Hi.

I am going to school soon after many years and I don't have much money. I still have a Dell Inspiron 640M around here but with buzzing screen. I changed the inverter but I don't have much money for a screen and the ones on E-bay are not in my budget.

The screen is 14.1" and can be in some other models. If a generous donator can sell me one really cheap it could help me more than ever.

Thank you for reading.

Thank you and I know the chances are extremely low. Before it was me who builded up computers and gave it to poor people. Now I'm in this situation. hehehe

Thread updated to make it legal in the section. ;)
Let us know if you find one, Krazy.

What's the screen's resolution and finish (glossy, matte)?

What do you mean by "buzzing screen" sounds like power issue

Trying to help. If there is an audible "buzzing" sound it would be a power supply issue. There are capacitors as well as inductors in the power supply circuitry. A few years back Toshiba had a noise issue that was related to unglued cores in series inductors. Even a high-frequency PWM inductor can resonate in the audible band if the fundamental frequency is an even multiple of the resulting noise.

Screen as been unbolterd and all laptop is torn appart. Clearly from a place where there is NONE power going there. Even the screen has been splitted to make sure about what you tell me.

"buzzing" noise is coming from the inverter board, or motherboard?

Found out it's the CCFL light itself that start to go out. Making the same buzing sound as a neon light burning slowly. i will try to order one in case it solve my problem.

I don't think so. the Dell 640M is widescreen and the 1100 is more square.
