Re: Idea for protecting DC-DC converters on laptop boards ?

It probably does - surely those gates wouldn't be flapping in the wind like that, but I was mostly referring to the situation where the IC is removed or disconnected like it happened to me.

Lightbulb Idea for protecting DC-DC converters on laptop boards ?

Good day folks. So I've been struggling with laptop motherboards for a while now. Most of my repair attempts so far have failed one way or another, mostly due to a lack of tools rather than human...

Re: Samsung NP-R60s NO POWER (PRAHA_SRE Rev 1.1)

But in this case I'm not getting the stuff before RSMRST anyway, so I don't think it's a priority yet. Besides, it comes out of the KBC too, so if there's a problem with it there's nothing I can do...

Thumbs up Re: Samsung NP-R60s NO POWER (PRAHA_SRE Rev 1.1)

What is this signal doing exactly and how would it be related to my problem ?

Yeah, it means it's got a blank chip on there now....I still have the old one, though I sure hope it's still...

Re: Asus ROG gl752v dead touchpad

Hmm....not sure what these guys installed on it since it wasn't technically my project, so it could be a driver issue after all, though I don't recall an instance where the touchpad wasn't working...

Re: Asus ROG gl752v dead touchpad

I believe Hirens counts as one of those non-Windows platforms which should load the touchpad by default just like a regular mouse.

Also upgraded BIOS to the latest version, forgot to mention...

Re: Reballing discussion and tips

From what I gather, he ended up reballing the thing and it's working, so it turns out a loose chip in need of reballing CAN cause only one video output to fail...

Re: Philips 32PHH4509/88 not responding to remote/not turning OFF

Sounds like a bad backlight LED to me. If you haven't already, try locating the "Backlight ON" pin on the connector coming from the main board and measure it with the TV on. You should have a voltage...

Re: HP DV6-6120us blinking cursor on black screen (BIOS ?)

No - it's working, so it wasn't necessary. It wouldn't boot off of USB either, so it wasn't the OS that was causing the issue :)

Re: Let's talk about SCADA

Re: HP DV6-6120us blinking cursor on black screen (BIOS ?)

Interesting. Unfortunately my BIN is larger than the one shown in the video - his is 4.12Mb, mine is 4.44Mb, so I don't know where the EC region starts and where I should start "chopping" the file...

Good to know. These guys may very well be willing to invest an insane amount of cash in this project like that in the long run, hence why it'd be ideal to keep costs to a minimum so the bulk of cash...

No, it's not quite a split bridge like the one pictured, though one of the compounds DOES have a single-leaf (?) drawbridge as part of its system. This is actually a water-lock: it lowers or raises...
