I have checked the voltage at the wall. I am getting 19.3v from the transformer to the laptop. Voltage to the battery is 2.5v. Laptop gets 19.3v at the motherboard.

I have not been able to find information about proximity sensors/magnetic Reed switches but if there are, I can check them.

With all that said, am I looking at a bad power switch or possibly some other hardware issue? Just to be clear, the laptop does absolutely nothing when the button is pushed down. No lights, sound, nor anything that would indicate the laptop is booting.

can you please help me identify problem i have? Here is the link to video showing the problem

I had it before and i disassembled laptop, changed thermal paste and it was magically gone. But after some time it returned back. I tried to disassemble again but i brooked lcd cable. So i ordered a new hoping that the cable was the problem from the start. I replaced it and the problem is still there, you can see it on video.

HDMI and VGA output works, also in BIOS i see clear image, maybe just some noticeable flickering, maybe this is normal. Also in video you can see ASUS inscription is ok, only loading animation is distorted. Don't know why after ASUS logo loading screen, lcd goes wild.

Thank you for your advices! Don't have much trust in local repair workshops, they will say to change LCD panel or motherboard or something like that. I may do it, but i need to be shure that it will solve the problem.

I have Outlook 2003 and was emailed a pptx attachment. When I double click it, it always asks to save instead of opening it. Docx files open fine. I have the Office 2007 compatability pack installed. If I save the pptx file to my desktop i can open it from there, but not if I double click the attachment. Thanks for your help.

I was expecting that Windows 10 recognizes the new Bluray reader. Both, new and old one are form Hitachi-LG Data Storage.

I have tried this already:

• Driver updates from Windows Update → no updates needed
• ODD Auto Firmware Update from Hitachi-LG (https://hitachi-lg.com/en/support/firmwa...) → The optical disc drive already has last firmware
• I confirmed in the BIOS if the SATA configuration was ok, I can only change the SATA Mode from AHCI to IDE, so I let it on AHCI

is the laptop too old to use the Bluray drive, althought is SATA?

Any suggestion?

Thanks a lot for your support!!

I found the "Super Multi Blu Install Disc" (in the hope to find the Bluray drivers) → https://archive.org/details/super-multi-..., and ran the "BD advisor":

I’ve disassembled the laptop to see if there were scorch marks or other traces suggesting there is a problem from the battery connector to the print board. Nothing to see there. The nine pin connector that goes in the battery looks fine.

I do have a multimeter, but I don’t know what to measure for. Who can help me in the right direction?

My asus laptop freezes when im playing games especially when it uses Nvidia graphic card. Weird sound comes also when it freezes and there is no way to get rid of this freeze screen it pushes me to use power button to shut down my laptop. Sometimes it gives a warning which is nvidia kernel driver crash but im an engineer of electrical&electronics and im sure that this is not about the driver or software problem. I've sent my laptop to service twice and they are saying that there is no problem that they've noticed. Does anyone help about it because this technical service sucks.

Checked power supply output, OK. Replaced battery. Still will not power on. Tested RAM, OK. Fans do not spin when power switch is pushed. Conducted some cursory testing of the mother board with DMM and found voltage. So, power is getting to the motherboard. What could the problem be and what else should I look for?

Yes, it is confusing. What I posted are the only diagrams I can find for the ASUS N550 series. If you know of a source for diagrams and a service manual for an ASUS N550JK-DS71T, I would be grateful. And thinking that the issue might be the power switch, I purchased a replacement on ebay. The laptop won't power on with either switch. These images are of the insides of the laptop with and without components installed. The spreadsheet is the results of measuring the test points on the motherboard diagram, which hopefully is similar to the JK. The tests were done with the power supply connected and with it disconnected. Booth the battery and the CMOS battery have been replaced.
