Re: Sony VPCF24L1E schematic

That isn't MOSFET seat? The piece that blew up

Don't think so, the markings next to it are PC221 and PC277 and I cann't see them being in another position.
Thanks for our reaction though.

Re: Sony VPCF24L1E schematic

Q!
what does it do now? the notebook?
no power? no display?

Is does do nothing at all. nothing lights up. Totally dead.
I checked all of the fuses, nothing there.
Put back one of the C's, other pictures on the net showing one C only.

Checked the application doc from the BQ24753 , typical system schematic and I see 4 mosfets, Q1 and Q2 are ACfets, Q3 is BATfet and Q4 is on the HIDRV.

On the mobo I see only the 2 pcs, Q1 and Q2, But what is there function?
and which one are they in the application doc?
If they are the Q1 and Q2 ACfets, they have the 19,60V on drain and source and the gate gets 13,31V so it is open, but is the 13,3V not too high?

ACDRV and BARDRV do not change when you plug in the battery.

I am bussy trying to understand the doc and the meaning of the signals and that way get to understand the functions.
Thanks for your patience.

Re: Sony VPCF24L1E schematic

we need to find where is 3.3 and 5 v generated.
find other chips so we can find the datasheet cuz there is no schematic for this piss of %$£" motherboard.
not only qfn; all of them

Given already a few I could find in previous message.
Chips on the board:
W83L604G (winbond) smbus-gpio
NPCE791LA0DX (Nuovon) PCH
VT1316MAFA (Volterra) QFN
D720200 (?) PCI-USB3.0
BQ 24753A (TI) Charger, checked already
RTL8111E (Realtek) eternet ctrl
ALC275S (Realtek) soundchip?

could not find all of the datasheets yet

Cant you google a photo of that board n find out?

That was the first thing I did and found out that not both C's are always present. So I put back only one

Re: Sony VPCF24L1E schematic

Use the schematics of MBX-215 (as recommended). Most circuits are the same.
Start by checking main cois for resistance to ground. Take hi res picture of both sides of the board so anybody can read the markings of the smd's on the board.

Thanks dfor your reaction.
The pictures is the best res my camera can do.
I tried using the MBX-215 schematic but the first 2 C's where I was looking for did not exist. I will try for the other components.

After many many hours on the net, I found the block schematic from the MBX-243. The correct one out of the SM from the VPCE24

Values SN608098 sys power +3_3V/5V

pin 3-0,2
pin 19 0,45

pin 17 - 0,3
pin 7 - 0,45
pin 13 - 0,11
pin 20 - 0,45
pin 4 - 14,06

all others 0V

I used the schematics from the M931 MBX-215

Re: Sony VPCF24L1E schematic

As you can see you got short on L3 and L4043. According to the MBX-215 schematic are on the 3vrun line.
On 3.3v/5v regulator you give some values and you mention that the rest are 0v. In order to have those values you need 19v on pin 6 ???????????
Pin 4 14,06v ??????

You can check the shorted line by suppling 1v-0.2 amp on either L3 or L4043 and slowly increasing the amps (do not exceed the 1v because you are not sure this is 3v line).
You can check what is getting hot. The best way is a digital thermometer with a thin thermocouple (like the omega one's) which have quick responce.

[hansie55]

Re: Sony VPCF24L1E schematic

Checked again and I do not have 19V on pin 6. Max is 0,5V
Pi 4 is really 14,06V.
For the other values typing them is useless, because all of them are very low or 0V
This is all very strange, where did the 19V go and where does the 14V come from?

I will check the shorts and get back to you with the findings

Re: Sony VPCF24L1E schematic

Guys, I'm sorry but I misunderstood something.
DJ_ricoh asked me if I could inject voltage and I said yes, because I thought on a fixed power supply or adapter.
The instruction from Atsio make me see it has to be a Lab power supply, which I don't have.
So I have to check the entire 3V rail for wrong components by hand.
That wil take a while and I need to look for the schematics

Re: Sony VPCF24L1E schematic

Hi Guys,
I am still fighting with the board and ran in to something.

On pin 6 from U16(SN608098) suppose to be Vin = 19V, but I have only 0,6V.
When I folow the traces, opposite pin 6 I find a C, not connected.
From there it goes to the other side to PR208, Which seems to measure over 100MOhm.
To me it looks to high, but on both sides I meassure 0,6V.

According to the MBX215 schematic, the Vin is decoupled by a C and with a resitor from 0 ohm connected
to DCBATOUT, which is 19V?

Today,while handling the board, I suddenly missed PR208. Completely of the board.
The traces on both soldering points looked very bad coroded with something, so it was never good connected
and thats why I measured above 100M.
I put a correct PR208 and have 19v ON PIN 6 AGAIN.
Regretfully it does not work yet, but a couple of values changed.

pin 1 - 1.93
pin 3 - 1,09
pin 4 - 14,06
pin 5 - 3.64
pin 6 - 19,60
pin 7 - 0,45
pin 13 - 0,11
pin 17 - 0,3
pin 19 - 0,45
pin 20 - 0,45
pin 29 - 1,93
pin 32 - 1,02

all others pins - 0V

There is something else I do not understand.
Oposite and connected to pin 2 of U16 is a small resister that measures as a short to gnd.
In the schematics of the mbx-215 page 47, pin 2 is connected to system vcc and via pr121 connected to agnd
pr121 is 0 ohm. what is the meaning. It looks like a straight short.?
