I had the same problem in hp laptop. And I found the battery cell is dead completely. The laptop wont turn on cuz the laptop check the ( rtc) line from battery so i soldering an external 3v battery on rtc way and the laptop working but without battery. Until i got new battery. So the problem is the rtc way in some laptop's. Cuz in new laptops the use the main battery as rtc battery to feed the bios
I was thinking exactly the same. BIOS can't store data in memory - probably can be checked by for example changing the date and check if it is not resetting. When there are few reboots on the start some settings like memory speed data etc. should be stored to speed up the boot time on the next turn on.
Charge the battery"s cells to about 3.3 to 3.5v using alligator clips and a current limited 5V power source. Once all cells are at the correct voltage apply a voltage greater than the sum of the pack cells to the battery output wires. Next verify you have voltage at the power terminals. Finally reinstall the battery and charge it up with the power off, next boot the laptop and set up the cmos.❤
Very impressed how you knew where to open the battery to find the fuses. I didn't even realise they had one time fuses in them. It is amazing and also sad how more and more hardware needs software/firmware to fix. Love your work!
The lid sensor theory was actually quite good. I have a lenovo that behaves exactly like that. I have to close the lid as soon as i turn it on for it to stay on. If i leave the lid open, it keeps rebooting even before windows starts loading. There is a magnet on the lid. I put a magnet on top of the scroll lock key (which is where the magnet on the lid rests when it's closed) and that's how i can use the laptop. Sometimes, very rarely the problem goes away (like 1 in 20 times). I've desoldered the hall effect sensor (a simple SOT-23 part) but the problem remained so i just tossed it under the bed. It's a very cheap and slow laptop that's not even worth a repair.
Interesting video Sorin. The whole problem caused by a faulty battery seems incredible and my first thoughts were faulty power switch. Next time I get a laptop with a similar fault I'll remember to check the battery first and I'm off to buy that battery analyser you use, very handy tool to have.
i had the same thought, yesterday. but when i looked at the website where the analyzer is offered and saw i have to pay yearly for a licence to use the unlock function, i abandoned the thought. have a look at the licence price...
Maybe the flux is related to the broken usb port changed? I mean, usb ports seem ok there, probably someone else has worked on the laptop to change the broken one
Balancing the battery in balanced mode. Asus is easy to balance, others are harder. Balancing only happens, when you work below 30%, by checking on the start menu, opening and closing files, renaming, etc. vudeo, games, net, mp3 kills the battery during the balancing process. Only the desktop items must be in use, office or others won’t have positive effect. The battery can go down to 1% hibernation.
I really hope this doesn't become the norm in laptops. Buying a new battery isn't always economical for an older laptop and given that in a lot of cases people keep their laptops connected to a mains outlet all the time, replacing a dead battery might not even be strictly necessary.
Great Job Sorin, a new lesson leaned thank you very much, very bad obsolescence programmed... bye Francesco Timpano from florence Italy @Timpano Francesco Repair
❤ so this says also that when we have a dead battery, we should check if it is really used or locked, and find a strategy to make it working. I had a similar issue with my tablet, I changed the battery because suddenly it was not charging, saying non sense about the charging state an what I was able to measure. I put a noname battery, without any circuit only + and - and driven directly a recharge. Since works fine. This is programmed obsolescense 1000% out of folowing Sorin😊
On this battery one of the cells which located near the cooling fan is heated more then others. It causes excessive self discharge rate in comparison to cooler cells. Also it could cause chemistry degradation if cell gets too hot. Sometimes it is enough to inject into such cells extra charge so their voltage is up to 30mV leading above other cells. It will compensate increased selfdischarge rate for some period and let the battery to be in service. p.s. On the video lagging cell was not fully balanced and still have big voltage difference. It could cause same issue to be happened.
@@einfelder8262 would like to believe but PCBs and battery are strange creatures, they develop shorts and unexpected failure when you drop things. I have seen battery's loose charge suddenly for no reason, particularly old batteries.
Hello master nice video.. but what i know, u must set the clock at bios with a right time and calendar.. if u not set the clock and calendar with a right time and calendar, the laptop will auto on sir..
I guess the battery replacement is still in order. And man I can't believe that modern laptops won't work without the battery present... The old laptops didn't have this problem.
Miss the old days where electronic faults were logical and not proprietary firmware related... Looks like soon enough we won't be able to fix much because of expensive equipment needed to analise simple faults like this.. dead battery should not impair laptop functionality beyond beeing charger bound..
Seems like all these Asus Zenbooks have the same problem with the battery fuse. I recently got similiar Asus Zenbook UX425UA, symptoms were almost the same, but i could get the laptop to work without battery at all, so I knew i had to replace it, when i did, the issue was gone. I am just surprised that in your case it didn't work without battery connected.
The battery-analyzer is a good product, but indeed a bit expensive. It becomes way more expensive because you need to have a yearly subscription to unlock batteries that is a seperate option ($269 per year, or $399 for 2 years or $999 for 10 years, and that's excl. VAT). So it's only worth it if you repair batteries regularly). I found out after I ordered it and only had a 10 day free battery unlock option...
@@levendlicht The subscription is the cheapest on the market. When you say it is expensive, justify with other cheaper products. Take into consideration that NLBA1 offers free fast support directly from manufacturer's experts.
I don't want such feature/bug, as they might selectively set based on power cycle and make the laptop stop working just like they do with printer cartridge.
OS like windows can tell you this by the data about difference between original capacity and the current one. Few years ago lot of people complained about this kind of notification. I guess currently in Windows it's either hidden or turned off.
❤I have tree ipad like that standing me to find a solution. They broken the screen , not a big issue to repair as the ipads are working fine after a manual inside charge, but so, they are locked .Seems some repair shop send them directly to the garbage can...
The battery died from usage. That cycle count was pretty high. Im guessing the customer uses that laptop with the same mentality as they use a cell phone.
The battery is now dangerous because it's protection has been bypassed. I would advise the customer that he can only get the device back without the battery installed.
14:54 hi Sorin. Look, i change 3 cells 3.7v from an Asus bateries, always i make this kind of job on celphones (one cell) and tamblets (2 cells) but on a 3 cells controler, it kips on look state. Can be posible interchange 3 cells controlers and make it wotk without that hardware analizer? Thanks, i following you sinze 2.000 subs! Fron Patagonia, El Bolsón.
I would have understood if the motherboard was locking the battery to prevent it from being damaged with high current or anything, but this was definitely not the case with this dying battery. This had the feeling of greed from Asus: battery has done it's cycles, lets call it a day and pretend the whole laptop is on the end of his life, which is insane ...
Reflowed CPU? You are either insane or completely clueless. People don't just randomly reflow the CPU. Well they could if they want to permanently break the laptop and instantly turn it into ewaste lol
Why do people tell stories about the problems with the laptop. Imagine going to a doctor and making up some story about what problems you are having... How are they supposed to help you? Maybe it was drawing current and the fuse blew (hot metal flows with impact) when they dropped it?
so you diss people for making up a story then go ahead and do exactly that making up another story without any clue about the actual problem "maybe it was drawing current and the fuse blew" etc. Funny LOL!

