Did this video help you?

savichovich: hello and thanks two things here really , how did you come to this conclusion regarding the voltage over R285 to be 19v ??? there are two adjacent resistors which will divide the voltage ,!! second: in order to do that you need to inform the people how they can get the schematics otherwise they cant apply tests for other pcbs ... other than that thumb UP well done .. keep it up and Thank you!

Sherif Aliti: What if you check power tree directly from dc-in to battery out, isn't shorter way ?

BiMi UK: where u getting the schematics from :/ ???

Martin Flores: Hi, I have a dell inspiron 3520 laptop and it doesn't turn on, could you please guide me how to repair it?

Benedicta Arhin: Thanks for ur video but couldn't see where u put ur negative wire before testing. Thanks 

Selorm Kwame Yikimey: A good one there kudos 

Chanthachon Senesouphap: I think I found the problem of your board, there is a mosfet below D20 it has some small holes on it.

Preecha Bud: very nice good teching

sujit prodhan: nice

Stephane R.: Where did you get the service manual? I need one for my Toshiba L650D

Aaron Baron: Cool

Sadek Oussalah: I've got aquestion if you don't mind, the acer mobo i have will see the amber light if the battery is inserted but when only power it's dead, where to check thanks in advence

Celynjo05: sir how about the battery that 0% available plug in, charging. but my battery wont increased the battery percent. please help.

Donald Ellett: Very interesting

Shariq Syed: nice video give more tips sir

Laptop Repair Brighton: Nice how to video.

zaldy dada: men i want to know were to find your schematics

fish hook: was confusing in where yu said it was 10v the area read 125v,,, whereyou said 5v it didnt say anything

funnyazfuk: fk me, he likes to repeat himself.... :/ could have done it in 3mins

gaasl89: hi guys ,i want a name of a book that explain the laptop circuits in details and its voltage distributions ?

Ronaldo Farias: bom

Raf De Simone: Hello where can I buy the scanner?

patcom fixer: Great Video dude, I've been looking for this tip for a while.. Cheers from Canada

Joaquin Cortes: Hello fixitdaz,Have an Aspire, when I connect a charger (19 V) with the laptop off the battery loads fine, but when I turn it on charging lights flash and asks me to conect the charger. Only with the battery works fine, and I tried it with other chargers and does the same, I tried it with a 20 votls that if it worked well, which parts should I check? Thank you very much for the videos, they are very good.

Doom2pro: I never understand why people refuse to call a component by it's real name, Inductor. All "coils" are inductors but not all Inductors are "coils". It's no different than when someone calls an SMD Capacitor a "condenser".

Kamlesh Gupta: Like this video...

LSI INDIA: http://www.laptopsparesindia.com/, we deliver quality laptop spares sales through online. Just a browse over our website will give a clear view of what our organization stress upon.

fixitdaz: Hola, tengo un feliz lugar acer voy a ver lo que puedo hacer, y gracias por su atención gracias.

Rogelio Ga: Excellent video, thank you very much. I have a question: you put the yellow tags to the voltages, or are included in the scheme?.

linglingjr: Did you make the schematic for the AC circuit or find it on the web? I can't find any schematics for a laptop I'm trying to fix the charging circuit on: Asus K60ij

jazzman427: This is great, very nice of you to share. Where is the best site to get schematics at minimal cost?

Adel Arzadon: Hi sir, can you please help me, I have an HP nw8440 mobile workstation and when I turn it on it runs for around 1-2hrs and then shuts down. After I click on the power button, it no longer turns on and I have to wait for about 5-10min. It's not an overheating problem since I already clean the fan and added deepcool z9 thermal paste. When I discharge the power (by pressing the power button for 30sec.) it then turns on for while then shuts down again. Thanks, any advice will do.

Chris Barrios Harrison: Hola. Thanks for the reply, nice to see the tech help world still has some rolling stones :) Tried each of the links with no success, seems like I've stumbled upon a more secretive line of Acer!

fixitdaz: Hi PLAlfa, Its not written this is what i got out of the charging chip, then it was doubled up to 10 volts before it gets to the battery. if you are testing a charging circuit the characteristics may be different depending on the motherboard make and model, you would have to look up the chip and see what the output voltages are.

fixitdaz: Iv you go too Part two of this video there are some schematics listed in the description. Hope this helps.

ali shah: great vedios

240pixel: I have Lenovo 3000 n200, witch stops charging battery after few minutes. battery is brand new, and one thing I've noticed, when it stops charging, if you remove a battery (pc is on AC adapter) it turns off. I think its the charging chip's fault. thanks for the video. I will try to check it.

john a: what would be really great is you taking an old laptop which does not work and make it come to life. An excellent video. As you say if you can fault find the parts on one laptop and are able to read schematics then you can apply it to another; Thanks.

fixitdaz: Thanks.

computertechled: great video men i hope you keep up with the training

whitetiburon: Man brother you are AWESOME!! I have a mac mini 2009 with no power. Is there any way I could get the schematic for a mac mini?

Chris Barrios Harrison: Hi again, MB.TW506.001 is the part number but still no joy :(
