    Re: Toshiba Satellite C650 power on issue

    I had this problem from my old Satellite L series. After few times removing and installing the memory card (RAM) the card contacts tend to break the solder joints. These are fine contact leads that are soldered to the main board. You might need some special equipment to resolder the joints. I used a hot air soldering station to resolder the joints and it worked. Then I sold my laptop to a friend and so far it still works up to now. Maybe this problem of yours is just a cold solder joint on the card contacts.

      Asus Probook P5440UF-XB74 power issue
      by GLISIT
      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...

      HP Zbook 17 G6 Power Issue

      I can't figure out the power supply system on this motherboard. There's no response and no voltage readings. Here are the measurements I took at the input.

      The +VAC_IN 19V power supply from the connector goes to the three-legged transistor PQ 10009, and to the P-channel B03P03 transistors PQ10007 and PQ10006. The AC_GATE of transistors PQ10007 and PQ10006 is 6V, so the transistor is on. The VADPBL output of transistors PQ10007 and PQ10006 is 19V. This 19V then goes to transistor PQ10013, labeled
      B03P03. Its PVADPTR output is 19V, and the...

      by vettouch
      Toshiba Satellite A100-525 power indicator light disappears on pressing Power Button and voltages disappear except 4.5v on one pin of the battery terminal. Some like L9 shorts to ground and otherwise; capacitors - C340, C371, C98 short to ground, on-board and off-board. Please experts in the house, assist me pin down the fault. See schematic attached....

      Acer Spin 1 SP111-33 Power-On Issue (Troubleshooting Assistance)
      by justice171
      I am seeking guidance on an Acer Spin 1 SP111-33 that does not turn on when pressing the power button.

      Below are the observations and troubleshooting steps I have taken so far: Observations and Tests:
      1. Verified that all critical voltages are present:
        • 3.3V and 5V are always present if DC is plugged.
        • 1.8V on the BIOS chip is present.
      2. Checked the power button functionality:
        • When pressed, the voltage drops to 0V, indicating the button is functional.
      3. Inspected the flex cable connecting the USB, audio, and power button to JUB1:
        • Confirmed connectivity is intact, ruling out issues
