Re: 5.25" Internal UPS
Specs says that the better models have NiMH batteries.
There is a better thing - PSU with integrated UPS. Hopefully some of them can run the computer directly from the battery without DC->AC->DC conversion. -
Re: 5.25" Internal UPS
If those are any good, I am so buying one for my computer at work... But how the hell can it power anything but a small OEM PC with those little batteries??Comment

Re: 5.25" Internal UPS
I would only expect something of decent quality it it needed two drive bays (full height, right?) and a more user-friendly front panel like the one on my NEXXTECH UPS.Find Nedry!
Check the Vending machines!!

Hello, all.
Cyberpower Battery Backup Unit.
I bought two new ML18-12 batteries through Amazon (They have already refunded my money for the two batteries as we thought the batteries might have been bad.)
When I got them in, they were not fully charged. I connected them to the UPS and waited 24 hours before connecting any networking equipment.
In parallel, they read 24v, but within 24 hours, the meter on the front of the unit dropped from 4 to 3 bars on the battery charge indicator.
Checking the voltage, it was down to 22v.
I quickly removed everything... -
Order my parts from mobilesentrix.com and iPhone batteries have been excellent. Recently got 3x bad A1534 (2015) batteries. All would work until ~30-40+% and drop to < 10% instantly. Typical sign of cheap batteries.
Perhaps the less popular A1534 model's aftermarket batteries are more source limited. Just find it surprising quality from mobilesentrix (usually fairly high quality aftermarket parts) have been so poor.
BTW, this isn't the only defective parts I've had from mobilesentrix. Amongst others including iPad Air touch screen and A1989 touch bar (display was... -
Hi friends of electronics
What you see in the video and pictures attached is the circuit for charging the batteries of a DC motor.
The problem is that this circuit cannot charge the batteries (3 1800mAH NiMH batteries) any more. When the circuit was OK, its green LEDs lit up one at a time to show that the batteries have charged more. But now that the circuit is flawed, LEDs light up as you see in the video and at the same time successive beeps are heard.
Please help me fix this circuit.

Hi all.
I have an asus F505DV that has a smashed screen, broken hinges, bezel and top cover.
The customer cannot afford to repair it, so they wanted me to remove the top of the unit and will just use the base as a desktop and plug into a monitor via HDMI.
However, for some reason, with this model, it REFUSES to display on the external monitor unless there is also an internal LCD.
If there is a internal screen, then the external displays fine.
This is running the latest BIOS.
I have set the display properties in windows 10 using... -
Hello there,
I have a SF314-41 motherboard that i bought impulsively recently, the problem is that i only bought the motherboard only, nothing else. When i tried powering on the board with 19V (soldered on the DC IN port), and then shorting the pin 1-2 of the keyboard, the board is turning on (as indicated by the fan), however it seems like the board is displaying on the internal display as connecting to a display on the HDMI (external) does not display anything.
I tried connecting a USB keyboard, the keyboard is powered on, however pressing numlock do nothing (supposed to toggle...
