    Hi
    I'm trying to repair the GBA SP of a friend. It's a blueish-purple color. It has no visible damage anywhere. I cannot turn it on.
    When plugged in, the orange light lights up and it charges forever. I assumed the battery was dead, so I bought a new one. The GBA sp then charged for like 3 hours, and then the led vanished.

    When I try to power it on, nothing happens at all. I thought the issue would be with the power switch, even though it looks almost new, so I opened up the GBA and triggered the switch on the motherboard by myself. Nothing happens either.
    What could the problem be, and is there another way to turn on this GBA SP ?

    The motherboard looks clean and without damage, on both sides.

    Mostly, these kind of issues come from a dirty power switch. At least that's what I mostly experience (I buy broken Gameboys and repair them as a hobby).
    If you've got a soldering iron, try and follow this tutorial:
    The video shows a normal GBA but the SP uses the exact same power switch.

    I do not have a soldering iron. Is there any possibility for me to shortcut this system to simulate a power-on on the motherboard?

    No, not if the power switch isn't making contact, which is probably the case. You could try to get some 99% isopropyl alcohol, put it on a q-tip and just rub that q-tip into the switch. But that won't be anywhere near as effective. In my experience, if the switch is that corroded that the system isn't powering on at all, then only a full disassembly helps.
