DEVICE: Laptop
Model: lenovo thiinkpad t410
Board Id: 09A33-3 48.4FZ09.031
NZM1H-8
ISSUE: NO POWER

From the first mosfet 20v is not passing through, pin 4 has 19.5v and the first mosfet is a P-CHANNEL mosfet (SI7121DN) i think the pin 4 should be lower to active the 1st mosfet to allow the 20v to pass to second mosfet ive check all for shorting in the board , i did;nt find in rails, so ive check the schematic and im suspecting that, my Q61 is faulty due to its pin 1 is 0.47ohms? im not pretty sure, hope someone can help me figure out this issue.

Good day!
I have a customer's laptop — Acer Nitro 5 AN515-54 (EH5VF - LA-H501P). It has a display on the external monitor and it's working fine, but the issue is NO display on the internal screen. I already replaced the eDP cable and checked the LCD connector pins.

Here are the voltage readings:

• Input – 19V (stable)
• +LCDVDD – 3.3V briefly, then drops to 0V
• EDP_HPD – 3.3V briefly, then drops to 0V
• PCH_BKL_PWM – 2.2–5V briefly, then drops to 0V
• EC BKOFF# – 1.8V briefly, then drops to 0V
• PANEL_OD_EN – 0.3V

Is it possible that the EC chip is corrupted or damag...

This power supply is 30v 5amp. Problem is when turned on after about 3 minutes voltage starting to decrease slowly. (like - 5.8 > 5.7 > 5.6 > 5.5) can't see any damaged component or dry solder joints. Checked main 2 transistors with multimeter. Reading seems ok. Tried changing potentiometers(both coarse and fine) still the same situation. Can any one help me to troubleshoot? What voltages to check? Any ideas helps to fix this. thank you.!
