i am sure all you need to do is pull the battery ... hold the power button for about 20 - 30 seconds ... plug the battery back in, and hey presto !!! your laptop should be functional again :)

Is it okay for the power LED to flash those 8-9 times as soon as I turn on the PC? Is it part of the Power On Self Test? Thanks in advance. ... Your system isn’t even getting past POST. Verify the socket has zero pins. Verify all cables. Essentially you should boot with only the CPU and memory installed, you should be able to confirm the system boots, by the diagnostic capability of the motherboard ... You should check what the blinks mean.

r/mffpc on Reddit: Why does the power LED keep blinking on AP201 once in a while?
October 30, 2023 -
I recently built my first PC with this beautiful PSU case. Everything is working fine. Except a minor issue.
The power LED (square white light with the power-on switch at the front panel) on the Asus AP201 PC case keeps blinking every other day (after a gap of say 24 hours or so). The PC doesn't hang or freeze and I am able to use it normally as the light blinks. The temperatures too are normal. The "problem" resolves itself once I restart the PC.
My PC serves as a server and I keep it running 24x7. I'm running Ubuntu on it with "Balanced" power settings.
Could you help me figure this out? Thanks.
[Edit - I opened the PC case and double checked the cables. Everything is fine. I'm not certain that this is an Ubuntu standby settings idiosyncrasy.]

r/ASUS on Reddit: Rapid blinking power LED on Asus Prime Z690-P WIFI
January 6, 2022 -
Hello,
I am wondering if anyone else has had the experience I have had...
I finally decided to build a new machine and have not been able to get it to boot yet. No matter what I try I get a rapidly blinking power LED.
Here is what I have:
- MOBO: Asus Prime Z690-P WIFI
- CPU: i7-12700K
- Cooler: Noctua NH-D15
- RAM: VENGEANCE 32GB (2x16GB) DDR5 DRAM 4800MHz C40 (CMK32GX5M2A4800C40)
- SSD: Samsung 970 Pro
- GPU: NVidia GTX 960
When I press the power button it appears to power on normally but I never get the BIOS post screen and monitor never turns on. The power LED starts flashing rapidly pretty much immediately. I tried swapping the RAM around all the possible slot combinations, tried removing it completely. I get beeps with memory error code with RAM completely removed. No beeps when the RAM is in. Tried 2 different GPU's. Checked and rechecked every connection. Removed and disconnected everything except the bare minimum and still get the same thing.
Any input appreciated.
Thanks.

Got a replacement mobo. Looks like it has the same firmware as the original and still has the same issue. Waiting on different ram now. Hopefully different ram will work.

Tried different RAM and still have the same issue. Got an MSI board with LED's that actually show more debug info and it turns out it is the CPU ¯\_(ツ)_/¯ Now gotta figure out how to RMA it with MicroCenter or Intel. Thanks for the input everyone! Much appreciated!

For some reason, my router decided to stop working this morning, the power LED light is blinking slowly. The problem is the router is not even connecting to the computer using the cable. I tried to set it to recovery mode multiple times with no luck. Here is what I tried: -unplug router -press and hold reset button -plug router in Regardless of what i do, the power LED keeps flashing slowly and and i cant flash it using the asus recovery tool because it doesnt even connect with the cable plugged in. Anyone seen this issue before?
