flash another bios, not the read one..get it from the site or read from another working unit. -
i have almost same problem, but for me i replaced another t2 chip instead of i reballed it...try to replace a new one againLeave a comment:

i have the same problem for that kind of msi GPU problem., i replaced the GPU. then its done.Leave a comment:

Thank you to all for the help, specially to Dcortest for the Boardview that really solve the circuit. i change the 2 mosfets that are P-mosfet and N-mostfet connected to the line of Charging IC....

here is the Readings of the DCIN mosfets before the Current Sensing resistor
the first dcin mosfet measure by resistance mode:
[B]source/drain 8.8Mohms[/B] (probe RED BLK)
[B]source/gate 1.3Mohms [/B](probe RED / BLK)
[B]gate/drain 14.34Mohms [/B](probe RED / BLK)
the 2nd DCIN mosfet measure:
[B]source/drain 7.8Mohms[/B] (probe RED BLK)
[B]source/gate 1.3Mohms [/B](probe RED / BLK)
[B]gate/drain 14.17Mohms [/B](probe RED / BLK)here is the Readings of the DCIN mosfets before the Current Sensing resistor
the first dcin mosfetLeave a comment:

this time trying to test all mosfets and capacitors that is shorted...motherboards seems so clean no sign of burnt or bad components...still checking this time.

i try to read the resistance to ground on Current sensing resistor is 20Mohms, seems to be good....Leave a comment:

Both DC-in MOSFET first and second got high resistance ranging Kohms to Mohms when reading for source/gate ; gate/drain. no low resistance got from this side and around the Charging ic mosfets.....Leave a comment:

thank you for the very fast reply..i will test today what you mention. i will update later today....Leave a comment:

ASUS FX507v No Power
I have ASUS laptop FX507 when i plug-in the charger nothing happens or the amperes not even raising up it stays to 19.5v(SETTINGS). I decided to disassemble the back case to check the voltages first. I found out that when i test the current sensing resistor for voltage it was fluctuating voltages(3volts to 5v then loop), i checked the voltages of the BQ24800 Battery Charge Controller:..i started with the pin 1 and the results are:
1. 3.5v to 3.9v
2. 3.5v-3.9v
3. 0.3v-1.4v
4. 0.3v-1.2v
5. 0v
6. 2.6v
7. 0v
8. 0v
9. 1.6v
10. 0v

some can read and write, but the new chipset ICs might not. usually we use SVOD programmer...Leave a comment:

Check also the lid sensor at the back of your display connector which is U24 that gives +3valw and backlight onLeave a comment:

I had the same problem on my Getac, it's caused by a faulty magnetic sensor which causes the laptop to think it is always closed.
In this state, the screen brightness goes down to minimum and the CPU frequency is locked at 0.4GHz. Luckily it is possible to disable the magnetic sensor in the BIOS on those laptops so you can use it normally.
The only downside is that the laptop won't go to sleep automatically anymore after closing the lid.

The failed verification can turn off in settings to bypass verification. do you have bin file that came from original mb...Leave a comment:
