[marcellodj]

The problem:
when i connect the ac adaptor plug, the system power on itself, fan start spinning,led amber blinks,but no video.
GPU,chipset,cpu goes warm, what you think a gpu/bga issue or mosfets/power issue.

Any help will be appreciated.

Tnx

A lot of Dells have the amber light flash problem, with various causes. I would google that model and see. I have had many of the Dells, do this from bad Jacks, wrong watt powersupplys, bad mosfet, and even ground issues. Best of luck on that one. let us know what you find.

Does it have an 8600M?

Re: [DELL-M1530] Power on but Novideo

Most M1530 failures I see are video related. It either has the Nvidia 8400M or 8600M, both of which were failure prone.

Try to reflow a gpu & chipset.

Re: [DELL-M1530] Power on but Novideo

Just reflowed all the bga on the board; no result.
I think one of these babies need to be reballed (gpu bridged?).
Will keep you informed on the process.
Best regards.

Re: [DELL-M1530] Power on but Novideo

if it does use a GF8400m-8600m on a MXM card, replace it. (preferably with an ATI)
those die like flies. reflowing them only works for a couple weeks at best (if at all)

Re: [DELL-M1530] Power on but Novideo

@ Scenic, it s gf8600, reballed now and works perfectly.
Reball only as last chance,I hate do reballing (time consuming and from a business perspective time is $); i prefer do reflows, i have machines reflowed 1 year ago, still working fine.

Same here, the quality of the cooling system plays a big role as well.

I have one in here, powers on and shuts down in 4 seconds. even if I press power button or not my power supply shows 0.20Amper while plugged in. is this a Nvidia chipset problem too ?

0.20Amper while plugged in

I dont think so, 0.20 could be other problem.

indicates a faulty chip, fet, or capacitor. Check SIO, LAN Chip, Sound Chip for overheating.

first thing to do is always check coils for short. check first for 3.3 and 5 volt if present (i suppose yes as it start and then power off. after check all coils for short u can trace back where the problem is.

thanks for all replies, did a visual check and realised there is a small oxidation due to liquid contact, sorry, I forgot to take a picture cleaned it and now I post this from that computer I appreciate your interest, have a nice day !
