how to repair windows 7
The failed cap was on the 19V rail, not on the 1.2V rail, so make sure you used a 25V rated cap and not a 6.3V one.
Exact capacitance doesn't matter that much if it's a few µF.
Very unfair, just because of spinning HD and 1 stick of ram? Maybe the customer more likely doesn’t know this and he could upgrade his components or he may not have the money for upgrade, in any case, you’re being very judgemental and possibly be rude in making these comments
Hi! Do you use a particlar brand/supplier for your SMD capacitors or just some random ones of Amazon/Alixpress? Thanks.
They're always 10uF, unless they aren't. 😅
Could we have a Pinecil repair video, please?
Adam, another fantastic video. Thank you for posting. Very informative.
Do you really have to replace the caps? I've been wathich Electronics Repair School videos as well and he never replaces them and even explained why. I just want to know another point of view.
have you got any aluminium tape?
I wish that i had all that tech knowledge as i have an HP laptop that stopped charging and thought it was the battery so i got a spare one from ebay. It turned on and reinstalled windows so i thought that was it, but a while after i noticed it still wasn't charging and was close to shutting down… and it did giving no chance to check the bios and unfortunately it's one of those laptops that doesn't have a bios battery so i can't take one out to reset it. It's also frustrating that i have no way of charging the battery outside of the actual laptop.
On these SoC laptops, at the manufacturer, is there a less or lower concern about fully removing (cleaning) flux residue from the mobo?
You know this wouldn't be a bad laptop with an SSD and an extra stick of RAM and maybe Linux Mint instead of Windows. Plenty of horsepower for most day to day use.
Laptop of bs series speaks for itself 🤣
I started my electrical engineering journey from your videos. I've since discovered Sorin, Northbridge Fix and Northwestrepair. I always seem to come back to your videos and learn something every time.
What thermal camera you used bro
cool
😄 Desoldering both, then loosing the good one? Now that's what you get if you don't go the Sorin route. You should maybe get a JBC nase-2C. Can't recommend it enough. It's such a fast thing to desolder everything that is SMD and has two joints only.
most people dont know about cat brand smartphone Sir which is amazing for me beside hp laptop
PC I'm watching this on had a shorted cap on the memory power rail. Too funny. Also found with injection.
Hi adamant it iv got a MacBook Air a1369 when I plug in the Mac turns on d see straight away showing white screen and chimes every couple of seconds any idea what this could be please 😊😊
Come on…. no capacitor, no shorted capacitor!!!
Nice to see that other companies fail other than Apple lol. Everyone seems to make it seem that only Apple makes tech that fails. Oh well. Let’s see more fixes for everything which is useful.
Great video. In South Africa we still fix them and use these laptops. New decent laptops are really expensive here
Depending on the generation of the i3 it could be worth adding a cheap 4GB stick and an SSD. I have souped up worse potatoes for the £50 that would cost. We all tend to have much higher expectations than someone who has happily used this for email, word processing and a bit of internet browsing. They aren't expecting Cyberpunk 2077 at 60 fps.
I think you may have misspoken about the CMOS battery going into a diode, causing further drop. I believe the CMOS battery is directly attached to the RTC (Real Time Clock) with no diode is series. Any switchover is done internally in the RTC chip. I looked at an offering from NXP and it can accept 1.2 to ~ 5 V. on the battery pin. Nothing wrong with changing the battery, but it probably has a lot more useful life as you were measuring it under load and with the load of the meter. Anyway, thanks for all your useful videos.
sparten I thought the word was sparce
cmos batteries are supposed to be 3 volts so I don't think the battery was flat
if there was no power did you check the mains adapter first to make sure that was working