rtc line would be the white wires on the battery connector, yes? would you not need to unlock the battery with the software if you did this trick?
I can't believe you fix it !!!
It's diagnosed, not fixed, until a new battery goes in.
Charge the battery"s cells to about 3.3 to 3.5v using alligator clips and a current limited 5V power source.

Thanks and well done like alwaya Sorin😊😊
Watching your videos, it is possible to make a ranking of repairerability of modern day laptops.
👌Thank you for sharing.
Some Asus batteries have RTC pin which supplies 3.3v to the Bios clocks. So missing RTC voltage could cause described issue.
❤This is to think about sure. Like in the old time!
what? you can't power the laptop with just the charger?! So bypass is now a feature?😤😤 since when this started happening?
Battery Analizer quite expensive, but it paid off if your are A battery Repair expert
If the price of 3-4 genuine is high, then yes, this tester is expensive.

It would be great if ASUS or any company had a pop up mesaage in bios saying: "REPLACE BATTERY".
dell man it saying

Dell e6000 series does that and also lists the wattage adapter in use
good video thanks:)
Not many laptops can survive a drop, but this battery issue reminds me of how apple does things, locking down the hardware forcing ppl to spend more.

I'm really enjoying your channel!! Could you tell us what kind of bench top power supply you're using?
nice one...👏👏👏
Nice one
I encountered this kind of fault two weeks ago. But that was acer, this one is asus.
When he says there is NO SHORT it means the circuit is good or bad? please help me understand
Well, now we know these "tech" companies will strive to screw the customer. Thank you Very Much, Sorin!

Hello🤝crazy🤯good job👍👍👍👍👍👏👏👏👏👏👋👋👋👋👋👋
Sorin, I was wondering if you're going to plug a new fuse into the battery?
But where is the broken usb port?

Laptop drop ...some time later stops working... blame the drop but really just coincidence
There companies can’t survive without planned obsolescence lol
maybe they reflowed cpu since it gets hot, the thermal paste application says it all

What a stupid laptop. How it is dead when battery is dead... Ridiculous. Negative for Asus.
