You may have a faulty inverter, it supplies high voltage to the CCFL lamp.
If your laptop appears to boot up and the hard disk LED flashes, then the problem is probably a back light fault. This can be a faulty inverter or a faulty CCFL lamp. Please click on this link and follow my instructions to identify the fault and possible fix :- http://www.fixya.com/support/r3598095-faulty_laptop_lcd_screen

SOURCE: My Laptop is Toshiba Satellite A350 series

If you have a Toshiba Recovery CD you may be able to install XP, otherwise :-
You need a Windows XP installation CD together with the installation Product code.
To install Windows XP insert the CD in the laptop and boot up with the CD and follow the screen instructions.

You can download any/all the Windows XP device drivers for your model laptop from the Toshiba WEB site from their download page.
Make sure you enter the model of your laptop so you can get the correct drivers.

Hi,
There are some problems which may cause that:
1. Memory defect.
2. South bridge defect.
3. Bios Defect.

Try this one to find out which one is your problem:
1. Remove your battery and plug the external monitor via VGA or HDMI port and turn your laptop on with the AC cord attached to the outlet. When you can see its welcome screen via external monitor then it has a problem in its LVDS driver. But when you see nothing then try the second step.
2. Unplug the Cmos battery located under the palm rest on the left side of the touch pad, wait for about 2 minutes and then you can try to turn it on. When nothing appears on the screen then the problems may cause by your south bridge defect. To know this problem just touch your south bridge while it is turned off, when it is warm then your south bridge is working but something wrong with its pin. When it is cold then your south bridge has a problem in it.

When you see the two above step yield nothing then better for you to bring it to a service centre.

Good luck

ANYONE KNOW WHY MY TOSHIBA SATELLITE L645 BECOME BLACK SCREEN BUT THE PROGRAM STILL RUNNING ?


you probably don't need a new screen it's probably your screen inverter that's going. It's just a small strip at the bottom of the screen wjth a little circuit board. If you google screen inverter and the make and model of your laptop you'll see what I mean.

Hi , I have a toshiba satellite L645 , when i play game suddenly my screen laptop become black and a few minute become normal then happen again , what must i do ?


Your laptop cannot handle the game. It's too intense.

More in-depth;
Your graphics are Integrated Graphics.
It is Intel HD Graphics,

http://en.wikipedia.org/wiki/Intel_HD_Graphics

Uses an Intel Pentium P6200 processor,

http://en.wikipedia.org/wiki/List_of_Intel_Pentium_microprocessors#.22Arrandale.22_.2832_nm.29

That processor is based on the Arrandale Core.
(32 NanoMeter architecture)

Means It is the first Intel HD Graphics. 6 Execution Units.

Be lucky if it could fight it's way out of a wet paper bag; graphics performance speaking.

Also if you have never had your laptop partially disassembled for cleaning, (Fan/finned Heatsink), I would advise you to do so, and avoid a lot of trouble in the future. (Maybe near future)

Do it yourself? Sure IMHO. You, though, will have to be the judge,

ESD wrist strap, and it's alligator clip attached to a good ground source.
Average cost is $3 to $6.
One example,

http://www.radioshack.com/product/index.jsp?productId=2103245

Set a large metal serving tray (Unpainted), on the table you're working on, and connect to it.
Or a large metal knickknack. (Unpainted)

Use a mutli-compartment container for the various screws you will remove. Label each compartment for the area the screw/s come out of.
SOME screws look VERY similar to other screws.
Advise do NOT mix them up!

Use Q-tips, a soft small brush, (Makeup brush?), and a can of compressed air for computers.

Want to see how bad it can get, and you won't know it until you see it?

I have Toshiba 14" Satellite L645 i5450 notebook


It is possible to connect a modem to the laptop. Connect the modem to the laptop using the telephone style socket on the laptop. The mother board will then pick this up and load the relevant drivers for your modem.
If you are not sure, contact Toshiba online. They are extremely helpfull.
Hope this helps.

the Satellite L645 line has optional built in analog modem
but can not find info on you specific model

this line does not seem to have a serial port nor pc card slot
therefore can not support a analog model unless you can find a manufacturer of a usb model

but if your want to connect to a dsl or cable modem that is done thru your rj45 port with a ethernet cable
