Thanks so much for this informative video. I have searched lots of videos online and none comes close to the way you explain. The closest you find are Hindi videos with no subtitles. I even planned on learning the Hindi language just so I can better understand the concepts they were sharing, And from nowhere you APPEARED and how glad I am that I found your channel. I'll be looking forward to more informative videos from you. Thank You.

dude, you can't be serious when you say you wanted to learn Hindi . you can get laptop's components explained in English online in form of pdf books

Dude who explained it better than everyone else.

Thank you for this excellent video..Go ahead for informative videos..

The best explanation of super i/o, how it works. Thanks master.

Excellent presentation, the most clear I have ever seen, for that I am most grateful thankyou, I remember in the day when the SuperIO was on a card and controlled just the serial, parallel, floppy and IDE ports on desktops lol, back then component level repairs were uneconomical as it was cheaper to replace the card or board, now its gone full circle and its cheaper to replace the component. thanks again and look forward to seeing more from you.

Great video and explanation done in only 8 minutes. You should consider uploading more videos like this in your channels.

Would love to see a video on chip identification, pin identification and trouble shooting for these. Seems like the SIO is often involved in "laptop no power" situations, right behind bad FETs.

Great video... Thanks for sharing your knowledge... Greatings from Portugal 🇵🇹🌟

Hello sir , many thanks for your explanation. My question is after you get the VCC 3v, Ec rst, crystal oscillating 32.678 khz clock correct, the next is bios pin 1 which is chip select. I know of rsmrst confirming that PCH VCC is generated. Pls explain how the rsmrst is connected to the bin file of the bios rom?

@FixTronics

2 жыл бұрын

That isn't the Main bios I was talking about Its the EC bios Maybe I did not know to explain it well My English is really bad The main bios is not connected to SIO at all, its connected to the PCH straight away So if the EC or KBC bios bin file get corrupted then RSMRST will not be generated and you have to Reflash the EC bios Note: Nowadays the EC bios is not a separate chip but embedded within the EC chip itself so you have to refalsh the EC chip when its bios bin file gets corrupted

Thanks very much for this video, though I still have much learning to do.

The problem is, when I leave it for about 30mins while it's off, I won't be able to turn it on until I heat the sio again

When I heat the sio

Does the EC send the enable signal for the 5v and 3v always before or after sending the signal to PCH

@FixTronics

Жыл бұрын

The EC generates a single called EC_ON which work as Enable signal for both 3 and 5 volts always This happens before sending anything to the PCH If you watch this vedio it might give you more information kzread.info/dash/bejne/pqFqo5hsqtW2qdo.html

Or is it possible to reprogram only one sector of the hip where the EC is, and if I want to reprogram the KBC, can I find it in another sector where I can only reprogram the KBC?

Yes brother my mistake

With all due respect friend your sequence is wrong. If you check the sequence with osciloscope you will see that the first thing the EC does after receive power, clock and reset is fetch data stored in the EC ROM (Wrongly called BIOS) to configure its GPIO's. (ACIN, LIDSW, RSMRST, etc). I hope this will be helpful to you. Thanks.
