test to identify the problem. It is by no means a way to continuously operate the laptop.

Dave, from what you've described by temporarily and slightly applying pressure to the bottom isn't nearly as bad as wedging an object under the memory cover.

>> POST Beeps
If your machine beeps when you power it on, the CPU can't be faulty, since the beeps are produced by a program in the BIOS. So you can eliminate that possibility.

IIRC, 1-3-3 beeps means the video subsystem isn't responding correctly. The chip has probably developed an intermittent solder connection to the mobo.

My wife purchased a Vaio PCG-7D2L (that's what it has on the label... on the bottom of the screen it says VGN-FS742/W), which seemed to work fine for a week. Now, it freezes during POST.
On power up, the Vaio/Intel/Phoenix splash screen comes up with accompanying sound. If the machine is left alone, it will freeze there.
If I press <Esc>, I get the POST messages:

Phoenix NoteBIOS 4.0 Release 6.0
Copyright 1985-2003 Phoenix Technologies Ltd
All Rights reserved

CPU = Intel(R) Pentium(R) M processor 1.73GHz
256M System RAM Passed
2048K Cache SRAM Passed
System BIOS shadowed
Video BIOS shadowed
Fixed Disk 0: TOSHIBA MK8025GAS

Press <F2> to enter SETUP

.. and freeze ..
It will respond to Ctrl-Alt-Delete, and if I press F2, it's exactly the same, except the message at the bottom is:

Entering SETUP ...

The keyboard lights do exactly as expected on bootup... flashing on, then turning off. The Power/Battery/HDD lights all turn on, with the HDD light turning off after a couple of seconds.

No motherboard beeps.

The machine comes with 512Mb on 2 x 256Mb units, yet the POST is reporting only 256Mb. A clue, methinks.

I swapped the memory modules. Exactly the same report. Seems the memory itself is fine?

So I removed the memory module from the slot nearest the front of the machine. Exactly the same.
I swapped the memory modules again (still leaving the front slot empty). Exactly the same.

Now, lastly I put a memory module in the front slot only. This time it's different... NOTHING... lights on, but NADA. No splash, no POST, no noise...
Ok, and the other module in the same slot. Same again... NOTHING

Looks like the front slot is where the problem lies.

My wife has just got off from a "live chat" with a Sony representative, and the recommendation is to bring it in, under warranty.

Not impressed by the Quality Control. Any recommendations for any further tests and/or solutions I could implement in the meantime ?

I have a GX570 that has worked flawlessly for the past 4 years and I've been very happy with. Recently while on a trip I too started getting erratic behavior, sudden shut downs and the inablity to start, or get into or past BIOS.

After returning home I found this thread, thank you for it. The shimming of the #2 RAM has allowed me to get a funtioning lap top back and I was able to verify that both 256MB RAM chips are fine; and that with out the shim only the first RAM socket is working.

I contacted Sony a few minutes ago asking if they were aware of the cold solder joint issue and problems with memory socket #2 on several models as noted in this thread. The rep denied any knowledge, so I gave them a link to this this thread.

PS. What is the latest BIOS version for the GRX570? On the Sony site they list 2.06. On another forum;stop=20 they mention 2.46 along with great information on a CPU upgrade

>> Shimming the SODIMM sockets can ruin the motherboard
Don't do it. Get it fixed. If you don't, you could turn a repairable machine into a doorstop.


(By the way, it's not a cold solder joint issue. The heat of the processor and memory UNsolders the connections.)

I own another sony vaio model PCG FR415S and have similar problems. First my DVD-RW drive failed to burn DVD than CD than failed to read DVD and know it is completely defunct. Shortly after the problems you describe on this forum started all of the sudden. Now it takes several retries to boot it properly. My symptoms include: all leds on, hdd and fan spinning like crazy - laptop dead or blank screen - laptop dead or operating system starts and hangs while loading. I have dual boot machine windows xp pro and linux fedora fc5 and the behaviour is just the same. But once it boots up properly it works like dandy until next reboot. So I guess the best way is simply to let it run 24/7 like a server ;). Sony support sucks. This was first and last time I ever bought anything from them! Interesting is that these problems started roughly 2 years after I had bought it. I am not paranoid but having read many posts on this forum I slowly start to believe that there is some malicious counter that fires those problems right after your warranty is dead.

Nevertheless I have this problem for a while already and managed to collect some clues that may be helpful. When I start linux it gives some messages before it hangs on those occasions when it fails to boot. The messages are something like:

CPU 0: Machine Check Exception: 0000000000000004 right before it halts and sometimes while it loads the kernel i disables interrupts 9, 10, 11 in any combination. On my laptop 9 - acpi, 10 - sound card, 11 - lan card.
Sometimes when I try to enter bios it displays: Parity Check 2. But of course sometimes it works without any problem... arghhhh.

So this can be just anything from faulty SODIMMS, or I/O bus to fried mobo.

Anyway sony does not care! Warranty has expired. And I am left with it alone.

I am going to buy a new laptop but it will NEVER be sony!

I had the same problem of memory failure and I used a folded paper to push the DIMMs down. I tried to place the folded paper on the sockets but it seems that I did not find the right spot so I only get it working again by pushing the actual dimms down. However because of the internal heat the pressure unsoldered the memory chips and damaged
the sockets. After a while my laptop became very sensitive to the smallest shocks freezing all the time until it stopped working completely.

