Acer aspire N17C4 coming on, goes off, flashing charging light, insane job 

This board has a switch next to RAM, which is pressed from the bottom shell and it activates the battery.

11:43 - Mr. Sorin casually pulling out an actual scalpel and then basically performing surgery on the battery

Another amazing fix Sorin, achieved by determination and electronic fault finding skills.

Great video Sorin very educational . Thanks for sharing your electronic knowledge

I have read the comments about the battery bottom cover switch. But i still believe that we have all learnt something. (As Louis Rossmann would say )

You are a genius Sorin..thanks for sharing your knoweldge with us

Amazing detective skills (and advanced electronics knowledge)...chapeau!

Bravo Sorin. Excellent find ! Bravo

Sorin you are the biggest electronics. I am sure nothing else I find and solve that problem except you. ❤

Thanks a lot for sharing this huge amount of knowledge ❤❤❤❤❤

A great work with the discharged battery 👍👍

That was brilliant, you a still the master.i realy love to see how you work on multiple propblem laptops,you a guineus .

Perfekt :D I like that fraze PERFECT

I didn't know there's a switch connecting the enable pin to ground after reading the comments so i think this is a solid repair i just would put a tiny proper calibrated fuse instead of a solder blob imo, nice job

Each video is better than the last. It is amazing how you apply your instinct and knowledgement against some silly modern stupid and useless things that manufacturers do. ,,

Crazy stuff, ghood job sir :)

Thank you.

Waw good job! I am so disapointed that some companies decide their computer can t work without a battery plugged in.. My computer works with no battery for years, hope for no general cut 🤞🏻🤞🏻🤞🏻😄 Thank you anyway for your videos! ❤

Many thanks Sir

Good job mate 👍

You are Great - I love to see your Videos - The Best

Fantastic Sorin

Excellent Sorin

Waw that was amazing sir

Thanks for this helpful video, logical question, what is the cause of this problem or it's a phenomenon, it's faulty related to the PCB or the battery, unless you have a protection switch pressed when the bottom cover is installed to enable the battery and run the laptop.

Maybe that link from orange pin/wire continuation on motherboard is somewhere broked. At some point you can see where it goes that pin with a schematics. Maybe somewhere a chip disable the line to ground from that pin, and when battery died, that chip disabled line to ground from that pin. Maybe if you upload a new fresh bios, it will work without that bridge.

Sorin the wizard. you're the best !

i have NEVER seen anyone work on a battery before. this is god's work.

Wow, I never would have guessed a battery ground issue. Learned something new - thank you !!!

Wow! and thank you. You are a genius lol👍

you are a great master

wow Sorin very impressive :)

Like a detective movie! Exciting and twisty! Amazing!

Sorin :) it's an acer laptop... there is a switch that cut off battery power when someone opens the RAM slot... this is made to not kill the ram controller during ram expansion :) check the memory expansion cover... you can find the switch.

Nice video

I learnt more from the video. but my question is, is it not possible for the laptop to turn on with adapter only (with the battery unplugged)

Great teachers

Hi, Sorin. I'm not quite sure, but there's a device missing in your channel repairs list. I think it would be very interesting to fix up a NoBreak device for an electronics repairs school. Just for give us a break (no pun...!) from laptops and phone repairs. Regards.

In my case my laptop is turning on. When I open some intensive apps like games it automaticaly shutdown with no reason. I already cleaned the fan and changed the thermal paste

I have a similar issue with my acer laptop. But theing is that sometimes it'll charge fine. Sometimes the orange light will blink. Sometimes the orange light will never come on. Other times when it is charging just fine, and i just start a heavy application or connect my phone to my laptop to charge, it will start blinking again and the chargung will be improper. Could this just be a charger issue? Because i have noticed that when i try to adjust my power cord it may go from working to not working. And not working to working

Can we replace laptop battery pcb (bms) with other battery but I have not same model battery can we replace with other models

Interesting No power to the chip where dus it supposed to come from? If there is no wire soldered

Great and really useful video. The first actual 'shortcut' would be to literally Google the model and 'orange LED slow flash'. I don't know the model, but to me that looked like the laptop is reporting a battery problem the moment it started flashing. The fix, ingenious. But the first shortcut seemed to get missed. 🙂

Good evening mister please what name the programme that you use to charge battery ?

