Re: identify component: red-brown with white Q
It sure helped, Meritosari, and the board is indeed a Pegatron, I found the code underneath the keyboard (where there was also an opening through which you could replace the fuse!).
It was enough to replace the FDMC8884 and the laptop was functioning again.
Thanks everyone!Leave a comment:

No "short to ground", but "on the ground": can you tell me what distinguishes the two?
On other Toshiba schemas I found plenty of these combinations: 2.2k resister - capacitor - ground.
Thanks, Gerard...Leave a comment:

I've removed the two components of which I'm sure they're toast.
Still hope someone (relax79?) will tell me if the short to ground is a problem....Leave a comment:

Re: identify component: red-brown with white Q
Couple of questions.
According to [url]http://mayohardware.blogspot.be/2011/02/tips-on-testing-mosfets.html[/url] I should be reading between 100 and 500 on the mosfets with a diode test. That's OK for the F8707, but on the FDMC 8884 I read only 64. Moreover, it looks a lot as if gate and source are shorted on the 8884, as with [url]https://www.badcaps.net/forum/showthread.php?t=41206[/url].
Then I have a short to ground where I've drawn two connected red circles on the attached picture. I didn't expect...Leave a comment:

Re: identify component: red-brown with white Q
This is exactly what I was looking for: Q = 10A vfa fuse. Bingo.

Re: identify component: red-brown with white Q
The motherboard belongs to a Toshiba C855-P21, intel core I3 + amd gpu, the image attached is not mine but a lookalike. What is the symbol for a fuse on a schema?
Thank you all!Leave a comment:

identify component: red-brown with white Q
Would someone tell me what the component is on the attached image? Red-brown color marked with white uppercase Q.
Thanks,

Re: New Members - please post your introductions here
Hallo, Gerard here. I love a challenge, so I'll try to revive a laptop motherboard my friend fried when powering it with the wrong polarity. I've got a simple question to get started, so I decided to register here, didn't find another forum with so much information as this one.Leave a comment:
