Windows 10: Android Phone keep charging and VGA lamp keep On even my pc is Shut Down in Windows 10 64-bit

Hello Sir, Madam or anyone, i want to ask


I shut down Windows 10 April 2018 Update on my PC using ALT F4, Then select shut down, then OK. Even my PC is Shut down (Without getting windows ready, etc), i can keep Charge my Samsung J1 Ace Android Phone when i plugged My phone using usb cable from the CPU usb port. And also, my VGA lamp is on even my pc is shut down.. is that a bug, and why this is hapenning. Sorry my english is bad


Motherboard : ASUS M5A99X EVO

GPU-Z update loop (Windows 10 64-bit)

I don't have better steps - this is all, I have nothing to add.

Maybe it is worth noting issue was on Windows 10 Enterprise, build 14393.187, so maybe you should test on the same.
My other PCs have a different Windows 10 version - Pro, latest Insider Preview build from last week, and there is no such issue on those.
All are 64-bit edition of Windows 10.

This issue is not new. I have had same 1-2 years ago too, with older GPU-Z versions.

EDIT: And yes, I have Windows 10 UAC enabled and set to defaults. If you are using your Windows PCs with UAC off, you likely cannot reproduce this issue. *Smile

 

$.10 android apps

Not sure if anyone's seen this yet, but they have $.10 (yes, 10 cents) android apps on the Android Market to celebrate 10 BILLION downloads. So far I've picked up Tetris, Need for Speed Shift, SoundHound amd ADWLauncher EX. There were several other games that were listed, including ones too good for my phone *Frown

 

Charging Lamp

Ok, so it is not a casemod, but casemods are kinda boring...

I have decided to make something cool and practical at the same time.

Pretty recently I have purchased this desk lamp. It looks very cool for a less than $8 dollar item, but it also has some space at the base of it, so I immediately thought of putting something inside *Eek!

*42970-7ce06bb8fbd0ed653b8b2aa60af1c09e.jpg* *43009-a269d967f604b238b566169cf0fca0cc.jpg* *43008-23e3a482aa8530d511780915117c0442.jpg*

Also I suffer from insufficiency of space in my office, and because of that there is no elegant or even practical way to charge my phone anywhere near my desk. So I've decided to fix this problem by incorporating the universal USB charger (5W) into the base of my lamp. This way I can receive phone calls without the need to run to another room.

The main idea is:
- Disassemble the lamp
- Disassemble the phone charger
- Make an incision in the lamp's base, to have access to USB plug
- Mount charger's PCB inside the lamp and solder it's inputs to lamp's input

So far i found a 35V AC converter inside the lamp. Soldering is very flimsy, so the first thing I have to do is fix it(DONE). Also this gives me the possibility to spare my charger and make an "extension" of the built-in PSU.

I have found the perfect 5W PSU on dealextreme. Also they provide female USB connectors, that i require for this project. It is small enough to fit into the base of the lamp and I can solder it to the input V~, bypassing the problem with the power switch.

So, lets begin ...
TOOLS AND PARTS
[*] 5W Switching Power Supply
[*] 74.4K , 49.3K , 49.7K and 42.5K Resistors
[*] USB Female Connector
[*] Soldering Iron
[*] Some insulated copper wire
[*] Scisors
[*] Multimeter
[*] Victim-phone w/ USB cable





First things first. Let's figure out how USB charger works.
Of course you need 5V DC to supply power to your device. This will be provided by our Power Supply.
Also we need to tell our phone/tablet that it is connected to the proper charging device. For this purpose we have to build a bridge to supply needed voltage to data connectors of our USB connector.
Here is a pinout for 5W USB charger and a scheme of the bridge:






Of course with my luck I had no such resistors, so I had to replace the whole thing with theoretical equivalent, that outputs 2.043V and 2.755V (which is pretty close to what we need).
These are pretty much all the parts and tools we need.

Once the bridge is put together and soldered to the PSU, we have a working prototype:
*46787-4566f5e1d69eb23c6ed07e549835660c.jpg*
The initial testing showed that even with slight difference of resistance on data pins charger was able to push close to 850mA. A complete charging cycle took about the same as from the original HTC charger.

This is what my lamp looks like with USB port installed:

And the final result with Arduino Nano plugged in:

P.S. It's been a while since I've "abandoned" this thread, but it's mostly due to busy work schedule.
Lamp was finished almost 3 months ago and I've been using it ever since then. It became not only a cool charger that you can surprise(or completely weird-out) someone with, but also a useful workbench PSU for almost all of my small USB-powered devices.
