Re: Laptop motherboard problem / Replacing capacitors

I was able to fix the motherboard. Thank you all!

What I actually did was from this video on youtube: [url]http://www.youtube.com/watch?v=j-Eyz0sOKR4&feature=fvw[/url] . I watched a few f them as there are plenty of them there, got the idea and it worked!

My heatgun has 3 temp. levels- 50oC, 400oC and 570oC. I used the 1st for preheating and them the 2nd but from a little bit far away as 400, according to the videos I found, was too high. If I'm right, 280-320 is the right range. And then...

Re: Laptop motherboard problem / Replacing capacitors

what does BGA stand for?
so I may try heating the memory chips w/ foil and a blowtorch? Are the video memory chips those which have a Samsung name on them? (there are 2 of them- just under the copper plate on the middle-left of the board)

I would go for it if it helped. But some calculations on the heating should be done, I think. How do I know what temperature there has to be, or how much foil should I apply on the board so as not to toast it? Is this procedure similar to Xbox's that Toasty suggested me...

Re: Laptop motherboard problem / Replacing capacitors

sorry for not responding for some time, I just was busy with other stuff



reflashing didn't work- I was not able to reflash via bios, since there is only one option to do it- I need to insert a 1.44 Floppy. I have no floppy drive in that laptop so I did it via Windows(where was an option of a windows bios setup oin hp.com). But again- no change



i think no, I haven't.




I just did it with alcohol and it gave no iprovement...

Hi everyone,

I encountered some problems with my HP nc8000 laptop:

When I switch it on, the characters are cuorrupt: e.g. instead of 'Windows' there would be 'Wondows'. The corrupt characters appear in different places of the screen when pressing buttons (or in Bios) and random colour squares appear in random places when pressing keyboard's buttons.
The screen looks very similar like written here:
