The small little bit of circuit board, which will be usually found underneath the plastic cover of your laptops screen casing, might be the reason for one of the most common issues related to screen failure and, more particularly, dimness, or darkness to the screen itself. The primary 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, sometimes it is a direct lead on its own, other times this lead may be connected in to the inverter through the LCD wire (the lead that runs from the motherboard to the back of the screen itself), providing the screen its visual display. At one end of the inverter, usually the left end, the lead that gives it energy is plugged into a small white socket and from the other end, usually the best side, the backlight lead from the screen is plugged into yet another white socket. The backlight is really a very small, thin, long, very fine bulb that runs along the very bottom or sometimes the part of the screen.

The problems associated with the inverter is dimness or darkness to the screen generally or flickering of the backlight. Sometimes it may stop the display form working at all however not often. A typical fault with notebook monitors is really a dark or gray screen, broadly speaking it's assumed that it's the backlight that is at fault, sometimes this can be right, however more regularly or not it's simply the inverter not operating, or not giving the backlight the power it requires. The inverter is generally cheaper to displace compared to the backlight, because the backlight is extremely vulnerable and could be easily broken.

On some occasions a restoration of the inverter is achievable, though often labour costs on repairing the inverter can occasionally lead up to being more costly than simply replacing it. When it comes to getting an inverter many companies will need the part number which can be often produced on a bar code on the exterior of the inverter but sometimes you will need to look carefully to find it. If your lucky then you gets away with just stating what your notebook make and type is, for example I have an Thinkpad T22 and I need an, we try our hardest to find the inverter with just these details, however sometimes you'll need to offer the part number; listed here is an of a number from the inverter for an Thinkpad, (10L1402). This inverter is also suitable for the IBM T21, and T20 all three laptops as a whole are essentially the same besides the processor..
