Can someone with the same motherboard measure if there is output data on the "UB1" ROM IC when connecting the AC-DC adapter? -
I initially ruled out RAM because there were no BIOS reads at any time.Leave a comment:

No short is measured on any coil.
Relatively low ohms on the +0.75LALW output (30 ohms and 60 ohms reverse).
[B]Can anyone confirm this is correct?[/B]
When connecting the AC plug, the "ALW" voltages appear (3V, 5V, 1.8V, and 0.75V), but they immediately drop to 0V, leaving only the +5VALW.
[B]Can anyone with the same board confirm this is correct? If not, can I suspect the EC?[/B]
The strange thing is that when I press the power button, all the "ALW" voltages are correct.
Note: Without a ROM BIOS chip, same b...Leave a comment:

I replaced the KBC with one from a different motherboard and it worked fine.
For anyone who might be interested, you obviously don't need to program it, just extract the firmware from the BIOS.Leave a comment:

Lenovo IdeaPad 1 15ALC7, motherboard JS471/JS573 NM-E541 Power on sequence?
Hello, I have this board in question. When I connect an AC-DC adapter charger (without a battery), the consumption is 19mA, with only +5VALW and 3VL present. When I press the power button, all voltages appear OK, the consumption rises to 260mA and remains stable. There's no video.
My question is if anyone has this board or information on the power-up sequence, and if the other ALW voltages are present when the load is connected.
What I noticed is that at first, 3VALW and 1.8VALW appear for a second or less. The BIOS is never read. Even so, the BIOS has been reprogrammed... -
EXO UX133 the KBC has pin shorted to ground
Hi, on the UX133U motherboard (little info) the KBC (IT8987) has pin 59 shorted to ground, so there is a key always pressed.
Does anyone know if it can be cancelled by modifying the bios bin or reprogramming the KBC?
Thanks. -
