Hello peeps!

So one of my neighbours (don't know which one) left a broken laptop down by the bins, so I have taken it home in the hope of nursing it back to life.

It is an HP Compaq nx9110, like this one.

The charger is still the original one - the little green light on the charger still comes on.

When i plug it in, the little lightning bolt light on the front of the lappie comes on, stays on for about 10 seconds and then goes off. Pressing the "on" button does nothing at all.

I have opened her up and all seems well - 512MB RAM, 60GB HDD, CPU all look intact, so does the battery.

Anyone have any ideas?

Don't just want it to be discarded...
 
Something else might be bugger'd.

What state is the fan & heatsink in? If it's clogged up, then it's a dead CPU.
 
Got one of those lying on my desk in working condition minus a hard drive, unfortunately it does not belong to me.

I would start by stripping & cleaning it. Some of them use a P4 desktop cpu I think.
 
yeah remove the battery completely plug in charger and try and power it on also you shouldn't go through other people's trash its very impolite!
 
Check where the power plugs in may be the jack is faulty and disconnects every thing

I shall have to go deeper. Take it all to bits and put it back together again. I will not let her be thrown out. Looks like it was top of the range like 10 years ago. It has every port and slot imaginable. Such a nerd. Sigh.

Like a bad connection between the socket and the rest of the board perhaps? That also looked fine...But will probe...

What CPU does yours have? The one on my desk has a desktop P4 and the thing runs fsck hot. With a bit of extra ram linux or xp will still be fast on it. Yip, got lots of ports.
 
I have the nx8220 which I've been trying to fix up and have been successful.

Guy came today with a new keypad.
I upgraded the RAM to 2GB DDR2 800
Hard drive I'm going to upgrade to 100GB hopefully tomorrow.

Putting alot of love into this laptop.
 
I revived one of those last year displaying the same symptoms.

This is what I did to get it working again.

1. Find and download the Service/Disassembly manual for the particular model I dealt with.
2. Strip the entire thing down to component level using the info from the manual, be exceptionally careful with the ultra thin ribbon cables, tear one of them and you can put it back in the bin.
3. Clean the entire motherboard with meths or similar gentle solvent. Pay attention to the copper CPU cooler - I found the green gunk from the CPU cooler had got all over the motherboard and was shorting out the tracks,
4. Soak the copper part of the CPU cooler in lemon juice and clean with an old toothbrush.
5. Clean the contacts of all the cards that fit into the motherboard as well as the memory module with a soft (those rubbery white ones) eraser.
6. Reassemble carefully.

And voilà ! I have a working laptop again. Installed Windows 7 Starter I had lying around and it works great as a spare computer.

Side note ..... I also found one of the memory modules to be faulty after a few days of use so replaced it.
 
Boet, if worst comes to worst and you really want help.
I met this guy today (who brought my new keypad for laptop, and installed it) who can help.
He works for HP (laptops etc) and would probably be able to help you and if need be, get you parts for cheap (original HP, but probably 2nd hand)

PM me for his number.

I did all of that. Well most of it. Same result. Ram and cpu looked pristine. No sign of blown circuits either. Or loose connections. Sigh.

Surely then it would work with just AC

Which it still doesn't.

Not even a bit. The fans dont spin up or anything. Guess that could be something as simple as the "on" button being broken.

no i am saying if he thinks it is the charger module it should still work with AC then, i know you said it doesn't ;)
 
Just because the light on the charger comes on doesnt mean that it's working.
See if you can get a multimeter and test the output.

Also you might just have to accept that it's truly broken (There is a reason why it was thrown away)
