I have try with 3 different adapter

Dell adapter 40w - warning "Slow Charger" (charge rate 8mW)
Dell adapter 65w - warning "Slow Charger" (charge rate 8mW)

i already tried update bios and update all driver but problem still persist....any idea to solve this?...

Hi friends,

I recently acquired an old PC power supply (along with several vintage motherboards from late 90s/early 2000s). The PSU was dead upon first test, but quickly identified the internal fuse had blown. I fixed that, re-tested and i'm pleased to report it seemed to work great after that - no obvious issues or reasons for the fuse to blow.

Afterwards, I inspected the capacitors more closely and noticed one pair required replacement. They weren't in bad shape by any stretch of imagination, but one was slightly bulged, and I wanted to swap them out for good measure....

Board powers on, holds charge it seems, track pad clicks, display is working etc. When trying to boot it turns itself off and then boots again and repeats. If it stays at GLOBE icon it will not turn off. Customer needs data, enabled THUNDERBOLT Mode, plugged in Thunderbolt cable, but error comes "THIS DISK CANNONT BE UNLOCKED DUE TO AN ERROR" I can't even input a password.

Hi Guys,

Weird one here. I have a special GPU made by DFI (Model LS3440) from an Arcade gaming machine. The GPU uses the S3 440 GTX Chipset, and has dual DVI-I ports. For some reason, the analogue has stopped working on both outputs (DVI-I to VGA cable). DVI-D and digital outputs work fine, just the analogue that has stopped working.

Now, I could get around this by using Active cables to convert the signal over to Digital, but its got me wondering exactly what the issue could be. I have inspected the GPU and DVI ports under my microscope, but nothing stands out. Because...

Recently acquired one of those silly Logisys acrylic power supplies and lucked into getting one of the "better" ones (most of an input filter, bridge rectifier instead of 4 diode treatment, OK-sized heatsinks, etc.) and wanted to fill out what I can on the board + get some decent caps on there (especially the primary side since I highly doubt the ones in there are actually 1000uf). My questions are:

1. How do I know what components to install re: the input filter? It seem to be missing an X cap, a resistor, and a Y cap.
2. Where can I find a good heatsink for the bridge...

Hi house,

I have an HP elitebook 745 g3 with no power, I've checked the board for shorts but can't find any

3v and 5v aren't present either, 20v is also not present pin ACp and ACn of the charging IC

q1304 has 20v on one end and only 4.7v on the other end, meanwhile on another similar board 20v is present on both sides of q1304

I've reprogrammed the BIOS, changed the charging IC and still no luck with getting the system to turn on

[survivalbloke]

This laptop came in for no power. I saw the board was not taking any power so I pulled the board and began testing. As you see in the photo, on those pair of mosfets, I had 20v into and out of mosfet 1 and 20v into mosfet 2, but only 3v out of mosfet 2. I found a location which was shorted and injected 1v5a and it took all the current, but nothing is heating up with the thermal camera and I can't for the life of me figure out how 5a isn't showing on thermal.

I have a a2337 m1 MacBook Air that has no power.
PP5V_BSTLQ_SPMU is shorted so I fix it by change cap, coil, u7700. now normal voltage.

when I didn't connect battery , plugged in power, there is only 5V 0.25a.
so I checked every power rails , I finally founded PP5v_s2 is 0v, but there is no short.
PPBUS_5VS2_VIN = 12V normal
P5VS2_EN from U8100 = 0.6V maybe normal

P5VS2_FB,PGOOD,VC,SS,BIAS,INTVCC = very low voltage maybe abnormal.

what should I do ?? do I need to change uc300?

Dear Badcaps forum members,

Hope that you are all well!
I am a newbie on a mission to figure out the cause of the PSU making a "chirping" noise:


Having searched for this symptom online I have found [URL="https://electronics.stackexchange.com/questions/447966/switching-power-supply-chirping-how-to-fix"]some indication [/URL]that failed capacitors may be an issue. To help with the troubleshooting, I have tried to isolate the problem and disconnected the PSU from the rest of the device - the chirping remained.
I have then found that...

Hello members of the repair forum,

I'm facing an issue with my MacBook A1989, where I encountered a short circuit on PP1V8_G3S for reasons unknown. After removing the audio amplifier and MIC, the resistance values returned to normal.

However, during testing, I found that attempting to enable Bluetooth yields no response. Bluetooth cannot be activated, and the PP1V8_G3S-to-ground resistance value is approximately 285. I suspect that PP1V8_G3S_WLANBT_VDDIO may, under certain conditions, exceed 1.8v, potentially causing damage to the Bluetooth module. I am considering replacing...

Hello, I have a setup with NVR 16 Canais H.265 1080p HD PoE+ - TRENDnet TV-NVR416 that is using 10 cameras, some are outdoors. What would be the best way to protect NVR device from power surges? All ports are PoE so the NVR supply power to the cameras. NVR is pretty expensive so I would like to protect it somehow. Should I use some kind of switch that needs to be connected to the cameras, so it could "take a hit" if there is a power surge. Thank you!

No Boot, No Post, 3 red 4 white. No measured shorts or visible issues on board.

Known good cpu and ram.

I have attached the main 32mb bios, and 16mb rom dump. I suspect, either a rom or EC or PCH issue - the PCH under thermal does seem to be quite active, but might just be confused by something coming from the EC. (Not sure if it has something to do with top swap strap (TS), sampled...

I am trying to troubleshoot my 2018 Mac Mini. It all of a sudden would not respond/wake up. So i turned it off and turned it back on. When I power it up, the fan blasts hard for a second, then shuts off, power light may go off, then back on, sometimes blasting the fan again. It does this a few times then eventually(sometimes) the power light stays on and the fan runs at a normal speed, but with no HDMI/display. Nothing ever shows up on the display.(no sound, no chime, checked wifi router to see if it trys to connect, which it does not)

I have a MacBook Pro A1502 with no power.

180-200mA without battery, 1500mA with battery, and orange light on the charger.




Short facts:

*USB with LED lights up.

*No fan spin.

*Adapter sense and sys_onewire is ”only” 2.861V.




I checked the DC board as well and the adapter sense is 2.861 V, I'm not sure if it's too low

That's why I'm asking you guys for help.
