My laptop turns on, but nothing shows up on the screen, and neither the keyboard nor the USB mouse works at all?
I bought a new MainGear Vector Pro laptop recently. It ran fine until last night when I moved from the U.S. to Europe because I had to change the wall plug for my European outlet. When I turn it on now, there is a low whirring sound as it starts. The power light turns on and stays lit, but the battery light stays dark. Some lights at the front of the laptop glow, but nothing else works: no screen shows anything, no mouse responds even though it's plugged in via USB, and the keyboard lights don't turn on or work. This happens whether I connect or disconnect the power. The laptop also seems to shut down and then restart again and again after being turned off. That is strange because everything worked perfectly last night. As usual, I left the lid closed when I finished using it. I tried different wall outlets, pulling cables apart and putting them back together, and even going back to the original AC cable. Nothing has helped yet. Any assistance would be very helpful! Here are my laptop's specs: AMD Ryzen 6000 series processor, Intel 12th Gen Core i9, NVIDIA GeForce RTX 3070 Ti, 32GB of RAM running at 4800 MHz using a 230W adapter with a lithium polymer battery and an 8200mAh capacity (charged from three cells).
Welcome to the forums! Even though your laptop is unplugged from the wall, if it helps, take the bottom off the laptop and separate them. Take the battery out of the motherboard, remove the memory sticks, keep pressing down on the power button for 30 seconds just to be safe, then plug in the adapter (not the battery) to turn it on. If it doesn't start right away, shut it down again, unplug from the wall, and try running on the battery only. To make sure things make sense, could you please share a link to that specific cable?
Welcome to the forums, new guy! Even though the laptop is unplugged from the wall, if it's okay for you, take the bottom part off and unplug the battery from the motherboard. Press down on the power button for about 30 seconds so it loses all charge, then plug in just the adapter (not the battery). If the computer turns on a bit weirdly, turn it off completely, disconnect everything from the wall, put the battery back in, and try turning it on again with just that battery. For better understanding, could you share a link to the cable you're talking about?
