Hello, I've had a problem with this laptop for a while. I've replaced the motherboard after it died, and it was seemingly working fine after, but it stopped powering on after I shut it down. if I remove the battery connector and plug it back in, it will boot fine, but if I shut it down again it will not power up after that until I unplug and replug the battery in. When I press the power button the caps lock light will light for half a second but will not boot. I've tried replacing the RAM and the battery but still the same issue. The only thing I've found to get it to turn on consistently was taking out the battery, plugging in the charger and booting it on AC power. Even then though, I still have to disconnect the AC power from it after I shut it down to get it to turn back on, or else it will just not power up. Any ideas? I was thinking maybe update the BIOS but I'm not certain. Thank you

Hi all,
TL;DR - this laptop is driving me nuts with the oddball power-related behaviors. Appreciate any insight you can provide!
I'm experiencing a power issue on an Asus Probook P5440UF-XB74. Although I've worked with electronics and computers for decades, this is my first attempt at getting into motherboard-level component troubleshooting. Any help the community can provide is greatly appreciated!
A few weeks ago I was using the laptop (on battery power) for a Zoom meeting. The battery was running very low (long meeting) but I wasn't worried about... -
Hello,
I have a problem with an Asus X553MA motherboard. Sometimes the system works fine, but other times the CPU voltage drops to 0V. In most cases, the laptop reboots after a few seconds due to the voltage drop.
Occasionally, it shows the ASUS logo or boots into the BIOS. Sometimes it can stay in the BIOS for hours without issue.
I checked the board with a thermal camera, but I couldn't find any overheating or leaking capacitors.
Unfortunately, I don’t have access to the schematic.
It seems to me that when I bend the board, something changes.

Hi everyone,
I'm having a serious issue with my ASUS Zephyrus GA401I (4 years old, worked perfectly until recently). The system is lagging heavily, even in the BIOS, and is charging extremely slowly (a few percent in hours), making it nearly unusable. I suspect a motherboard or power delivery issue.
Symptoms:- Severe lag across the system, including BIOS navigation.
- Slow boot times and unresponsive performance in Windows.
- Battery charges very slowly (e.g., ~5% in 2–3 hours).
- No error messages or BSODs, just extreme sluggishness.
What I've Tried:- Replaced

Hello everyone,
Mark and model: ASUS X571
Symptoms: not turning on. There is only the LED battery indicator working. The owner of the laptop told me this problem arrived one week after having changed the battery. He then managed to power on the laptop only once, and then it never powered on again.
Tests already made:
- Battery is charging when laptop is plugged in. The LED battery indicator turns white after a couple of hours of charge, indicating that battery is fully charged. However, laptop won't turn on anyway, with or without AC plug.
- I have removed... -
Hello
The PC starts and shuts down correctly when the battery is removed. However, if I hot-plug the battery, it starts charging as if everything is normal. However, when I turn off the computer and then restart it, there is no display on the screen. The battery indicator blinks slowly, the fan runs, and the power consumption is approximately 520 mA, as if the computer is in standby mode. At this point, even if I disconnect the power supply, the computer doesn't start up normally anymore. Pressing the power button to force a shutdown works, but as soon as I release the button, the...
