Some of my fellow employee's use older Sony Vaio laptops (PCG-505TS, 505TR etc) and we are constantly having to send them to the Sony service center for repair. The most common repair is that they will not power on. The power port on the laptop seems to be failing. The power cords themselves are fine. Each repair costs approx. $300. Is this a common problem for these laptops? My experience suggests yes. And, is there a way for us to purchase a part and replace this part ourselves? If you had to rate Vaio's on a scale of 1-10, what would you give them? Please include you model number if you own a viao laptop.

Thanks for your info.

Because of a fundamentally flawed (or shortsighted) design, the rigid DC power pin inserted into jack on side or back of laptop creates a leverage point to stress the circuit board which receives the power.

Most laptops have this problem, and the root solution is.... (anyone listening).

Hi! I also have this problem with my sony vaio PCG-GRX550 laptop; my power port detects the power cord only after much adjusting of the cord and putting a weight on top of the cord so that the cord somehow makes contact with the power port on the laptop. I really need this fixed, but i have no idea how to; any ideas?

also, I am having problems with my RAM: my motherboard detects only half the 512 RAM; my secondary ram slot does not detect any RAM. Now, I believe the first slot is also starting to become unreliable. Anybody else have a problem similar to this?

Pentium II 400
224 Mixed RAM
16 MB Riva Diamond Viper V550
30GB Toshibal Laptop Hard Drive (-_- my sony vaio pooped out on me)

I'll stop embarrasing me and my computer, thank you.

Hello,
I'm actually in Paris, FRANCE, and i have the same problem.
I sent my laptop (PCG-GRX316MP FR5) to SONY CC, and they sent me the bill, 1910, almost 1900 $ to repair it, because the motherboard is no more powered up by the sector and the processor (P4 M 1.7GHz) has a problem on boot.
can anybody tell me what is the exact name of the motherboard??
They told me MBX-65, but i cannot find the manufacturer.
If i have the type of motherboard, i would be able to find one and fix it.

Thanks a lot.

Bye bye.

Harry

Hello,

The MBX-65 is pretty much the same board used in all the GRX 500 / 600 series.

Sony is the manufacturer of the board. They manufacture their own boards in most models except the FXA / FX210/215

They are extremely hard to find "broken" I could get into the reasons why they are hard to find broken but thats not important here..

I have a PCG-505HS, it also occasionally fails to power up. Strange part is, twice this has happened and the laptop was set aside for several weeks or more and when I came back to it to decide whether to part it out or try and fix it, it booted normally and would work fine for some time (several months to a year).

It just happened to me again yesterday, so I'll wait and see if it resolves itself again.

sure enough, I picked it up this morning and it booted right up. I tried it last week and the only response was that the power light flashed once, then nothing else.
Also the battery charge light is now indicating that it is accepting a charge (laptop is powered down) where as it didn't durring the period of time that it wouldn't boot. (It booted from the battery, but gave me a battery low warning)

I'll never go Sony again. Their customer support is a perfect match for their laptops.... lousey.

Check the voltage of your CMOS battery. if your battery is low it will fail to power up the system. if you leave it sit for a long period of time, it may be having a chance to "recharge" itself..

i was having the same "powering on" problem with my vaio grx550- i had to send it to best buy and they replaced the mother board which took about a month longer than it should have... now i;ve had it back only a couple months and i am getting a message that "operating system cannot be found" when i turn it on. I have heard that this has happened on other vaio's because of a faulty connection between the motherboard and the hd- does anyone know anything about this? I first thought i had a virus but now i wonder if they didn't put my mother board in quite right.

I have a Sony Vaio FX-103 which also has some power up problems, mostly after I've transported it. I will paste the rest of the story about it after this. That tip about the CMOS battery is also something to keep in mind myself, but it doesn't explain why the problem mostly occurs after transport.

Re: Sony Vaio won't start
I have a Sony Vaio FX 103, about three to three and a half years old by now. Always worked flawlessly, until the end of last summer. It was at a summer camp where I was part of the crew when I started running into a peculiar and very frustrating problem. It didn't want to boot anymore. In fact, it even refused to power up. I pressed the power on button, and for about a fraction of a second the normal power lights would light up, my DVD and HD drive would spin up, the fan on my CPU would spin up. And then it all died again. Over and over again. The only way I was able to use it was to let it lie for a while (several hours), and then it powered up again.

After that summer camp the problem didn't return, I started going to college where I made extensive use of my laptop, and it just kept on working. So I didn't really think much of it anymore. Until the problem started to return more and more often. Especially during classes, or tests where I would have a need to use my laptop. So I started doing some research.

I've read about the problem with the seconday memory slot, but since this seems to be a power problem it's not really applicable. I did run some tests with the secondary slot empty, but the problem kept reoccuring. So with a bit of asking around someone mentioned a bit about it having to do with the power circuitry on the motherboard. A relay on the motherboard probaly responsible for making sure the power stays on, and doesn't get cut out after only a moment.

Since the laptop is definately more then three years old I have absolutely no warranty anymore, so any repairs have to be paid for. And before Sony Holland wants to help you through the phone they'd like you to pay 20 euro's. And besides that, if I indeed have to send my laptop off for repairs there is a change that they won't find anything wrong with it. Or that they do find something wrong with it, and that I have to pay about 300 euro's for a replacement motherboard, and quite frankly, I don't think it's worth that.

Now, if anyone else now of another way to fix it, or if someone can help me check if I'm right. I would be very much abliged. At the moment I'm using a laptop of a friend of mine, but since he is quite eager to get it back, I need to come up with a solution, which either comes down to repairing this Sony, or buying a new laptop of the cheapest brand I can find.

