HELLO, any one have boardview or schematic for this LA-L663P??

OH..i figure it out without the boardview. there is a fuse behind the motherboard. thank youLeave a comment:

sony vaio VJS112C11W FAN NOT WORKING
I tried to check and look for the Boardview and schematic for this Sony Vaio with mb marking DA0MSAMBAG0, the problem of this sony is the fan not working or spinning, i checked the 5volts to red and yellow, black zero volts and white zero volts. i checked the fan and test to direct 4volts it is spinning. Any diagram to trace this fan not spinning. i change the new fan still not work. Any one have a boardview and schematic diagram?...

DELL INSIPRON 14 No power blinking orange/white
i have DELL INSIPRON 14 5410 2-IN-1 blinking orange and white when charger connected, i tried to find Boardview or schematics but cannot find. i opened the unit and the motherboard model number is 203071-1 Watchmen that i found written on motherboard. Where should i start because when i press power on, nothing happens. but i checked the main power rails voltages are enabled and the charging for battery LDO is 3.3 volts.

Hi all, where can i get the Schematic and boardview for this [B]iPad Air 4th Generation A2316,[/B] or where can i have my subscrition? i really need this. Thank you for the answers.

flash another bios, not the read one..get it from the site or read from another working unit.Leave a comment:

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:
