Acer Swift SF315 no power - Part 2 - IO/EC/SIO chip programming

[repairfreak]

My God man, how can you deal with all those surface mount components, not to mention the lack of schematics and information on so many boards nowadays. I’ve been at stereo amp and tv repair on off for past 30 years and I still scratch my head trying to understand circuits with schematics. However I have never had a mentor or teacher, just book reading and exploring is my teacher. Props to you sir, I wish you the very best with this tricky repair.

Sorin, you have proper mad soldering skills, I can only wish I could do what you do, with those small SMD components, totally amazing. Paul, USA!

[KevinR]

Almost there very impressive your patience is great and your hot air is faster than mine ever is. I'm also impressed with some of the comments of this channel good work comes from intelligent people all over the world.

Sorin You are a great artist and genius at finding solutions in laptop repair and you do a job that 99% of laptop repair technicians can't do.

Hello Sorin, I want you to know that you have a big fan here in Brazil - I like your analytical thinking - keep going!

[albundy]

I am very impressed Sorin. How you fight to get it running again. I would have given up 20 times. If I could I would give you 100 thumbs up.

Hi Sorin, for bios programmer you have selected, you need 1.8V adapter otherwise you will damage the bios chip

[Shubietah]

Hi Sorin. i have similar programmer & i used it since long time, it's very good, but it's complicated sometime as i have to find schematic to map KB connectors for unlisted boards, however you are getting error because you didn't connect the usb cable from the programmer board to the laptop for proper grounding, ... always learn from you Boss !!

Before we do the BIOS, try to remove the keyboard, disconnect it from the board, then disconnect both batteries, CMOS and the big battery, look for 3.3V on the keyboard connecter on the main board side, and short it to the ground with the charger plugged in. Maybe the Keyboard power button is not working too, very common problem in new lap tops with power button on keyboard.

One trick is to use Kapton tape on the reverse side to hold the components in place. You can also surround that chip with Kapton tape to protect the components around that quad pack.

Și luptă și dăi și luptă și dăi... Sorin nu te lași... Se vede că o faci din pasiune. Dar toate până la un punct. Eu zic că trebuie să calculezi timpul, efortul și costul unei astfel de reparații. Dacă nu rentează nu trebuie să mergi mai departe. Sănătate!

Actually in my country, right now it's, 11:57 pm, but I'd much liked to watch this now, though I'm tired and got to sleep, because I have to be awake, early morning, but I'll surely have to watch this in the morning tomorrow.
Though I've just liked the video already in advance.

You found another bad part, but it is troubling what caused all the damage. I think you'll solve it if you continue on. Seems likely the next step would be to reprogram the BIOS though. I'll be waiting for part 3. 🙂

Found it on ebay, it is an "ITE ENE Mic IO Programmer"

[FixTronics]

Sorin I have two videos on my channel explaining about this exact programmer and how to add your Motherboard into it.

[laboratorioassembler]

You can program the bios using crisis recovery procedure... usb drive fn+esc ( this also can spot a fan spin )

[robbirobson]

Many times if you download bios file it comes with bios and ec rom, i think you need to flash them both to have the same version. if you mix from a different version it may not start. happened to me a while back. however with this much damage on the board maybe its not that. if ec and bios and charging ic works you should have at least charging light, if you dont get charging light maybe some signal is missing, you need to check ac detect ac on pwr good etc... maybe some logic gate somewhere or transistor switch got burned as well.

Greetings Sorin, during programming I would connect a second USB cable labeled GND. It serves to unify the potential of the board with the programmer. The same cable is used as for connecting the control PC.just plug it into the USB on the repaired board.

[DanielsGameVault]

My 2 cents is that the BIN you wrote on the ITE chip doesn't match the BIN on the EEPROM chip, so it doesn't "know" how to respond to the power button being pressed...I THINK. Really curious to see how this turns out.

[Marek_LapRem]

Hi sorin. this vertyanov programmer is better than svod3. svod4 turned out to be a failure. It is very important to connect the second USB socket of the programmer to the usb of the motherboard to get GND. You programmed without GND. Greetings from Poland
