Question

Asus k53sc motherboard

Aug 16, 2016 1:52PM PDT

I had a problem with the power socket on my motherboard(it broke). So I bought a soldering iron, and changed it... But I think I messed up something.
Now when I try to turn the laptop on, I see the lights go on, I can hear the fan spinning, there is power going to the CD... But other than that, nothing else happens... It just stays like that... No picture on the display, no backlight... No booting sounds....
Any ideas what I might've done... I'm new to those thing so any help will be appreciated... Thank you

I tried to clean the dryer thermal paste with white spirit... I was careful with it, but what is the possibility of me burning the processor

No one can diagnose those over the internet. If you slipped up and took out a trace or such, it's a new motherboard to fix it.

However since you are a PC tech, tell me the Volts on the CMOS battery.

Not a PC tech

I am aware that remote diagnostic is almost impossible... I was wondering on how to diagnose it myself... And my worst fear is, that even if I decide to buy another motherboard, is there a way to find out that the problem is not somewhere else... Like the processor for example.... The last thing I want to do is to start changing parts at random.
Thank you...

I'm a bit beyond a tech.

Here I design circuits, write code, have worked on cellular base station design and along the way owned and ran PC repair shops.

Taking a voltage measurement is a basic skill.

Anyhow, about that processor. To test that you place it in a working system. The test rig for a CPU is millions of dollars so the good old swap is how it's done in shops.

We don't change parts at random. We go for the most likely. In my experience I check basics like CMOS batteries and a visual for damage.

A long time ago, a wise tech shared gold. Here it is. "If you don't know which part, change the cheapest part first."
