Dell Inspiron 1420 won't boot:
I was given a Dell Inspiron 1420 that won't won't boot.
Here's what I'm noticing:
- There seems to be a big delay before the machine actually powers on. I press the power button while it's plugged in and nothing happens for about 15 seconds. It then powers on.
- The screen lights up but there is no POST. The screen just stays lit permanently.
- At this point the NUM lock is lit solid (not blinking)
- I cannot power the laptop off. Pressing and holding the power does nothing. I need to take the battery out in order to power the machine off.
I've already taken the hard drive out, extracted the data for the person and put the hard drive back in. I know it's not the hard drive.
I took the RAM out and tried both in SLOT A but the same thing happens.
I didn't try either of them in SLOT B yet (will the laptop even boot with no RAM present in SLOT A?).
Any help would be appreciated.

it is almost a hardware issue
you need technical skills to deal with it

Hmmm. I was hoping to get a little bit more information.
Something along the lines of:
"I've seen that on a friends computer. he replaced the CPU and all was well."
-or-
"Chance are the motherboard is toast."
Etc.

i think you need somthing beyond swapping cpu ram ......etc
i Although i adviced you to do so first

first take battery apart and try to turn on without it

Already tried that. It won't power on.
I noticed that this laptop make/model was affected by the NVIDIA class action lawsuit so I'm thinking it has to do with the video card (NVIDIA Geforce 8400M GS I believe).
I can try buying another GPU but my concern is that additional damage may have been done to it.

Most likely its a bad motherboard, but it could also be a failed cpu. But first try with just the ac adapter in and the battery out then try with the battery in and the ac adapter out. Replacement motherboard can be found on ebay for $100+, and dell offers teardown guides on their website for repairs.
don't be hurry up i will walk through step one by one
now take a multimeter and test the output of adapter

On this board you cant replace just the gpu(8600m), unless you have some insane soldering skills, as the gpu is integrated on the motherboard.
then pull adapter cable from AC outlet and insert connector to DC jack of laptop move it gently do you feel it too loose ?

@jamietoner:
I did a quick search and it looked as if the video card is replaceable without soldering but I'm not 100% sure:

From what I am seeing on Dells website this system shipped with 2 video options an intel and an nvidia 8600m both are soldered onto the motherboard. The video card in your link is for an Inspiron 1520 and a Vostro 1500 and will not work on the 1420.
The part# for the motherboard with the nvidia gpu is UX283
The part# for the motherboard with the intel gpu is KN548

There are other things causing the problem mentioned
-make sure about adapter by swapping it with knewn good one
-swap cpu ram
-reflow by heat gun on gpu IC

-reflow under cpu socket

I was given the laptop to keep. The person didn't want it.
I'm just trying to decide if it's worth it to replace the motherboard.
There's an eBay item for $130 that you send them just the motherboard and they'll put the newer NVIDIA GPU on your existing motherboard and send it back to you:

I don't know if in theory, that'd be a better bet than ordering someone else's used motherboard that probably suffers from (or will suffer from) the same problem, ya know?
What to do, what to do...

I have never used one of those repair services but it has good reviews and may be worth a shot. If the systems not going to play games another option is to order the motherboard with the intel gpu.
ASKER
Yeah I was thinking about getting the Intel board.
Either option seems like it's going to be about the same price.
Thanks for the help guys.
Looks like I'm going to need to think about what path to take.

yes but that link talks about a group of predefined problems it didnt say we will repair any (no display problems) if you do not like to do the steps i mentioned it is better to take your laptop to a professional repair guy
cuz
sometime software in bios ic go corrupted and reprogramming it resolves the problem