Because the shipping paperwork and cost are too high (I live in Romania :) ) I had to find a local solution. So I found an excellent engineer that was able to restore my memory dimms but the sockets even re-soldered pin by pin were no longer making contact to the memory dimm. So I needed new sockets :)

This is where my hunting for sockets began:
- I searched the internet but I always found laptop memory dimms not memory sockets
- I tried to find a broken laptop wit compatible memory sockets to reuse them (this was a long shot anyway because it needed two risky operations)
- I posted here a help message that was only replayed by Tom Pappas (I like this guy :) )

Three weeks ago I received two new 200pins sockets from Tom and I went again to my engineer to replace them. He burned out (using hot air) and unsoldered the old sockets and installed the new ones - the whole operation took about 3 hours and a half. At the end I connected only the necessary parts to the motherboard and I was able to boot my Debian Linux OS with all 512Mb ram usable: oh, great joy :). The only issue after that is that some of contact stripes are very poor quality and got exfoliated and the one that is connecting the jog-dial and the power,hdd and battery leds got completely unusable.

I hope that finding such a connecting stripe will not be such a trouble and for the last two weeks my laptop is working well but I didn't place the memory cover back on to let it breathe and I am working on a cooling pad.

I am sure that people reading this post will not ask if it was worth it but anyhow I was not prepared to let my laptop die and I indeed was ready to buy another motherboard to keep it going. Although Sony is no longer a dream brand for me I still like the Vaios for they do work smooth (when they do work) and for sure they do look good. Thanks Tom, and thanks go to my friends who helped me and showed me it is possible.

My 2yr old Sony PCG GRT996VP gave up on me last week and now won't turn on at lights no HD sounds zilch zippo nil it is now destined to be a very expensive doorstop unless someone here can advise me on what options I have.
I used to get the odd SODIMM error message and the cpu needed restarting etc, remedied by removing and refitting the ram once. Recently it kept shutting down until I realised that the DC socket was a bit ropey and the AC connector had to be wiggled around a bit inside it before it would start charging the internal batteries again. Finally the central plastic piece in the centre of the dc jack broke in half but I could still power up ok. At this stage I noticed that the underneath of the laptop was getting VERY hot on the left and right hand sides which made it very uncomfortable to sit with for any longer than 20mins. It got so hot that the Connector from the AC supply was too hot to touch recently and melted part of its sleeve!!! I put this down to the dodgy connection of the broken DC socket and bought a new SOny power supply, but the DC socket being broken was worrying me so I resolved to fix it asap....unfortunately the day after I ordered a new wired DC jack the laptop shut down and has never restarted!! I have since got the new DC jack and fitted it but the laptop remains dead. Does anyone have any ideas on what it could be? Its a nightmare of a machine to get into and I don't relish the thought of it again. Could it be that the motherboard is fried? If so how much are they and where can they be obtained? Its really annoying as the bloody laptop is only 2years old (obviously out of warranty) but was working fine bar the odd glitch mentioned above.

I have had past dealings with SOny Europe before with my desktop which they took away to repair under warranty but returned the machine 2mths later unfixed, sent off again and returned the machine 2mths later again unfixed, eventually they lost it (on purpose I think)and replaced it with a 'reconditioned' machine albeit with a higher spec after several crappy offers of a lower spec machine...You really have to fight them tooth and nail to get anywhere and yes I know how stupid I was to buy another Sony after that experience.....

Any ideas please? I live in the UK.

>> Sounds like the DC jack isn't making contact with the mobo
The failure mode we've seen dozens of times is that the center pin of the power jack breaks the circuit formed by the plated-through hole in the mother board.

So even though that pin is soldered firmly to the PC trace on the BOTTOM of the board, there is no continuity to the trace on the TOP of the board, which is the one that actually carries the voltage to the electronics.

The fix: clean the solder mask off the top of the board so it's shiny copper, and make sure that the center pin connector is soldered firmly to it.

No Tom that won't work as it is a wired DC connector (ie the socket isn't soldered to the Mobo directly like some Sonys...

>> Re: Sony Vaio laptop wont boot?

Can it be that the laptop shutdown due to the battery going dead? At the same time or slightly before, the DC connector / jack taking out the surface mount fuse (on bottom of the board near the white connector for remote DC Jack) before the battery went dead since from your description as it was very hot in the area to a melting point.

First thing I would try is to dis-charge the whole system, remove all power and remove the CMOS battery then hold the rest button for 5 seconds or so, then re-apply power and see what happens.

Also, make sure the flat flex ribbon cable for the power button is not damaged or has damaged leads..

I recently bought 3 Sony Vaio PCG-GRX560s off eBay and was aware of the memory problem. I believe I have fixed that issue by using a 512MB RAM chip in slot 1 only.

The problem I am having however is with the boot issue. One of the Vaio's eventually boots (with power cable) BUT ONLY AFTER I hit the power up button 20+ times!! I know I'm not the only one who's experienced this. I've tried searching through the posts here (and I'm very happy to know there is help like this site available) ... but can anyone actually tell me what they think the issue is here? Is it a bad power cord/wall wart, dirty circuits, or just my bad luck?!

If it CAN be fixed, any suggestions on who would be the most confident in fixing it?
