Hi! I have an hp 840 g3 when I turn off the machine apart from the power LED all the other LEDs stay on and the fan continues to turn and the machine is turned off too.
Can anyone help me thanks in advance!

You mean fan still spinning after shutting down from windows? If yes,then solution is provided on many occassions in this forum.
01.Remove wifi card
02.De-solder sound/lan /card reader chip
03.Replace dc-dc converter for 3v/5v
Most likely its the dc-dc controller which is broken.

OK, this is a long shot. I got this sewing machine cheap because it's end of line, ex-display, and had no pedal. The genuine pedal costs £60, while Ebay knock-offs go for around £15. So I went for the knock-off, it doesn't work, and I'm not sure whether it's the pedal or the sewing machine that has the problem.
Now this is an electronic machine, unlike the old fashioned sort where the pedal was a big resistor in series with the power to the motor. Here, the pedal is just (I think) a variable resistor fed with a 5 volt supply, and limited to a current of 5 milliamps. Assuming that... -
Hi everyone,
I am trying to fix a samsung washinmachine power supply main board.
I already replaced it with another one to fix the machine but i want to try understand the issue with the old board.
Therefore i hope to be able to get some help to explain what to check in order to troubleshoot.
The power supply board reference is the following: DC41-00189a
I have followed one thread (https://www.badcaps.net/forum/troubl...ingmachine-rel... -
Hello there everybody, I'm not sure if it's the right topic to ask this but I hope so.
I have a CNC machine wired to 3-phase 230V AC.
It's a smaller CNC machine with a 3500W motor, do it does not uses much power.
The problem is, when the residents come home and put load on the network, the voltage can drop to around 207V which is fine for most household items but by CNC machine stops working from this.
I contacted the electricity company but they refuse to help me solve this problem.
So I started to look around for some DIY... -
Hi all,
I got a 820-01700 of a friend that doesn't turn on. I read that a typical issue with these boards is the TPS62180 generating the NAND voltages, so this is where I started looking. Sure enough, PP2V5_NAND_SSD0 is 4V when the machine tries to turn on (I try to determine this by measuring PP2V5_NAND_SSD1, which is 2.5V as it should in this case. The PP0V9_SSD0 and PP1V8_SSD0 power supplies for the SSD are on at the same time when PP2V5_NAND_SSD0 is 4V). The extremely weird thing is that when the machine is off (PP2V5_NAND_SSD1=0, PP0V9_SSD0=0 and PP1V8_SSD0=0), PP2V5_NAND_SSD0...
