FAST MODE vs NORMAL MODE
I have recently acquired a HP 6632A DC power supply. I am just beginning to use it and I have been reading the manuals for it. It is the first power supply I have ever owned or used. I am a very beginner hobbyist and do not have an engineering background, as may be obvious by my question...
I can't seem to understand what the actual use is for the 'Fast Mode' or the 'Normal Mode' on the power supply. Although the manual states what the two modes do from a engineering/technical standpoint, I don't know enough to understand what it all means,... -
Hi everyone,
I’m working on a Denon AVR-X4000 that goes into protection mode (fast red blinking LED) shortly after the second relay click.
According to the service manual, a fast red blinking LED indicates a DC detection (DC_DET) or ASO (abnormal current) fault, meaning the unit is detecting a potentially dangerous condition on the power amp or power supply side.
Here’s what I’ve done so far:- Fully opened and cleaned the unit (a lot of dust inside)
- Removed and visually inspected the AMP board → nothing visibly damaged or burned
- Testing is done with

Hi friends.
I see there are many clever people here.
I purchased used Note 10 plus phone,and it doesn't have good battery cuz it's been used probably more then a year.
Since I'm not an expert into phones but my own thought is that fast charging with high current wears out battery more quickly and damages cells compared to regular charging.
I don't need fast charging at all so I disabled that option in phone,since I don't care if my phone will charge 1h or 2.5 h (with regular charging).
But want to ask does fast charging damage the battery cells as time passes... -
hp Pavilion 14 CE-1XXX
MB G7AD-2G DAG7ADMB8D0 REV D
Processor i5 8265U
AFAIK schematics or boardview are not available for this MB, but I used a similar board as a reference (G7AL-2G)
Laptop came in not booting with caps lock blinking 3 fast- 2 slow indicating RAM error. Charging works fine. Found bad soldering on the only ram socket present (2 outer left pins and 2 outer right pins).
Once soldered the laptop started fine and I was able to install Windows 11, upgrade BIOS to version F30 from Windows without a problem, BUT I found a strange and annoying...
