No Display with external monitor
The original Dell Inspiron 640m laptop display stopped working 2 years back and hence, I started using external monitor. Now, my Dell Laptop stopped displaying on external monitor. I tested my monitor with another computer to be sure that the monitor is good. What do you think is wrong? If it is graphics card, then is it easy to replace? How much would it cost? Also, if you sell display screen for this Dell Inspiron 640m, then how much would it cost? Are your parts guaranteed for 1 year or so?
Is this a good question?
