I have and Asus Q409ZA that I purchased new, and all was well until it eventually turned on to a black screen.
I backed up my original BIOS. I then downloaded and flashed an engineering BIOS posted by another member. It works great until something updates and the laptop starts up to a black screen, no activity. It can be reflashed with the engineering BIOS and work again until etc. etc.
I've attached the original dump of this laptop with its serial number and other information in tact. I've also included the new engineering BIOS. Maybe somebody could take a look and...Today, 02:29 PM -
Hello everyone, I need some help with a PS5 Slim board EDM-040 that will beep but no light or fan spin.
When I connect my bench power supply, (12v 0.500amp) the amps go between .135-.035 then back to .005.
When I attach UART I get the error code below. I have replaced the DDR4 ram IC with one from a donor board. Cannot verify is the IC was working or not, still same error.

Hi Peeps.
Quick question. Might sound silly so bear with me pls.
After flashing a BIOS with a flashing tool, my laptop went from stone dead, to the fan spinning. However the screen doesnt show POST. Is there anything like pulling out the battery AFTER flashing the BIOS one needs to do or is there another issue I am sitting with now?Today, 01:00 PM -

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
W= V * I...Yesterday, 01:58 AM -
