there is no datasheet for G5388K11U but I found a direct replacement APW8861, APW8861QBI, APW8861QBI-TRG datasheet is available...

try also to take photos of the motherboard and place the measured voltages of the coils, also the 19v rails. maybe you are missing a 19volts rails. do a resistance check from ground to any coil that you can access make sure there is no short circuit I mean is dead short. sometimes 1 ohm or 5 ohms is ok it depends on the board design.Last edited by Duranitron; 04-30-2025, 12:45 AM.Leave a comment:

Hello, when it starts does it continues to run? or it hangs or turn off? try to run the unit with adapter inserted and with battery only, try to use known good adapter. If you can access the motherboard try to measure the always on voltage usually its a 5v or 3.3volts that is always on. it waits for the turn on button to be press to wake the unit. any beep code or cpu fan spin? try also to swap good ddr memory or clean the pins, try to measure the voltage on all coils that you can find in the board and post it here, do this at your own risk....Leave a comment:

So Bios is ok. 5v and 3.3v rail ok..and you can turn on and off the laptop with all the main voltage present. the processor warm up when on. The only problem is the display is blank, no video on external monitor. visual inspection first top and botton of the mobo and then try to run the system with bare minimum. try to power the motherboard only and place an external monitor to isolate it from the rest. try to boot it. make sure to place the heatsink and fan as AMD is known to heat up fast. Maybe an attachment is malfunctioning.. the LVDS cable is shorting or maybe the battery or wifi card. a...Leave a comment:

I recently got hold of this laptop [B]Fujitsu Lifebook E558.
Symptoms: S[/B]ometimes its ok, Sometime it hangs the system, sudden bump can cause the hang specially if you are using the HDMI as monitor, I am puzzled about the problem of this Laptop. erratic behavior of the usb, audio jack, lan port and HDMI port. and came across your thread maybe it my lucky day..😀😁😁😁
Thanks for the info its really a time saver and really solved the problem.
(the connector and cable really looks sturdy and doesn't suspect it to being the culprit) and planning to buy the daughter...Last edited by Duranitron; 11-30-2024, 10:00 PM.Leave a comment:

Many Moderators here can determine either your bios is at fault. Just post the bios here to make sure that the bios is not faulty. all your voltage rail is normal. They can clear the ME region of your bios. Try that first before you jump in to the advance stageLast edited by Duranitron; 11-30-2024, 10:30 AM.Leave a comment:

Have you saved the original bios of your unit? Supply the original bios of your model and post it here include the model # the serial number# or service tag serial number, many of the generous and kind hearted people here will to the rest... 😊😊😊 Try to flash the bios with clean ME...Last edited by Duranitron; 11-29-2024, 08:11 PM.Leave a comment:

Thanks for the reply. I already turned on the unit by shorting the pin 25 of the keyboard connector.. only the 5v and 3v coil voltage is not present. There is no short in the 3.3v rail but I measure 1 ohm resistance from coil to ground. I remove the soldered joint that connect the 3.3v rail to the 3.3v coil to isolate the 3.3v supply to the circuit. The 3.3v power supply is rated at about 10 to 30A , I think the problem is in the 3.3v supply. Removed the shorted mosfet PQ8703 and replaced it with new again.. power it up.. then the mosfet PQ8702 shorts but not he PQ8703.. Investigating if this...Leave a comment:
