Question about Dell Latitude C640 Notebook

2 Answers

Your solution was spot on...

What kind of morons are out there on the net? Your answer was exactly what i was looking for. FL1 seemed fishy to me as well. People ask for help to DIY FIX their laptop (Including replacing a cap or resistor etc.. and there are so many **** on the net who think they know a little and answer them with "You need a new mainboard"? What part of fixing is that??? freakin **** .. anyway, I would like to keep in contact with you because I am constantly repairing laptops and there are few who know component level... I still cant beleieve his answer was voted best??? "better off buyin a new board"??? Blows my mind.. but ... Hats off to you sir! Sincerely, Rod Sinclair, Newfoundland, Canada

    What did you mean by "a chip labeled FL1 on the board was shorted and once removed and continuity restored instead of the chip all is well.." How was continuity restored? Do you mean that the FL1 can be bypassed? If so please explain. And if you have any idea what this component is reply with the answer.

Hey there, I was refering to the C640 solid lights/no post/shut off issue... the point I was trying to make was, people narrow there problem down to a mainboard issue and then ask if someone knows what might be wrong with it, and A LOT of times they get a reply of 'mainboard shot go buy another'? If I had thrown away all the laptop boards that I have had issues with I wouldnt make half the money I do.. I hunt down good laptops with major problems.. pay little for them, fix em and sell them for less than what there worth and still make a huge profit. I honestly get off on finding a bargain laptop and fixing it... and not too often do I not find the issue.. 90% of all laptop mainboards that just up and die with no abuse or physical reason can usually be fixed with very little work. When I do get stuck I try to look to the net for maybe a little tip or something I missed and am usually shocked by what I find... It makes me think that most that really know there stuff must not post on these sites... its like the blind leading the blind... but anyway, the guy i posted about had found the problem with the dell c640 board, fixed a few this way and he was right... a chip labeled FL1 on the board was shorted and once removed and continuity restored instead of the chip all is well.. the next guy says... board must be dead, you should buy a new one and he got voted top answer?????

I was just curious to the original problem post and who exactly you are referring to here. I also fix alot of laptops and do some circuitry component work as well, and I can always use a bit of info from time to time, especially from someone who knows what their talking about. Unlike a few I've encountered that their qualifications are "I took my dad's old laptop apart once", and.... I would like to see the original problem you're talking about and talk to the tech, any info would be appreciated. Thanks.
