Screen locks up.

The actual switch is rare to go, the DC jack in the laptop is more likely the issue and will require a complete tear down to access.

You typically get that message when the hard drive has crashed or if you're lucky there is a cd in the laptop.

Did you have any important information stored on the laptop like pictures and documents?

At least 2005. The drivers on Toshiba's website show the earliest date of 2005.

Hi,

GO to this site and enter your model number and you'll get a list of driver. Download and install

It could be the motherboard as it is what is powered initially and distributes power to all other parts.
such a problem can only be diagnosed by checking physically but if you are asking whether a motherboard can be the cause, then yes it can

Yes, there is. Match the type of drive (Serial ATA or Parallel ATA) you get with what you have. Make sure your Satellite sees the drive in the BIOS. For drives larger than 120 GB, recommend operating systems Windows XP (Service Pack 2 or higher) or Vista. Older OS's have a 137 GB limitation (they only see the first 137 GB of the hard drive despite its size).

If the M35-S320 case is OK and the M35-S359 screen is OK and will fit the M35-S320 then I would swap the LCD screen lid and inverter over to the M35-S320 including the hard drive from the M35-S359.
It would be less work and with luck it might boot up, if not you might be able to do a system repair, worst case, you will need to reinstall Windows. Plus you have a spare drive from the M35-S320 which you can use as an external hard drive with an USB hard drive adapter case.

ok
when u power up the laptop press "del"or F2 or F5 to enter in bios .then load optimal defaults settings.then save and exit.
then check.

Thanks for that.

Ok the onlything that springs to mind is:

1. The bios needs to be reset asit has lost settings. This could happen IF you have installedsomething OR if it has become corrupt. Just access your Biosand reload the standard default settings.

2. Your hard drivehas a fault. The best thing you can do is to boot up from youremergency floppy (if you made one) or from your original windows CD. Once done, simply run scandisk/chkdisk/defrag and let it do what itneeds.

Sorry I could not help you more, but that is the onlything I can think of that would be stopping you booting further. Personally it sounds like the bios has lost settings and may betrying to boot from another drive ... but of cause it may be thatyour hard drive has become "sticky" or has errors that arecausing the problems.

Good luck with it.

Is this a Windows log on password or a bios password?
