      by Victor Moreira Silva
      Hello everyone,

      I'm trying to repair my old Acer Nitro 5 (AN517-54-55T5). I've already bought a new laptop, so this is more of a learning project. For the experience, with no high expectations of success.

      Well, my decice specs are the following:

      Model: Acer Nitro 5 AN517-54-55T5
      CPU: Intel Core i5-11400H
      GPU: NVIDIA GeForce GTX 1650
      Motherboard: GH51G LA-L181P Rev:1c

      The symptom:
      When pressing the power button, the power LED lights up for about 5 seconds and then turns off. Initially, the issue was intermittent: sometimes...

      Acer Aspire 5 A514-55 - won't power on, no charger LED, battery not flat - usual suspects?
      by DenK
      Dear all, I am trying to troubleshoot an Acer Aspire 5 A514-55 that won't power on. I'll describe the symptoms and my findings so far, and I would like to seek guidance and suggestions on possible suspects in terms of cause/component failure.

      Desoldering gun station modified to use a 18 volt @ 20 amp switching power supply
      by sam_sam_sam
      I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump

      One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy...
