Alienware 15 No Post Two Beep
Hi, I got this Alienware 15 one year ago, everything was fine until today.
i7 6700hq
980m
A Strange thing happened in this morning. The notebook somehow can't find the wifi hotspots so I turn off the computer and turn it back on to see if I can fix the issue. Then, the beep sound. Two beep possibly means RAM issue, so I tried to reseat and even replace the RAM, but with no luck.
Looking for some help, I know the motherboard's memory slots could be the cause, but I wish to hear someone's opinion about how this issue occurs in a sudden with no obvious indication.
One thing I have to mention, I did leave it on sleeping mode a lot, and sometimes I just let it run out of the batteries.

Try one memory stick at a time on each slot. If the issue persists please send me a PM with the Service Tag.

That troubleshooting article solved my problem for a short period. I got into the system and restarted several times with no problem. However, after I plugged my wireless mouse USB on, the same problem happened again after another reboot(No POST, two beeps). It also seems like I have to wait a day or two without powering up the computer and then repeat the troubleshooting processes to be able to boot the system. No idea what is really happening tho.

Update the Bios to the latest here (make sure to choose the OS accordingly).

I managed to install the Bios and had no trouble using the computer for a whole day. Then the same issue happened again when I was trying to turn on the computer today. I earlier confirmed that I have to wait one day for some reason to boot up the computer successfully. Now I guess I have to wait again and see if I can do anything to save it.
I also did a hardware stress test including memory, cpu, but no errors were found.

The touchpad is almost definitely going to lose its power(deactivated) every time I turn on the computer for about 10 to 15 mins. Also, I will get a no POST, two beeps warning while booting if I shut down the computer when the touchpad's power has lost. I would guess this is a motherboard related issue that causes power not to flow through parts correctly. However, I can use the computer without any trouble as long as I keep it on, or only restart it instead of turning off the laptop completely.
