Hi guys,
Having problem with compaq V3000 V3219TU. When i connect power adapter (with/without battery) dc in blinks continuously. absolutely nothing happens when press power button. no sound, no led no nothing. i already tried another dc and nothing changes so dc cable is not the problem. and for sure power adapter is working. i removed all parts so problem is not ram or hdd. also checked power button-mobo connection and it seems fine but cant confirm it since i dont have a spare one to test. im not quite sure but i think if graphic chip had any problem laptop still would power on. anyone with idea?
thanks in advance

So your saying the laptop works fine when using the battery, but wont run strictly off the power cord?

It must be a motherboard problem, or at least the part where the connector connects. Though it seems strange that it would charge the battery if that were the case.

if this is not what you mean, then please be more specific.

hi Micro,
no it doesnt work at all. nothing works, nothing even tries to power on nor the battery charges. condition is same with and without battery. the only difference between lying dead and power adapter connected is when i connect power adapter there is a fast blink at dc in port (nothing at battery or power led)
i'd say a dead motherboard but thought maybe blinks made me think there might be something wrong with dc cable or connector. dc cable is not problem as i tried a working one. thinking about desoldering connector and see if there is anything wrong it but thought maybe someone came across a similar problem and might suggest something useful before i bury motherboard :D

I would try to solder the connection, though if there is a problem, you could most likely see a crack on the mobo a few inches from the power connector. (due to flex in the mobo it prob would not have broken right at the connector.

I would also look inside the connector for a bent pin or the outer connector being pushed away. It is hard to tell if the problem is that the power is not connecting and connects when you remove the power cable, or if it is just a quick discharge. You could try unplugging the power from the wall and see if you get the flash. You will have to give it a couple of seconds as the dc converter in the cord will hold power for a few seconds.
