hp mini 110 doesn't turn on

Thread Starter 
So I was working on a friend's hp mini 110 netbook. BSOD was the problem originally.

The problem supposedly started when the charger was replaced since the old charger was sorting out.

I booted from my flash drive with winXP recovery console, then battery died.

After connecting the charger tried turning it on

Now it doesn't turn on at all. Power and wifi leds are on and hard drive led is blinking rapidly but screen stays off.

CPU fan doesn't spool up either, hard drive does though. Tried connecting it to external monitor with no results.

Tried hard reset and cmos reset. Tried to turn it on with disconnected hard drive and ram. Tried different ram.

Tried turning it on with only charger plugged in without the battery. I'm running out of ideas.

Is the motherboard fried?

Try finding an USB optical drive and booting up with an installation disk first. Is the replacement charger having the same specs as the old one?

cheers ...

But I can't even get into boot menu or bios since screen stays off. I'm not sure about charger, It's not my computer and I've never seen the original charger.

Understand what you are saying, some machines BIOS are wired to go straight to the boot section of the OS (hard drive or installation disk) without ever showing BIOS screen. You mentioned that the hard drive LED goes on, I am just suggesting trying an installation disk over optical drive and see

Search HP site to see what are the specs of the original charger and comparing it to the replacement unit

Hm ok I'll see if I can find one, thanks.

Do you think it could be a problem with hard drive?

If it is not the DC socket on the motherboard, it will be the graphics chip on the motherboard... You can test the DC socket with a multimeter, but it involves stripping the netbook down completely... If no joy, it will be the GPU, ones with XP or Vista overheated badly and caused the solder on the GPU to degrade.. It can be fixed by 'baking', but like most things a pro repair job will do and then ditching windows and using linux (they were shipped with SUSE linux)...

Nope. Motherboard appears to be fine. No burnt capacitors. I took heat sink off GPU and CPU and turned it on for a few minutes, both CPU and GPU seem to be heating up, though GPU is heating up a lot more, no matter how how it gets though, fan stays off. I'm out of ideas now.

You have nothing to lose - try baking the motherboard. Search the forum for tips of "bake / baking"

I knowit's been a while, but i finally got some free time to do it.

So i bought a cheap heat gun, then baked GPU.

It didn't work. Next day I tried it again, but this time I baked CPU and GPU, and it worked!

So now it turns on just fine but it still has BSOD, so I'm working on that now.

The only problem now is that heat sink gets really hot after a while, and after about an hour image on a screen is all messed up with lines running up and down.

What kind of thermal paste are you using? Trying copper shim also?

so far I only tried ceramic

I got blue screen fixed, but after about an hour of running screen starts to get lines all over it and it freezes, presumably because it overheats.

should I try to bake it again? maybe it didn't bake right?

Sure, try the baking again. Did you browse through the bake / baking threads and posts? And use something else other than ceramic paste.

Yes I did. I decided to use heat gun instead of doing it in an oven like a lot of people do.

Which paste would you recommend?
