Took another look at those R2496, R2499, R2501 and they seem to be working just fine.Leave a comment:

No power when measuring those. I will try to take a closer look at them.Leave a comment:

Re: Sony vaio vpcy2 mbx-229 completely dead
I think I found those even though they are unmarked. One is 500 ohms and two of them seem to be dead. One of the dead ones has 19 V on other side and 0.5 V on other.Leave a comment:

In U121 pin4 is 19 V and pin 5 is 0.5 V.
Resistance from U119 pins 5-8 is 410.Leave a comment:

No. Pins 5-8 have only 0.01 V. Pins 1-4 have 19.Leave a comment:

Re: Sony vaio vpcy2 mbx-229 completely dead
Can anyone explain to me how are those 3.3 V and 5 V generated and where.
And also is that BATOUT voltage supposed to be 0.01 V?Leave a comment:

Been trying to make sense of those schematics but no luck with that. So I could use some more ideas on what to try next.Leave a comment:

Sony vaio vpcy2 mbx-229 completely dead
Hi
I have this vaio vpcy2 which has no signs of life. No lights, no response to buttons, no charging, nothing. And no visible damage.
Plugged in or battery makes no difference.
Mainboard mbx-229 has 19,50 V on connector when plugged in.
Any ideas what might be the problem here? Or what to check next? -
