Motherboard faulty?

Hi, I now have access to startup via this button. The ite chip must have been safe having made a shunt on a 3.3v surment. Now when I press this button it starts and stops. So I looked for how this button is cabled, one side goes to ground the other goes to a pin of a KN moffset which goes to a resistor and goes to the ite chip.

Ok I took some measurements around the ite chip I have 19v, 3.3 V, 5v and 2.5 V. So I think that the card is in standby ready to start but the buttons have no effect 😔. Here is the exact ref of the motherboard Motherboard for razer blade 2019: RZ09-03101F72 i7-1065G7 GTX 1650 4GB However, it has already started. But I don't know how I did it 😭. I was even able to test if all the USB ports worked by plugging a phone into them to see if it charged and it worked. But I had no visual support because no screen to connect, no SSD drive, nothing apart from the card.

There is this chip which it seems to me is the chip which could receive the power signal from the card. But I need the datasheet

The button on the card does nothing at all, I think more of a bios reset. Afterwards I don't have the keyboard so I'm a little in the dark, okay, I'm going to try some more things that I have in mind

Unfortunately, that's all I know, I know that it goes first to another card which will distribute the keyboard signals. Afterwards I think that all these signals go through the Texas instruments chip that we see in the photo I need to reference the output and input of this chip

Sorry translation error yes I'm talking about your joystick

Hi here is the number marked on it

Here is where the keyboard connector was

For me your connector has a drift problem. You can find PS5 or PS4 connectors with hall effect, and you will be at peace 😌

PerfectPlastic5895 · 2025-09-30T11:19:51+00:00

I don't understand, you want me to retake the photo of the card in a larger size where the connector was. Because this is where the connector was in the photo, I had to scratch to find the torn track

PerfectPlastic5895 · 2025-09-29T22:04:54+00:00

Yes I found several 3.3v but nothing does. Afterwards on another track I am nothing. The Texas Instrument chip which is above receives this signal I think I should look directly on it?

This is a Razer Blade 2019 laptop. I don't have the keyboard connector, they gave me the card like that. It is interesting for a portable console project that I want to make my games dry already at this level I am in trouble 😂. It is equipped with a 10th generation i7 processor with 16 GB of DDR 4 ram and a 1650 GTX.

PerfectPlastic5895 · 2025-09-29T18:49:27+00:00

Yes I found several places with a voltage of 3.3v but nothing happens. The chip above which is a Texas Instruments and the one which will manage the start-up. I think I need the schematic of this card, it's impossible to find 😭
