ASUS 1201HA - Impossible to repair?

[Chris_abr]

Hello. I have a spare laptop laying around, and all I know, it doesn't work.

The power jack seems to be removed, and one of the components on the motherboard.

I'm not 100% sure what component it is, but when looking at the oryginal (working), it looked exactly the same as the one in red circle.

Do you think I'll be able to find this component easily?

I'm not an expert in electronics, but I can work with a solder. Just not sure what component it is, and whether it's possible to solder it in.

See attached photo of the motherboard.

I'd really appreciate any help.

TBH you cannot guess what the component is by the size of the lands that it solders on to.

Even if you did you should use the correct tools and techniques to fit it or you could easily damage the component

You could just try fitting a new power jack and ignoring the other component. It looks like a capacitor, so it might not be vital. It's got to be worth a try hasn't it?

I've got some tools. I'm not an electrician, but just a DIY'er with Weller soldering iron, and a couple of tools.

But I need help, as I've never done those SMD/SMT components.

How do you identify them then?

Is it by the colour? Their size?

Because it was exactly the same as the one circled.

And yes, perhaps I could try it without soldering that component, but wouldn't it all burn when I connect the power?

Sorry for asking such basic questions. I don't know much about electronics, just the bare basics, and things from my DIY work with speakers, etc. This is something new.

EDIT:

I'm not sure, but I've just found this website:

SMD / SMT Resistor :: Radio-Electronics.Com

And compared the size of the resistors there to the one that should be on my board, and it seems like it's the 0402 one.

So is there only one type of 0402 capacitor? Or are there many types of this?

A common fault with laptops is that they get left on the floor and people trip over the power lead. Do it a few times and the DC power jack will break away from the board, sometimes not before some localised charring has occurred through a bad connection! Some of the solders used on those SMT boards are incredibly hard to get flowing with a hand soldering gun.

0402 is I think you will find dictates the type and in turn PHYSICAL size of resistor but NOT the ohmic value, see here:

Sorry, I made a mistake in my previous post. I typed resistor, instead of capacitor.

I understand that capacitor keeps some power in it, so I suppose, if I bought a capacitor with the chargers voltage and high capacity, it should work?

Chargers details:

Input: AC100-240V, 50-60Hz (presumably standard) 1.0A

Output: 19V 2.1A (LPS)

EDIT:

After doing some research I have found, that because this capacitor is light brown, it's probably between 1nF to 100nF, and the voltage is probably 16 or 25 (as the charger is 19 volts).

So that narrows the search.

If I found a 16 Volt and 25 volt SMT capacitors, with 47pf, and 100pf, the 100pf one with -20 + 80 tolerance, the 47 one with +/- 10.

Am I right in assuming that the more tolerance,the better for my case ?
