dim lcd problem being caused by the Mobility Readon 7500?
Hie. I have an IBM thinkpad T42. Its been giving me the following problem for a while;
When I power it up at times it gives me one long beep and two short ones. In this instance the screen will be blank. After 15-20 seconds it turns off. Other times it boots normally but the screen is EXTREMELY dim. Without applying an external light source (a torch or something) you cannot see anything on the screen. According to the manual it appears I have a system board problem. I am not ready to let it go so I took it to a local repair guy who told me that this particular part (Mobility readon 7500 (m7-csp32 216q7cgbga13) needed to be soldered because it was loose. However, he says there is a chance that things could go either way i.e: he solders it and my T42 works as good as new or that will be the end of it and I would have to just buy another one. To show me that he knew what he was doing he applied pressure to the mobility readon part and booted up the t42 several times and indeed it started up without the beeping and dim screen. Is what I am being told really the case? Can I get this particular part replaced Mobility readon 7500??...or should I just get another system board or a new laptop altogether?? Please advise me on the best possible solution to my problem coz I don't know what's what anymore...
