Hello there,
I have a strange problem with my Satellite Pro 4600 . These last 3 days, I have dificulties to start the computer. When I push on the power button, the power light in the front of the computer comes on, I can hear a very small noise but then , nothing more. The hard drive is not doing anything and the computer stays like that, not doing anything. The strange thing is that if I try again and again, I am finally able to start it normally and then the hard drive is going well. I was able to save all my data on CDs for few hours without any other problem so I doubt it is a hard drive problem. the battery was not charging anymore these last months and somebody told me that maybe it was due to that but removing it didn't fix the problem.
Anybody has an idea about this?
thanks
sylvie

Hi

Have not had any sucess in finding the component yet(deadend)
(not sure it is a componet at all, it could just be badly burned tracks on mobo)

Have tried several solutions to go around this problem, but no start up yet :-(

Itīs not that difficult to take the Toshiba apart.(just remember to document everything)

1 # Start at the bottom and unscrew all screws(draw a A4 paper of all holes and put screws there)
(the screws on the Wlan cover is a little bit harder, I used a wirecutter)

2 # Then turn it around and open the lcd, take off the cover on the top of the keyboard and you will reaweel
2 screwīs that hold the keyboard down .(the cover where itīs written Toshiba Satellite Pro 4600)

3 # Then unsrew all screws that is under the keyboard.(draw a A4 paper of all holes and put screws there)

4 # Look at the backside where the connectors are (I/O), there is 2 screweīs there .

5 # Take off the flatcabels(2) that are under the keyboard and you are ready to remove the top + Lcd screen.

6 # You should now see where the problem is, it is just beside the power On button close to a "Tokin(cm)" component .

Hope this helps you a little bit :-)
Please report back if you have any sucess in fixing the Toshiba .

Best Regards
Tommy Johansen
Ps : sorry for the bad english .

Is it possible that the burnt tracks you refer too could be a result of an intermittent Power On Button? It's possible that the CBA overheated causing the burnt traces. Can you disassemble the unit, and clean the circuit board with some Contact Cleaner. Of course remove all power before. Then maybe solder some wire leads onto the traces of the Power On Button and after reapplying power (do be careful), short the two wires together, simulating a Power On Button push. lol

Thanks for the link, i have sendt them a mail asking if they have systemboard in stock .
Have recived a mail from another firm that wants 400€ for a used systemboard .(they are not getting that amount of money from me)

About the power button, itīs not thatīs causing the problems(see first post)
I can turn the unit on, but it only gives a green light(on) and a moan .. . . . . . then nothing more.

Do you have any experinces in fixing system boards for laptops Eric ?
Can I send you some pictures of the problem ?

I too have a dead Toshiba Satellite Pro 4600. Symptoms are the same as described above. The toshiba shop told me it's the power supply, which is integrated into the motherboard, so I need a new motherboard. they wanted about a grand to do it, which is more than the thing is worth. blahhh.

Should I try taking the thing apart to check if its something I can replace myself (with no fancy tools... just screwdrivers, pliers, hammers, etc.) should I just sell it for parts on ebay?

Thanks for any suggestions...

i got a 4600 in yesterday with this

Power button and slight click from the floppy drive, have tried the normal tricks

Booting with no HHD, Floppy, CD Rom taking all mods off like extra ram,
Cant be the power plug as the owner runs it on a docking station

This is much out of warranty so will leave him with the spare for now and take the laptop apart and have a look, thought it was the PCB, so is that part of the mobo ? ive had other laptops with warranty replaced PCB's (power supply board )

Same problem. Narrowed down to either the floppy drive or the floppy data cable. The noise you hear when you turn it on is the floppy drive. I am planning on replacing them both. Will post more info on this later.

Hi All
I had a similar issue with my Satillite pro 4600. On mine the light would come on but it would not have any noise to it at all. There is away to test the Power supply to see if it is working or not though.

!!! DO AT YOUR OWN RISK !!!!

Take the Battery out
Hold the power button on till it boots up ( the front light will be orange instead of green )

The screen that comes up will not be the toshiba splash screen but but a Black screen that I think says
ECSK error please insert disk to continue. ( or something like that )
Your fan will come on full speed as well so If it does boot up to this the PS is working.
Hold the power button down again till it turns off.

How I fixed mine is I had an old power cord with the transformer from another Toshiba laptop that was the same voltage sitting around so out of desperation I plugged it in to my Laptop and It booted right up.( this is after having it sit for a month as a paperweight ) I also downloaded a fan program so I could manually turn on my cooling fan because it was not coming on when it should. After using it for a few months it seemed to fix itself and has been working great ever since even without the fan program I also updated my Intel chipset drivers from intel. This seem to speed it up alot. Except for gaming the graphics card is not supported in most games :( .

I also took it into 2 differn't shops and they also told me I needed a new mobo.
Hope this helps
Ellis

Ellis, I'm a little confused. Are you saying that by simply using a new power adapter you got it working? I did that power test on my laptop and it did start up and it got to a white screen with no text and the fan came on full speed. I would assume the power supply is working. I was also able to switch it to the battery and it ran the same way, so I assume the battery is working. I don't see how a new power adapter will fix the problem. Thanks!

Hi Peter

I'm not to sure why it worked either. Not unless there is some kind of voltage varience between the 2 adapters. All that I am aware of is now I have a working laptop instead of a dead one just by switching the adapters.

I forgot to metion though I had unplugged the CMOS battery and left it for a day during this process. I doubt that had anything to do with it because it didn't work after I plugged it back in. Only when I changed the adapters it started working again.

I had it 2 differn't Toshiba authorized dealers and they both said the MOBO was no good.

Go figure :)

Ellis

Ellis, thanks for clearing that up. I guess I'll just have to play around with it some more. BTW, had you had any trouble with the floppy drive before this happend? Like maybe the drive coming on for no reason or not reading a disk? Thanks!

Does anyone know if a disabled floppy drive could cause a no boot situation? I have a feeling it's the floppy drive or cable. I know in a desktop you would get a drive failure message of some sort but laptops are different.

Did anyone ever come up with a solution to this? Let me describe my issue, it sounds similar to yours.


The light that indicates the power supply is plugged in is on.
When a battery is installed, the charge light comes on
I can turn the machine on (the green light says so) and I hear a very faint click.
The screen remains blank.
If I random keys, a white message comes up saying "Ready for EC/KBC update, place the diskette in the drive"
Or if I press the F12 key, it tells me "Ready for BIOS update, please insert disk....". and the drive light comes on and stays on.
I did make a BIOS update disk from the Toshiba website.
When I put the disk in, nothing happens. It does not read the disk.

I've pulled the memory, wireless antenna, hard drive etc to try to stumble across a fix. I've even changed to a different power brick as someone else suggested. No luck. This laptop has been like this for more than 6 months. In the meantime, I got a new one. I'd sure like to get this one fixed and have it available for installing Linux.

Any ideas?

Try moving the floppy drive around while booting up. I have been able to get it to boot up that way in the past. Now it's just dead. I think the floppy drive died and the system is designed to fail when a device dies.