I have a Sony Viao Picturebook (PCG-C1VN) that has started having similar problems.

This machine has a Transmeta Curusoe Processor, 128MB built in RAM, a 64MB RAM expansion card and windows XP home installed.

Three months ago, it started freezing and crashing. When I pressed the start button, the led lights would flash and the fan would start, but then that was it. Nothing else happened.

At first I dismissed the problem as just a nuisance from an older computer. If I kept trying, eventually something would click and the thing would start.

Things started to get more strange though in short order. Sometimes it would begin starting ok -- the led lights would flash, the fan would spin, the bios would get loaded an the hard drive would take an initial spin -- but then, the hard drive just sort of paused. I discovered that the pause would come to an end and the computer would continue booting normally if I removed my linksys wireless card from the PCMCIA slot. Sliding the card back in at any point during the rest of the booting would result in a pause again. It was almost as if there wasn't enough power for both the card and the hardrive during boot. Once windows was running, then I could put the card in an use it without trouble.

While trying to figure this mystery out, I then discovered another. The 64MB RAM expansion card was no longer being recognized by either the BIOS or windows. It had been for several months, and then no recognition, no matter how many times I took it out and put it back into the machine.

Then finally, the most vexing appeared. The computer stopped functioning on battery. It recognizes the battery is attached. It is even able to distinguish between the orginal I have a newer double capacity model I bought just a few months ago. But, when I pull the AC plug, it dies. If I try and start the machine without the AC cord, absolutely nothing happens.

I've reinstalled windows xp. Even tried wiping the hard drive and going back to windows ME. Same problems. I've taken the entire thing apart, and can see nothing physically amiss at the macro level. I really quite stumped.

I've read the posting here on Vaio laptops stopping, not starting, and not recognizing memory. Seems similar. Any suggestions?

My Z505HS is suffering from the same problem too! LED flashes once then nothing. But leave it for a few days, it will switch on....CMOS battery looks fine, checked with multimeter and is at the right voltage. Any suggestion?

Have you resolved the problem?

And another instance - PCG-Z600LEK power lights flash, screen flickers, then nothing. Remove battery,
power cord and CMOS battery. Apply power cord, and you can do it once more. If you hold the power
switch for 4 seconds, the power lights are all on , then out (power down). You can repeat this without
removing power. After an indeterminate period with no batteries or power or CMOS battery, the machine will
boot, reporting CMOS checksum error. The CMOS battery seems OK - 3.4v which holds up under 3mA load.

Last time this happened, it started after a day or two and ran for a month with power up/downs. Been working on this failure for nearly a week now, but no luck so far!

Someone, somewhere knows what's wrong. What gets done when this symptom is repaired?

Add one more instance: I have a PCG-GRX570, its almost 2 years old. I had the same problem, it refuses to power up. The HD starts to spin, then nothing. I tried taking out the RAM, battery etc, then it powered a few times. I noticed that when it powered up, if i tried to connect a network cable, or even a USB mouse, the computer froze totally. Now it hasnt powered up in weeks. I took it to a repair place, they said its the motherboard, and that it would cost more than $1500 to fix. They suggested that I sell it for parts.

Any better suggestions? did anybody find a way to fix this problem?

>> Re: Sony Vaio- Will not power on - PCG-NV1270 fixed
Thanks to all who posted solutions here, you guys have given me a clue on how to solve a problem with my PCG-NV170.

For anyone who is/will be possibly struggling in the same problem with NV170, I post about what I have done. If your NV170 does not start up (i.e. not even the SONY logo would come up. If it would, the OS will eventually freezes after a few minutes no matter what you are doing - normal, Safe mode, recovery CD, etc etc).

The solution can be very simple; MEMORY SLOT (after all). Prepare a small + screw driver.

NV170 comes with two memery slots (this someone had said already).
If you open the cover at the bottom of your PC body (the one around the center part. As above you would need a screw driver.), you will see the slots. NV170 (purchased at a Best Buy) came with a 256MB RAM, and thus the other slot is empty.

Try removing the memory card and then insert to the other slot.
Turn on the PC power.
SONY logo should come up and it will proceed, hopefully.

My NV170 has been OK since this method, and everything as far as I can see is working stably. The 256 MB RAM is fully recognized by the machine.

So it seems the failure is somewhat to do with the memory slot (#1) itself.

I am using this NV170 in Japan now and Sony would not support it since purchased in the U.S. (although the same model is on sale as NV55 or something like that). So I asked a guy I found on the web to repair the problem before I had realized this very simple and free (if you have a screw driver) solution, who told me appropximately USD 700 or so to change the mother board.

I am saving that money and see how it goes from here.
Hope this helps someone.

This can be repaired by re-soldering the RAM socket to the board. It is a tedious process, as there are either 144 or 200 pins on each SODIMM slot.

Hi guys, I believe I know what's the problem with Vaio not powering up.
Recently iI try to fix my friend computer GRX5xx and I found out the problem.
Lousy memory sockets used by Sony. There are few lines which read some
info from RAM at power up and if the info is wrong forget it the power come down in
a second or two. I fixed the laptop as I put pressure on the other end of RAM card.
Everiting was fine for an year but the sockets continued to wear out and same
computer is junk now. Anybody to know how to remove and solder some better
socket for the RAM?

I suggest you take a look at
http://www.hardwareanalysis.com/content/topic/5449/

Here you will find people who may be able to fix it up.
Yes I read in the thread that the pressure fix you did would lead the machine to go wrong as seems to be your case. They are talking about re-attaching the socket as the fundamental solution, rather than using pressure-method.
