current consumption of the laptop startup sequence ?

[corrize]

Hello, what is this sequence pls ? I just repaired pc laptop, and I want to test with minimal current (from PSU). And I would like to check on PSU if there is a good start.
It's a little 14' asus.
What is the difference between small laptop and gamer laptop ?

It’s a little 14’ asus.

Do you have the model number for this little Asus,and what is the motherboard part number. With the motherboard part number we can check if there`s an available schematic,boardview or Repair Guide.

Re: current consumption of the laptop startup sequence ?

It’s a general question, from your experienec, I have no idea at all of consumption at start sequence of any laptop.
I don’t need a precise curve, just an idea.
If after pressing start button, I see 0.2, 0.5, 1amp or 2amp, it is normal or not ? And after x sec, drop ou up to x… ? Do you see ?
If realy needed, it’s a ux433F Zenbook (i5 and no graphic card). But it is a general question.

Basic things are seeing if the current goes over 1A if battery is connected (so we know at the very least the charging circuit/battery are working). Look at the adaptor or on bottom lid to see what the machine is rated for peak current usage as a guide.

Disconnect the battery, you see what current is consumed at rest and when power button is pressed. The actual value per se isn't important (as this will be very much hardware specific). What we are really looking at from a diagnosis point of view is how it reacts to being plugged and when power button is pressed.

A static value indicates that the CPU isn't executing code for example. We can also see if the current goes up/down with RAM installed or removed. If we have varying current, this usually means the CPU is booting, and it might be a video issue if there is no display. Just rule of thumb.
