Question about Asrock ALiveNF6G-VSTA (MB-ALVNF6G) Motherboard

Sony Vaio pcg-fx140 wont boot.

This computer is 7years old but it's sentimental...
For the last month or so, my laptop has booted occasionally or will freeze and I will need to reset.  It then would take 15 to 20 tries to get it to start again.  The other day it froze when I tried to connect to a public wireless connection. I powered it off and ever since has not been able to boot. The power light is on, the fan will spin occassionally, I'm getting power to the cd rom, but the HDD light is very dim.  I have tried many things such as moving the one stick of ram to the other slot, taking the whole thing apart and putting it back together piece by piece to try to isolate the problem..  I should also tell you that the ac adapter on the board failed about the same time that this problem surfaced.  I replaced it by sodering some speaker wire and a jack to the area where the jack was. This solved my power problem but then this happened.
So the things that I am going to try now is replace the HD (Could it be that it died?) NOte...when it did start it always took me to scan disk saying there were errors...but then scan disk would freeze so I always exited out of it.
Or the motherboard?
Maybe I should buy a new RAM Module?
Or is it something else entirely?
Any help would definitely be appreciated!

    Hi KatFishGR,

    Thanks so much for your quick response!  I followed your suggestion and unfortunately the result was the same.  I unplugged, removed the battery...waited a 5 minutes.  Plugged it back in and the power light lit, hdd light lit (but very dim), heard some clicks ( I think it was the cd rom) and the fan started to spin.  The fan then stopped for a few minutes and started again this time whirring continuously.  That is the state it is in now.

    Is there anything else that it could be besides the daughter board?

    Thanks again for all your help!

    Ok. I just contacted "Geek Squad" of Best buy and they told me that it would cost more to fix then what the laptop is worth.  Gave me a quote of $700.00! 

    So, would replacing the motherboard fix my problem or is the daughterboard not included with the motherboard.  Sorry I'm a little unfamiliar with what the motherboard consists of and I don't want to waste my money on something if I don't need to.

    Ebay is selling a refurbished one for $50.00 + shipping.

    Oh and I gave you an almost

    I need your help again. I ended up buying the board, installed it, and now all 3 lights come on and then turn off within seconds. Is there a jumper switch on the motherboard? If so, where would I go about finding it?

    any help will definitely be appreciated.

Hi I noticed your solution to a sony power fx series problem. I think i have the same problem, i replaced the charging board (bought one from ebay and it worked for about 2hrs then i got the same thing again, the cpu fan would turn on for a split second and so would the lights. You mentioned in your solution about a cpu daughter board? I don't have one in mine (just a socket), or are you talking about the charging board, as its the only seperate board thats connected to the motherboard.
Where are these caps that you are talking about are they on the charging board or the motherboard? unfortunately i can not sink much more money into this system, but i can spend a few bucks replacing the caps (yes i know they are surface mount). Any help would be appreciated, i have a fx-140, i just spent 60$ for a wireless card and memory upgrades and i get everything install and then that happens...very frustrating.

Here's some interesting info for you.

Alot of the FX series Vaio's from years back started to suffer from similar power issues. They slowly get worse over time. And eventually, the thing won't run longer than a few seconds if at all.

If you remove the battery and the power cord, let it sit for a few minutes, and then plug back up, does it come on for a brief period??

The most common issue with the FX series, was the CPU daughter board. There are 11 surface mounted capacitors that need to be replaced. These would fail over time, usually due to insufficient cooling. And cause the laptop to sense a false high temp reading from the cpu. The laptop would shut off prematurely. Replacing the caps solved the problem for most. Or simply replacing the CPU daughter board.

I have repaired several of these at my shop in past years. But if you would like to research it yourself, just go to and do some searching.

    No, thats more than likely going to be your problem. The fact that the fan runs the way it does is a pretty good hint that those capacitors or the whole cpu daughter board will need to be replaced... getting a false high temp reading when powered on.... quite common with these. That is the only solution. I could repair this problem if I had it here. An "almost there" vote would have been nice... :-) As there is most likely your issue.

    I saw this same board on ebay for 49 bux as well... thats a pretty good deal if you ask me :-) id go that route and be done with it... seeing as you had a power jack problem as well, this would also put that back the way its supposed to be. Thats a pretty good price for a used board.
