Dell Inspiron 1150 not starting

Machine: Dell Inspiron 1150

Symptoms: (1) on pushing power button w/ battery in, power light flashes twice, battery light flashes once and nothing else (2) w/ AC adapter and no battery, power light flashes once, nothing else. (3) same symptoms when drives, memory, modem, keyboard, display stripped.

So far: replaced palm rest and replaced system board, but same symptoms.

Curious whether it is something with the fan. When fan plug removed, power light stays on for a few seconds, then off.

Any suggestions?
Thanks.

...more on Inspiron 1150. With the fan cable disconnected, goes into POST, with the fan connected, symptoms as above...both with old and new motherboard (I'm about to return the new motherboard to Dell). Can anyone confirm that this is definitely a fan problem and that things will be fine with a new fan module?

I met same problem as you. I disconnected the TOUCH PAD wires ( just under keyboard) and just use battery. The computer start normally. So the power PA-10 is bad and TOUCH PAD including three lights is wrong.

Hi,

I think the problem in DELL 1150 is from power sparking. The fault item is the one protect element marked U1 which is in touch-pad board. You can just disconnect it and computer will work fine, but maybe like me should find new power PA-10.

Thanks

I've completed the Dell chat help session... based on the Anupau's troubleshooting, he's identifying a video card issue. So he's sending for a technician to come out to the house for replacement. I'll follow up with a report here...

Are we all sure this is the same problem? So far, we've got several different components that "could" cause the issue. It might be a better idea to split this thread up.

To the original poster-- if your fan, being unplugged, allows the unit to POST, then you're probably right. If you're in warranty, you might need your heatsink/fan combo replaced by Dell. If you're outside of warranty, I guess you're buying one on your own...

It seems to be the same problem with my laptop but when I try to power on this what happend:

1-- the power led is on
2-- The cpu fan start and the caps lock begin to blink
3-- try to access to the CD
4-- I don't see any video signal even in an external monitor
5-- Then goes down after 10 seconds

I remove keyboard, CD, HDD, TOUCH PAD, modem, ... and the problem still there

Any Idea?

Is anyone know this part including character. Thanks a lot.
