Hi to all, i have 2 of those motherboard, same model, same revision, the first one had BIOS corruption and is now working, the other one had BIOS corruption and I programmed them, motherboard starts but I only get 00 error on the 2 digit display, I have all the voltages OK and have tried with the bios chip from the working one, with same result. I have revised the socket and all the pins holes seems OK, If I put the oscilloscope in the BIOS chip I get no communication, just a straight line.
What can I look now?
I want to know if the BIOS chip should send in the pin 2...Today, 06:16 AM -

I have a 5W lamp on 12Volts battery, I want it to be half as bright, so I will add a resistor. What resistor should I supply?
A = W = 5 = 0.416mA
_ _
V 12
R = V = 12 = 28.84 Ohms (R) this is resistance of lamp
_ _____
I 0.416
So I will add one resistor 28.84 Ohms
I will have 28.84 + 28.84 = 57.6 Ohms
Or 28.84 + 28.84 = 14.42 Ohms
I don't know if it will work in series or in parallel
voltage would be 6V and amp current mA = 0.208mA We divide everything by two

Hi all,
Model: HP Pavilion 14-ce3010nh 8BV97EA
Board number: DAG7ALMB8C0 - G7AL REV C
Issue: I have an HP Pavilion 14-ce3010nh 8BV97EA laptop. When plugged into the charger, it turns on, but there is no display, the fans do not run, and the processor gets slightly warm. Unfortunately, I haven't been able to figure out what the problem is. I've reflashed the BIOS twice without any success. No post. Already tried out with another ram stick with no luck
I measured the voltage with the HP turned on in red, and I measured their resistance with the HP turned off in green....05-30-2024, 04:10 AM -
I have got an Steeldigi Steelshock 4 v2 controller won't draw any amp from outlet.
I have disassembled and removed the battery. I have tied to measure some points. The usb connector shows 5 volts. There are test points and shows 5 volts everywhere it should. The battery connector in diode mode shows 0.009v is it ok?
There is an U4 chip place, but no chip, between the battery connector and the charging port.
How should I progress to identify the problem?
Can anyone help me with this?...Yesterday, 11:20 PM -

Hello dear badcappers!
The title pretty much says it all - do you, please, know if there's any way to troubleshoot which of the integrated RAM chips (LPDDR5X in this case) is faulty?
[B]Backstory: [/B]
After replacing the 4 onboard (soldered) memory chips on a RoG Ally (4x4 GB to 4x8 GB) it got stuck on the RoG logo. I assume one of the chips is either not soldered properly or faulty. However after reflowing and replacing bunch of them I am still stuck at the same place.
If there is a way to narrow down which memory module is faulty it would make my...Yesterday, 12:05 PM

I get backlights that stay on not there is no image. The tv does not automatically power on when plugged in either which I generally see happen when there is a fault. It responds as it should to the power button.
I checked the test points on the TCON and I have proper voltages except for at 1P15V. I don't know if that is supposed to be 15V or 5V, but either way I only get 1.134V on that point. I have 12V, 8V, VCC, and a small amount on the CKV point.
I tried heating up the SoC on the main board but that made no difference. Disconnecting either ribbon from the TCON also...06-01-2024, 08:55 PM -

Guys I have set top box which has no power on in specific case. When I insert antenna plug which has 12V on it because of dB gain device on top of antenna, device if its turned off, it will not turn on.
After I need to open the case and short + and - on ABS10 chip and after that device will turn on, without antenna plugged in, after its turned on I can plug in antenna and it will work fine, but I notice there is some extra heat inside the unit.
Is this chip okay? Rectifier bridge ABS10 JQC I don't think there should be connection like additional diode between plus and minus...06-02-2024, 03:09 AM
