My Dell-600m failed

[cjoseph2]

I was using my 2.5 yrs old Inspiron 600m laptop. It was plugged to the
AC adapter and suddenly the laptop turned off. I was trying to switch-
on using the power button, and it would not turn on.

The green LED on the AC adapter would not turn-on either. Then I
removed the AC adapter from my laptop, still the LED on the AC adapter
would not turn on. After that I removed the adapter from the wall plug
and re-plug in without connecting to the laptop, now the LED would
turn on. But as soon as I plug the AC adapter to the laptop, the LED
on the AC adapter would turn off. The battery is fully charged and the
AC adapter is also working. I dont know where and how things went
wrong.

Now I am not able to turn-on the laptop at all. I really have no clue,
what would have went wrong. Some fuse or some power supply
electronics??? Please help!!!

Thanks,
Clement

It appears the AC adapter still works but it would be good
to check it's output with a multimeter. If it is not
permanently sealed shut you might also open and inspect it
(while disconnected from AC).

You probably have a mainboard fault. You could disassemble
the laptop and look for problems, probing around if you have
a multmeter but unless you see an obvious fault or have a
separate power board that can be disconnected from the rest
to isolate it for measurements while connected to the AC
adapter, there is not much more that can be done except to
decide whether it is cost effective to repair it and if so,
if you would want to source and install a replacement
mainboard yourself or pay someone else to do some part or
all of this.

You might also search usenet or Google (for Dell forums) to
see if there are any issues specific to your model, as there
are none I'm aware of but could easily exist.

Many laptops react that way when the battery is bad. One would think
that when AC is used to power the laptop it would be independent of the
battery, but that is not always the case. You might borrow a battery to
see if it behaves differently.

Or run without the battery to "elliminate it from enquiries"!!

The adapter is good. I am able to use the adapter on another laptop. I
tried to run without the battery, still it does not turn-on.

If the motherboard failed, should I replace the processor or I can re-
use the same processor??

I am not seeing anyone explaining a similar issue in any of the
forums.

Some will not power up if no battery is present. I saw an IBM that was
that way. One would think it would, and it would make finding the
problem a lot easier. Perhaps too easy???

The processor is likely fine and you only need to replace
it too if it doesnt work on the replacement motherboard.

 

[DaveW]

There is no fuse. Either the PSU or the motherboard has most likely passed
on.

I've never seen any Dell laptop do that.

I've never seen any Dell laptop do that.

I shall keep that in mind, I wish ALL of them behaved that way.

Agreed.

Many laptop mainboards or (if it's separate) power boards do
have a fuse on them. However, it is often soldered on, and
it doesn't blow all by itself - the problem causing it to
blow would need fixed first.
