by PrzmxHello everyone,
I'm an owner of an Asus Vivobook S 14 Flip OLED TP3402 laptop (TP3402ZA-KN063WA)
with serial number: NBN0LP019584459
and I lost the BIOS password that I set in this laptop one year ago.
I tried to recover the password using the AMITSESetup method described on the forum. I found that it is possible by software to obtain the BIOS file from my computer (afuwin.rom), but when trying to do so in AFUWINGUIx64 I received the error number 31 "Unable to read contents from specified file" shown in the attachment. I don't have a programmer,...-

by cheeky2See attached picture. I have a Fluke T100 Voltage Tester that the resistance and diode measurement isn't working (it's not the batteries (as I have already checked them and put decent Duracell 1.5V AAA batteries inside it).
I have looked on the web for any information and on youtube without any results for this model.
There are no screws visible or anything obvious. So I am hoping someone here has the solution to take it apart?
The only way I can see is underneath the yellow rubber handle area, however I don't wish to damage it if it isn't the case!...Yesterday, 07:21 AM -

I need help with a laptop Dell with LA-D801P motherboard.
The laptop completely died, no power, no leds.
The voltage of 19V is present at the output of the second mosfet.
The voltage on Pin 9 and 19 of PU102 is 0V.
Voltage on
PU100 :
pin2 =19v
pin11 =4.16v
pin12 =0.18v
pin17 =0v
pin19 =0v
I have 0 ohms on the coils PL100, PL301 and PL700.
If I remove pjp102 the short remains on the side of +3VALW.
Then I removed pjp501 and pjp801 but the short did not go to the integrated PU500 and PU800.

I post this in this section for a Dell Inspiron 3477 All in one as the motherboard is more close to a laptop one.
So, the issue is that whatever adapter I use, I get this screen when it starts up. I tried aftermarket adapters and original HP adapters, both 65W and 90W. Minimum requirement is 65W.
I don't have its authentic Dell adapter as I took it for free in case I manage to repair it, but the HP ones I think are pretty much identical.
First thing I checked is if the dc jack on the board has an issue but with the MM I see all three pins, ground, 19.5V and...Yesterday, 10:52 AM -

I have a HP 15s-eq1096AU with a failed bios
I found a HP exe that allowed me to pull the bin and i entered my key in @8000-8030 & serial @00-FF
This booted to a screen saying clearing bios block 0-630 then restarted to blinking caplocks key reporting broken bios again
If anyone could make me a bios with the DMA info etc from this dump that would be greatly appreciated...-

by OmronI 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
