Have you reprogrammed Bios?

check U28 - its U9794 in the attached scheme. Its a TPS51218 that makes the 1.1volt always on power. The system won't even begin to start without it.

On power button i have 3.3v when i press power button go to 0V.
I think NBSWON is ok ?

I need someone to fix my old bios.

NBSWON1# voltage should be available at power button but this voltage was
not available in i o controller as well. seems to be io controller failier but near
by capacitor in the same track was faulty. once I replaced it laptop work fine

Thanks for your reply. i have seen no caps burned near IO , on pin 125 EC_PWRBTN# 3.3v when i press power button goes 0V.

The only suspicious thing I've seen one caps corroded near power jack. (see pic.) i have 3.3v on it no short but i removed this caps but no change.

I think definitely is BIOS issue no?

you are sure that your bios is 8mb؟

Yes my bios is 8mb .

I mentioned on thread #4 one dump find on elvikom, its 2mb dump when i flash with him my EZP2010 show chip 2mb size , but when i flash again original dump 8mb ezp2010 show 8mb chip.
I think something is wrong with my bios chip or dump???????

Re: Pavilon G6 6050a2412801 NOt Power up

i haven't see .and haven't found up to know PAVILION G6 with 8mb
your bios of motherboard " 6050a2412801 " is 2mb .
pls . change your ic bios .and use a ic of 2mb and flash it
i can give you a working bios .

Re: Pavilon G6 6050a2412801 NOt Power up

here is your realy dump .
flash with him to use another ic as MX25L16005 ....

Thanks Ridamouh159 .Flashed with chip MX25L1605D 2mb with your dump led charge ok , but still the same problem not start.
I do not know what to do?

Re: Pavilon G6 6050a2412801 NOt Power up

Try to approach the problem from a different angle. It is not always a bios problem.
In my case, (G6-2000) changing the bios did not help either. The problem seems to be in the power system. When I press the power switch, all voltages looks to be present, but only for a brief moment, than everything is back to zero.
Remember when you touch an open system with a screwdriver by accident, the system shuts down and after reconnecting the adapter, the power is back? This fault seems to do the same.
When you have NBSWON1# 3,3V and it becomes 0V after pressing power switch it doesn't come back after you let go power switch. Only after reconnecting the adapter, the voltages are back again. Looks like somebody down the line has a short. It looks like it isn't a big short, because the power led stays on.
You can check if the voltages are present in your system and what happens after pressing the power switch. Feel the power IC for 3V/5V if he get warm when you keep the power switch pressed. In my case I gamble on the TPS51125, being the problem
Just an idea, I'm not a pro.

in my case there were no burnt mark or short on the rail .NBSWON1# no voltage
at pin 4 of power button and there were three caps in parallel .when i check impedance
of these found that one of them was not equal to other two
,removed it and replace with new one.
