Laptop boots ok. No fan on startup now + power light flashes
The laptop boots fine. It used to have the fan going on boot up, which was normal enough. There have been some rattly sounds coming from the fan in the recent months, but it didnt seem to be a big problem as the laptop has continued to work fine until yesterday.
Now there is no fan going on boot up just a whine-ing sound, as if the fan is trying to move.
The power light flases on and off. (not sure what this means)
(From what i recall, there does seem to be additional fans that come on when the laptop is working extra hard, and i dont know if its safe to keep using it with this in mind(i.e. that they will come on if it gets too hot). However, im not chancing turning the thing on when there may be no means to cool it!)
Any suggestions as to how to trouble shoot this would be much appreciated.

Do any lights come on when you press the power button? If not, did you get all the cables reconnected properly? If lights come on or fans come on when you press the power button, then it sounds like the screen has gone bad. That is the symptoms you are describing.
If you had no issue in safe mode the only thing I've seen like that is a virus that cuts of your use of I/O ports. boot into safe mode and try doing a system restore to a time before this problem occurred. IF that doesn't solve the problem try doing a clean install of the OS
Try removing the battery, plug the power cable into the laptop while it is already plugged into the wall then hold the power button down till it comes on. If/when it works, let it boot all the way, shut it down and put the battery back in. It should boot normal again.
It happens due to a relay tripping after a power surge. That procedure resets the relay. Works on a few name brand laptops, including Toshiba.
Sounds like either your hard drive's going bad,
or the boot device order has been changed in the BIOS.
When you check the boot order to make sure the hard drive should boot,
you could also see if it has boot devices for a usb flash memory stick
or a disc, e.g., CD-ROM. If so, and you set it to boot, you could download a "live CD," e.g., Knoppix or Ubuntu, and use it to make a bootable usb stick or burn it to a CD, and put it in your laptop before you power it up.
If it works ok running from the live image, you know your hard drive is the problem.
Here's a link to a good article that will help you to troubleshoot the startup error. You might also check Toshiba support online and see what the error light code indicates.
I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread. If I've managed to answer your question or solve a problem, please take just a moment to rate this post....thanks!
See if you can run the Pre-boot System Assessment (PSA) diagnostics. To run the PSA+ Diagnostics on this system, perform one of the following actions: 1) Hold down the <Fn> key while pressing the power button. 2) Turn on the system, press <F12> at the initial Dell™ logo screen, and select “Diagnostics” from the boot menu. 3) Disconnect the AC power and remove the battery. While holding down the power button, insert the AC connector into the back of the system. The system then starts and the message “Diagnostic boot selected” displays. The system then launches the PSA+ Diagnostics. According to Dell specs, there is no error code listed that you described, (Flashing Caps LED). Also try reseating the memory modules, (you might want to try this first). Your responses are intended to improve the level of service provided. Please show your appreciation by rating your experience. Thank You.
Its late, so just to make sure I'm not brain-dead basically your laptop runs fine as long as its powered by the AC adaptor but dies fairly quickly while running via battery.
This is very typical of a battery that will no longer hold a charge, not normally a user repairable item. It could also be that the charging electronics (in the laptop) isn't charging the battery, again not a typical user repair job. About your only option short of taking it to the repair shop is buying or borrowing a battery as a test.
Have you considered it could be the battery has died. Have you tried external power? If the battery is OK then check the battery contacts to make sure they are clean.
Has your power supply died and it won't power the laptop or charge the battery?
It could be the motherboard but I'd put my money on it's power supply or battery. Without more details being supplied.