I think there is switch to enabling the battery

sir der A battery Schick on ram side to use plz puss this bontun and battery charger

There's an smd switch near the ram: when the back cover is closed, that switch is normally pressed and closed and needs to be so or the computer won't neither work nor charging the battery.

Owesome

Genius

WOW this laptop is just like my Acer aspire 3 only deference is mine has nvidia graphic everything else is the same my motherboard model is LA-E892P

I hate these types of faults, why do manufacturers use these stupid ID pins to things like battery OR charger. They over complicate things that should function simply. Good job Sorin for finding the fault once again.

😂😂😂 Wow Dodge Repair... I Love It... I Want To Ask One Question... As We Put A Jumper Wire Externally To Enable The Battery... So Is There Any One More Fuse Or A Resistor Internal Side Of The Battery PCB, Which Is Doing The Job Of Enable The Battery By Default... 🤔 As You Are Saying It Must Be Enable By Default...

Was that Pin 3 the "system present" pin? That really should be connected to ground. I can't imagine why it was not. A very strange problem!

Sir i need bio this laptop can you give me

😄sorin, no matter what piece of crap it is, it's always "it's a nice laptop"

menakjubkan

If you have electronic trouble, try removing the button cell, all other parts, and leave the motherboard for one day. The laptop will full reset.

I see the video your battery connected not properly sold

Ugly fault and brilliant solution. Great, Sorin!.

WoOoOoOoOoOoOoOoOoOoOoOoOoOoOoOoOoOoOoOoOoOoOoOoOoOoOoOoOoW amazing 👍👍👍👍👍👍

so weird. I Wonder what it was

😍

Insane job it was but informative. Thanks.

😊😊😊i literally died when you said "lets solder that pin to ground" gj Sorin

Wau,this was challenging even for master himself! But Sorin solved it gracefully as always,nice job!

Always impressed by how much sorin can infer from such small amount of information

Fault finding of the highest order .. you should of been a detective 😂😂 . Thanks for the education here, next time I'm stuck on a problem il remember this one and keep at it . Best of luck Sorin

Tricky fault! By the way, what device do you use to diagnose the battery?

simply a piece of jumper wire for solving stupid mechanism 🎉

sorin, did you find any other way to unlock a battery without this device?

CRAZY !!!!! Always learning.

Възхищавам се на лекотата с която прилага знанията си ! :)

Awesome diagnosis process!!!

It was very interesting, a tough fixing.

battery on/off button have this model close back cover battery charging and good job for battery reparing BOSS

I just repaired a Dell doing the same thing. I tried everything. Last thing on my list was to replace the cmos battery. Dell is now working!

always we learn new stuff ,thank you for sharing all thjose information

Can it be legal issue if fixed battery catch fire later ?

A diode in line with that negative(orange) wire maybe blown? Be nice to know why negative was lost. That was some VERY useful info to know! Thanks Sorin!

Some Acer laptops has a switch which pressed by the bottom cover of the laptop and then only battery activate(protection system). maybe this is the reason sir

i think on board have a switch for activate charging, when the cover is removed the switch is open.

No Sorin, No fix :)

Normal ca iubim lenea :))

this is insane

I think above the ram on the right side of that 8 pin soic there is a switch and thats probably a chassis sensor to check if the back is closed, probably that one shorts the enable pin to ground as soon as the back is closed my framework laptop has one of these switches as well and it makes both charging lights flash when the laptop is still on and open edit: still doesnt explain why the flashing charging light went away and came back later :/ maybe someone else got an idea

interesting
