Why would the DVD be spinning? Take out the disc from the drive. Turn off the laptop completely - press & hold the power button until it shuts down. Unplug the power cord, remove the battery, & then press & hold the power button for about 30 seconds. After doing that, reinstall the battery, replug the power, & see if it will boot.

Incidentally - there isn't s dvd or cd stuck inside the drive is there?

Might be useful to do a manual eject of possible contents - the usual paper clip into the wee small hole where it's located?

riider: When i say dvd is spinning i mean that its made that routine noise when system is checking devices at startup. I did that thing with holding power button for 30/60 sec maybe 5 times already..cos i read that sometimes it works after 3rd attempt.

trvlr: there is no cd in the rom, i did manual eject already :)

At first i thought that mobo is gone but then found about this open lid switch and posts from people that they were able to bring their mashines to live by just cleaning them. But here i think i may have magnetic switch , but im not sure, its just predictions.

You've probably seen this, but just in case....

The first thing to do is try an external monitor on it. That will tell you quite a lot.

If you see a change on the screen when you carefully lower the lid down to nearly closed then a common cause it the connecting cable giving trouble where it hinges. The connectors at either end can work loose too.

Always pop back and let us know the outcome - thanks

painting my room so i wasnt about last nite

rider: sure i have seen this , thanks

Derek: tried an external monitor at an early stages of my investigation :). Also there is no difference at any angle.

Forgot to mention how it all started, laptop was just closed by the lid, and when i open it up it never woke up so thats why i think the sensor/switch is the problem. Its like its still sleeping..

This is a very long shot... (one of Derek's useful tips)

Remove all power, battery included. Press and hold the on/off button for about 30seconds. Then restore power and see if perhaps?

Yes i did and found nothing in it. I even got mobo service manual but cant read it properly. The mobo is 6050A2357401-MB-A02 if u can read electronic i can send u a link?

Cant find anything on this manual but got some news. I posted on the other forum, people there are as good specialists as here. A man think that this is bios problem and need to be reprogrammed. Any ideas?

If by "reprogrammed", you mean correcting or adjusting the BIOS settings, it wouldn't hurt as long as you know what you're doing. If you mean to update or flash the BIOS, it's doubtful it's necessary.

Screen is black so i cant just go into bios so it have to be hardware reprogramming using special tools.

If you never ever see anything on the screen then most likely it is a hardware failure (maybe that switch you mentioned) so messing about with BIOS won't help and if you flash it badly then it will write off the motherboard. You should be able to get into BIOS without any special tools.

Always pop back and let us know the outcome - thanks

long shot - very indeed...

What happens if you attach an external display and activate it via the usual F Key combination?

External monitor doesn't work. Im not talking about flashing Derek. I think the problem is BIOS element. Two choices here: one is using BIOS programmer like CH341A (cheap version)to fix software anomaly or two physically remove faulty BIOS and solder back the good one. Its 8 legs to solder in which is not the end of the world, i soldered many dc jacks in the past.

Have you removed and replaced chips in the past? Generally they're dip soldered or similar and a real PIA to remove - unless one has the correct tools, and a little know how;...?

Have you had a word with Toshiba (?) tech types at all; if only to discover "where" the lid switch is and what type it is?

Havent done chips in the past, but i suspect they may be PIA so there is that programmer on the other hand.

Toshiba forum is for users to users. Engineers dont bother to visit there unfortunately.

Chip removal is an art; and not everyone has the necessary skill or experience; especially with some of the current and recent kit. Much of it is designed to be dumped rather than repaired... Although where I used to work there were those who were suitably adept; but they were more the exception...

I've done it once or twice - with single sided boards; never with a double sided...; and it "was an age ago...".

I was thinking a direct (phone) call to Toshiba techies. If necessary going closer to the actual source itself (phone call to Japan?); or possibly letter to one of the CEO types... The latter approach often gets results other approaches don't.

A sweet approach, praising their kit and so on (flattery helps in most areas of life; if only to grease the wheels of movement even progress...) and saying you really want to be able to continue with item you have etc. as it's been "reliable" or whatever thus far, might produce some helpful response. I think you can see the idea?

The Japanese have long prided themselves on customer service - when contacted directly; and certainly if one happens to visit their home base.

A colleague years ago dropped into Canon in Tokyo - or wherever in Japan, with his Canon camera (film type). It wasn't working properly at the time. They took a look, said this will take a wee while; meanwhile have a visit around uor factory; and also lunch... After-which he was presented with a "new" camera...

Whether or not those days still exist - who knows; but no harm to try contacting Toshiba main base?

That is a lovely story trvlr , i may call Japan and see. On the other hand i have also pavilion dv-7 showing similiar symptons regarding BIOS so it might be worth to get proper programmer.

This is really long shot and more a test to see if...

Perhaps try booting with a bootable DVD? I'm thinking of something like a Linux variant disk; the one that comes to mind is of course ubuntu - ubuntu.com

You can download an ISO (free) there and burn to to a DVD; then try booting with it?

If it doesn't boot then clearly there is something "seriously" amiss; possibly as you suggest the on/off switch - although that the system at least makes starting noise... I'm not entirely sure it is the "missing switch"...

I have ubuntu and mint on my pc although the best for this task probably would be knoppix. I tried that my friend but this is clearly not booting problem , screen is dead all the time amd even taking ram out doesnt makes any difference whatsoever.

Ok... any bootable DVD would have done what I had in mind, which was to test the basic hardware etc. If it was simply the hard drive had died a death as it were, then the system would still have booted via the DVD and installed Linux variant into RAM. But if it won't boot with the disks you have then certainly this is a hardware issue.

I doubt it's RAM as there are assorted beep codes that emerge at boot up which would indicate RAM issues... And you seem to say there are no beeps and little noise etc; other than a few flashing lights and then silence and nothing else happens...

It "could" be a bios issue; not an area in which I'm by any means a genius or anywhere near that on such matters.

I seriously doubt it's the missing switch... but then if we can't find it to test..?

I just dun a very basic google type trawl - search using:

where is the lid switch on a toshiba satellite laptop

and found a whole slew of info.

These (not youtube) posts from here a while back makes interesting reading:

http://www.tomsguide.com/forum/6597...

http://www.ehow.co.uk/how_7591287_r...

http://support.toshiba.com/support/...

Perhaps repeat my trawl and have a look-see at what comes up? It seems the issue you describe is not entirely unknown; although the cause may not always be due to the lid switch...

thank you very much but ive seen it all , i think i failed to mention some details i already know but then again this way at least i wasn't suggesting anything
in the past i would simply say "the mobo is gone" , now im getting deeper into it and trying to find what exactly on the mobo is gone
so in the place where im now replacing/reprogramming bios isn't such a long shot

mmm... You sound a little like moi with this one. As if it was mine I'd be wanting to know the what and why... even if it was beyond repair (at least by me).

Keep us posted on the final discoveries and outcome?
