changes thermal paste, Bios battery, Ram , even the processor , power Adapter
so what could be the issue?
Welcome to the forums, newcomer!
Take out the internal battery from your laptop and attempt to run it using just the adapter. If this resolves the issue, the problem lies with the battery.
If that doesn't work, unplug the device from the wall, ensure the battery is disconnected, remove the RAM modules, press and hold the power button on your laptop for 30 seconds to discharge any remaining power. While the RAM is removed, use an eraser to clean the gold contacts on the RAM slots. Reinsert the RAM. If you have two sticks, start with one in each slot, then the other. If the laptop restarts, power it off and install the second RAM stick.
Give them a whirl and keep us updated.
the video comes after i've completed that task
it uses the power adapter without the battery and just one piece of ram
Hey there.
Is there any sort of power indicator on the power cable PSU? The power brick could be dead, in which case, you'd be running on battery alone. If your battery is then depleted, the system will not start up, and you may see keys light up for s second or two because there is no power in the battery for any more than that.
You may need to consider a new power brick. Bring to local store and get them to test with a new power brick.
Hello everyone
First, I'd like to thank you all for your efforts and wish you all the best in helping. I really appreciate it.
I've replaced the entire adapter with its own cable and it worked just as expected.
I also removed the laptop battery before testing, and the video now works without the battery, using the new adapter.
I checked both adapter outputs with a multimeter and they are functioning properly.
I believe the problem might be at the motherboard level. I'm not sure who can assist me in diagnosing this issue.
