Toshiba laptop will not startup

Laptop will not start up Toshiba Satellite A215-S7472

Upon first power up, the unit boots up yet, the screen does not turn on. Disconecting the battery and leaving it out you must repetwedly unplug and ruplug the unit in power up and wait for screen power. All is fine untill windows tries to reboot for updates. shut down requires the process to be repeated. I downloaded new drivers for the display to no avail.

Without being about to do a HANDS on inspection of the laptop, it could have a couple of possible problems.

Here is my Best guess as to the probable cause. You have a loose/damaged connection on the Display screen. More than likely the power supply line to it. When it reboots it cools enough to pull away from its connection. Then gives you trouble rebooting until you apply and remove power several times. Why this is working by my theory is that each time you apply power it is sparking in that loose connection and slowly warming it back up until it finally connects again. Then all is fine until you reboot again and start the process all over.

This is a theory and I Can NOT guarantee that this is the problem. If it is. Then unless you are experienced at dealing with small electronics and high voltage. I would strongly recommend having it looked at by an experienced technician.

Sorry I couldn't be of more assistance

My toshiba satellite a215-s7472 screen is very dim can hardly see anything what do I do too fix it I tried ajusting the light .


Primer:

An LCD screen does not produce light by itself. It needs an additional light source.
A Backlight is the additional light source.

A Backlight can be a CCFL, or a series of LED lights.
(Two present technologies being used)

The Toshiba Satellite A215-S7472 Notebook PC uses a CCFL.

A CCFL is a Cold Cathode Fluorescent Lamp.
Similar to Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale.

(Average size is 2mm by 334mm. In inches that is;
Approximately a little thicker than 1/16th of an inch Thick, and a little over 13 inches Long)

A screen Inverter is used to convert the power (Electricity) from the laptop, for the Backlight, and LCD screen.

Point of all this?

90 PERCENT OF THE TIME the fault is a bad Inverter

http://www.zkarlo.com/selected-zkarlo-part/inverter-board-p907.php

HOWEVER, the Backlight bulb is located inside the Screen Frame, of the LCD display assembly.

An LCD screen is composed of layers. These layers are held in a specific pattern, by the LCD screen frame.

This is a thin metal frame which surrounds the LCD screen layers, and has Philips head screws which hold the frame together.

NOTE*
The procedure is fairly intricate.

[ So far I have only seen listings for the LCD screen itself, and not a separate CCFL Backlight ]

My Toshiba satellite a215-s7416 is asking for a password upon startup, i dont know what the password is. The screen looks like this: (http://www.r-obi.de/paperclip/locked3.png). How can I guess or remove...


Remove the ram cover, with laptop switched off
Remove the 2 ram modules and insert one in the slot that is furthest away from the motherboard
Just underneath the ram is a thin plastic sheet, gently peel back to reveal two solder contacts
they should say B500, TOUCH THESE WITH A FLAT BLADED SCREWDRIVER while powering on the laptop, the bios password should go.
Replace ram and sheet, replace ram cover reboot.
