How to jumpstart an iPad - (PWJ175) 

Nice video, but i waiting for the mid-roll ad, mid ad ad roll, wont be long before RU-vid puts ad's in ad's. I had a Lipo battery that a charger would not charge as the voltage was too low, so I connected a power supply with a 100uA limit and just left it. The voltage slowly came up and then the charger charged it normally and it recovered full capacity.

240v usually does the trick but for a very short time then they go BOOM!

Good video, thanks. I use my older iPads (wifi) as semi permanently positioned media players, camera monitors, timer/clock/alarm,or for web searches.

great vid!

Pure engineering!

that loading intro screen :)

@Play with Junk - for 5 Volt I would just use one of my old computer power suppies I have lieing aroung

well they would have bee usefull with Android but since it is apple you can pretty much trow them in the binn exept for music / picture viewing. Maby some monitoring uses. ( Then again i dont know if apple supports the software)

I had a similar problem with the original Lenovo Thinkpad Tablet with Android. If the battery was really empty, it would neither boot nor charge. Fortunately, this device also has a 20V charging port via the docking station. If you use that one it will charge even from an empty battery.

Have a 1 yr old iPad Pro, accidentally ran the battery completely down. Could not get it to charge or power on. Was still on warranty so took to Best Buy. They replaced it. Nuts.

This video helped me to damage my battery. Thanks lot

What I would love to see is a video where someone figures our how to either drill a hole to jump start them or even designing a template that would allow you to carefully use a drimmel tool and cut through the back to get to the battery (avoiding screen removal).

I had a couple of dead PS4 Dualshock4's (well the batteries). Registered 0v both in and out of the device. "Jump started" them by putting 3.6V directly across the terminals and waiting... slowly rose to 4V(ish) from 3Vish after a couple of hours... no problems since. Issue is that they have circuit protection on the battery and if they get to low (they had sat unused for some time at my lads) they won't charge in the dualshock and they cut all output power as well (hence 0V). Probs not a good long term solution (I believe that under volting can damage the internal structure and that force charging can make it a whole lot worse) but works for now till I can be bothered to get new batteries.

Great video. Sadly my cells are totally dead. Is there any way of running the iPad without cells, e.g. by connecting a 4V power supply directly to the contacts of the battery controller board? How would that need to be wired? Just connect both - and + together and then feed 4V into the 2 wires?

Can I charge the battery in an other way also ? Because I don’t have a power converter?

Cool video, but the iPad 1st generation that i saw in Sweden couldn’t start because the battery won’t work and it was completely dead battery and it didn’t charge. The iPad 1st generation that i saw in Sweden needs new battery and charge.

For my iPad 3G the screen just flashes every few seconds. The battery is flat. Do you think that’s the same issue?

I had similar iPad woes, I hooked battery direct to power for a few minutes and got a result then used USB to charge it, but the screen remains black with a glow from the backlight only. It is found by PC and able to be restored but still a blank screen. Any thoughts, I have checked all connections, several times and suspect lcd issues. Do you agree?

No prob, I have an ipad, a1337(1st gen, yeah a dinosaur). I'm fixing to charge the battery bypassing everything. It doesn't look like it has been damaged. Îs this a good or bad idea

what are those hooked probes called? They are awesome!

I suspect there's a reason why they won't charge over-dicharged Li-Poly batteries: they build up internal resistence in overcharged state. With time, the resistence grows to levels high enough to disperse charging current as heat between the battery's rolled-up foil, melting the insulator and shorting the foils together. The battery puffs up and may rupture.

I would glue them all to the wall and make a photo wall or an esoteric rgb cluster lamp :D

I hope someday we will be able to put Linux Kernal booting on all old waste and repurpose them for something usable for the lease as an embedded computer/microcontroller. After a span of a decade from when the company killed the product, they should release the tools in the public domain so that the devices can be repurposed. It will reduce the sheer amount of e-waste we generate every year. Just a thought Cheers!!

I'd be awfully tempted to measure out the location of where that insulation you removed is and use a CNC router to drill some very small holes to the battery contacts; press in some sharp pins to make contact, jumpstart, fix holes with dot of superglue.

Thanks for sharing! I managed to work through all the steps pretty well and charged the battery to 1,5V but after reconnecting everything the display remains black. Any suggestions?

Holy crap, that's at least 12 mid roll ads. WTF RU-vid

I had a quick look around to see if there was a linux you could install...too much proprietary hardware for anything usable from what I see. I think you have land fill, unless you can use the screen/touch screen and batteries with other hardware - a RPi4 perhaps?

If you leave this on the charger for several days. It should trickle charge itself back to life. When it says :not charging: it is charging at 100 mA So. Overnight. Youll get a nearly full charge with the screen off.

Even my iPad 1 is updated to iOS 5.1.1

Great video. This is why I refuse to buy Crapple products. They are deliberately designed to fail, and if that doesn't happen fast enough for their quarterly sales projections they infect old devices with an update...

It's a great feature. It ensures you will buy a nice fresh Ipad. You don't get a market capitalization of 2.155T with durable, easily-serviced products.

The plan of the unit is this, they do not want you in there.

Does this process erase all your data?

OMG wie viel wollt Ihr für ein Ipad 1? Ich wollte immer schon mal eines haben und selbst wenn es nur Deko ist!

nice :)

I've herd that sometimes some issue with the operating system or application will cause an Apple device to crash. When the device is rebooted the problem is still there, causing it to crash again, forever.

I once went through 3 LCD screens trying to repair my Samsung s5, I think once these devices get to the micro scale and glue involved they're nearly completely un serviceable

I think the sample rate of this video is weird - your voice and the intro music both sound about a semitone lower than usual. 44.1/48kHz conversion issue, maybe

Also, worst-case, you have a nice chopping board.

Are you sure it's not some boot-loop (software) problem?

Also, let me add……….Very important for me to use authentic Apple power supply And cord.

firewire?

Easy why hair dry the back

Me, sweating violently doing this with a fucking wall plug and hacked up USB cable, unplugging every few minutes to check the voltage. Edit: Somehow it worked and nothing exploded phew. Lithium Ion packs are WEIRD

This is the reason I quit buying apple products. 🤮 apple 1 tablet sucks.

Vertically integrated overpriced under-supported junk.

Modern technology is so wasteful
