posted 10-19-05 : Dell NEEDS to recall 5150s for AC adapter problems!
Search on "recall 5150" and see all the listings there! We are all out $+++, time, hassle and still no long-term functioning computer no matter what we do!
Still the same problem - two motherboards and nada! Maybe the power supply isn't providing the correct signal on the data pin, is there a way to check?
Thanks ccook129, but I instead reverted to the original board, desoldered the power plug, cleaned the contacts, resoldered and reinforced the plug with epoxy. It then took a new power supply to complete the repair.
So it looks like to me that sometimes the plug breaks from the board and shorts something in the power supply, probably the data pin so that you still get 19.5volts but the power supply ends up looking foreign to the system because the data ID on the center pin isn't available.
Just what worked for me with no help from Dell. By the way the replacement board is going back for a credit whether the like it or not.
I am trying to help a friend with the power problem on her 5150.
As "blind dumb luck" would have it, I found that pugging in an external monitor makes the 5150 power up and run fine. Charges battery also.
I thought that perhaps the problem is that I am missing ground throught the AC adaptor/plug. To verify I took a wire jumper from the grounf lug on a power strip and held it against the stud on the external monitor connector on the 5150. seems that I am correct. 5150 powers up and runs fine.
I haven't "field stripped the 5150 to see if I can find the cause of the problem yet but will post results here.
