more like "if the car doesn't start, it must be the key"😊
I actually know someone who would say that and then pay to have a new key cut before checking the car.😄
🤣🤣🤣🤣🤣🤣🤣🤣@@dang48
Simple is good!
Another great vid, i am learning alot from you.👍👍 many thanks
That diagnosing logic of "button doesn't work so it must be the button" is unfortunately a plague within the trades. I do refrigeration work and it's distressing how many people just replace parts without verifying anything.
Absolutely, many buttons, can have many interlocks...😂
"We have picture!, I can't believe" 😉
That unholy samsung/apple core2duo could easily still run linux and play internet radio all day long in a garage or something. Nice to see it fixed. Bench power supplies are invaluable. I bought one specifically after watching you and Sorin using them
It doesn't have to be reduced to "internet radio". Assuming it has a decent Core 2 (if it's a Merom it should be upgradable to Penryn), this can play Full HD RUclips videos fine, a lot of people don't need much more than that. Preferable to have 4GB of RAM and an SSD of course, especially if using Windows.
Sadly getting it fixed and upgraded at a repair shop is generally not worth it economically.
@@piernov True. For whatever reason Andy wanted me to fix it and I did. Neither have come back so the first one must be good with another PSU. I did say the batteries are probably bad but he was OK with that.
Heya 2 older laptops and after 18:16 they both are fixed lol well done richard
16:20 i knew it would boot at that time, because the current was higher than the other times
An that is the point of the video 🙂
if you have dealt with any one that had a valve t.v they use to come in wonting a picture or sound valve ?
when the picture valve was really the tube that did not often go in them day's but that was what they thought .
I believe the bios was corrupt and got reset when you removed the battery for awhile, it's intresting because i wasn't expecting the cmos battery to prevent the pc from booting
Had one of these and the cmos battery required the whole be disassembled for replacement.
Ouch.
Bad design.
That's often the case, maybe I just got lucky but gynecology through a letter box is a useful skill 😅
Stupid question: Instead of modding that universal charger, couldn't you just put a DMM in amp mode in series with in the output? There are even inexpensive clamp meters that can measure DC (e.g. Uni-T UT 210E). Don't know how precise they'd be but perhaps worth a test. All you'd have to do is separate the positive from the negative wire in the output. You wouldn't even have to cut wires.
Nice job. Those tact switches fail all the time, maybe they're not used on these things. But they do fail 😄.
Hello, for your attention, that is not a Samsung apple, it is an apple Samsung. 😂
I’m going to be working with audio amps. Some rails require 100V. What power supply configuration would you suggest?
For safety you should have:
1. Mains isolation transformer
2. "Dim bulb" current limiter
3. 0 to 250 Volt autotransformer or "Variac".
Paul Carlson from Mr. Carlson's Lab has info about this.
@@anthonyshiels9273 aren’t variacs AC & high voltage rails on amps DC?
@@jonathanrose456correct but it is not advisable to apply the full mains voltage to a device that MAY have shorted capacitors in it per Mr. Carlson's Lab advice.
I NOT going to transcribe his 30 minute RUclips video here.
Its not the switch but just a loose wire !!!!🤣
Good job! Nice repair, I'll try to replicate something similar on my Channel too. Thank you
Ahh another RUclips creator, welcome to the club. Did you see my video about how I set up a YT recording studio in my workshop? ruclips.net/video/yrVwkJidC9Y/видео.html
@@LearnElectronicsRepair It's really interesting, I'll definitely take inspiration! Thank you
I don't believe the battery will prevent the puter from booting.
A bad battery can definitely prevent the machine from completing POST (or from turning on at all). Seen that with low-end Toshiba like C50/C55, but I'm sure it can happen to others.
@@piernov True - I've seen this with desktop motherboards too
@@LearnElectronicsRepairI was thinking about the main battery pack of the laptop, but this is indeed true for the RTC coin cell battery as well.
Good example on desktops is the garbage ECS RC410-M2 board. The RTCRST# signal is derived from the coin cell battery voltage, rather than after the dual diode (to get voltage from the 3VSB rail when available), so low or missing battery will cause erratic behaviour during POST.
Asus desktop motherboards wont boot if the CMOS battery is depleted.
