The little bit of circuit board, that is usually found underneath the plastic shell of your laptops screen casing, might be the reason behind certainly one of the most typical problems related to screen failure and, more specifically, dimness, or darkness to the screen it self.
The main reason for the inverter is simply to give power to the backlight. The way it works is straightforward, it takes energy from the laptop itself with a small inverter lead that runs from the motherboard of the laptop, often it's an immediate lead on its own, other times this lead could be linked into the inverter through the LCD cable (the lead that runs from the motherboard to the back of the screen itself), giving the screen its visual display.
At one end of the inverter, usually the left end, the lead that provides it energy is plugged into a tiny white socket and from the other end, usually the best side, the backlight lead from the display is plugged into still another white socket. The backlight is just a very small, thin, long, very delicate light bulb that runs along the very bottom or sometimes the side of the screen.
The issues linked to the inverter is dimness or darkness to the screen typically or flickering of the backlight. Sometimes it can stop the display form working at all however not generally. A standard fault with laptop displays is a dark or gray screen, usually it is believed that it's the backlight that's at fault, often this may be proper, however more often or not it's simply the inverter not operating, or not giving the backlight the energy it needs. The inverter is generally cheaper to replace than the backlight, since the backlight is extremely vulnerable and may be easily broken. A restoration of the inverter is achievable, although often labour charges on repairing the inverter can sometimes lead up to being more expensive than replacing it on some occasions.
When it comes to purchasing an inverter most companies will need the part number which is usually printed on a bar code on the exterior of the inverter but sometimes you may need to look carefully to find it. If your lucky then you gets away with just stating what your notebook make and model is, for example I have an Thinkpad T22 and I need an, we try our hardest to discover the inverter with just these details, however often you'll need to offer the part number; listed here is an of a number from the inverter for an Thinkpad, (10L1402). This inverter can also be suitable for the IBM T21, and T20 all three laptops in general are basically the same besides the model. garmin nuvi 1300
