** Update ** this tablet worked fine for about a week and as long as you always keep it plugged in when not in use would probably be fine, but eventually I let the battery get low and sure enough it did the same thing where it let the battery be drawn down below the cutoff voltage... Since It was still within the 30 day return period I sent it back to amazon and have since decided that Chromebooks are much more useful than android tablets anyway ;) But it was some sort of hardware failure to be sure. Could be just the battery or it could be something wrong on the tablet motherboard PCB. Hard to tell.
How to fix the tablet if the battery goes below 3 volts and needs to be recharged by an external charger
Thank you Chester.
Nothing worked in my case, your way worked fine. Brilliant engineer.
This method works for my Tab S. I have tried pressing switches in all combinations and many times but no luck. I opened it and measured the battery pack freeze at 3.26V for long time even it was plug in charge cable. I used a camera battery charger to charge it directly up to 3.7V and then re-pack everything. After several hours charging with original Samsung charger, it waked up when I just push On-Off button only. Now it is still charging at 30% with normal screen as it " deep sleep" before. Thank you Chester Lowrey.
Just did this. I was skeptical because I really had no indication that this was the problem, I just knew that my tablet wouldn't turn on. I ordered the part and charged it for 3 minutes. The screen turned on and I was able to charge it fully. Thanks!
Thanks Chester! Worked like a charm. Saved my Samsung Tab from the scrap heap.
Thanx my man, i've got 2 "dead" ones as a gift, ive tried your method, battery was at 1.8V, charged it to 3.5 and it started charging and turned on! now checking second one
Here for dropping some Kudos. I just got my display to finally turn on with your trick! Charging atm and just happy to see this thing come back to life. Thank you!
also for anyone else: After getting my device back on I realized it was drawing a lot of power and draining the battery quickly. Also no wifi or bluetooth. So I went to this guys video. ua-cam.com/video/kfImOrZV-jQ/v-deo.html The bluetooth chip is fried and causing the issue. So I will try a replacement based on this the above tutorial.
Awesome! Used this method and a jury-rigged 18650 battery charger to boost both batteries on a dead SM-T805 to 5V and brought it back to life! Charging now at 20%. Total cost $0. ..😋😋😋 . !! Thank you so much!!
You just helped me pay my bills, thanks
If you don't have that little part you can always cut off the end of a usb cable and use the two power wires (usually black and red). Just make sure you use them carefully and check the voltage as a usb cable runs at 5 volts and will not have any over-charge limit. My cells were at 2.8v, I tapped the contacts for about 15 seconds, they got up to 3.15v and started charging again :).
if my battery reads 3.8v where you are charging from but only reads 1.5 between read and black terminal is do I need a new battery? or what's fried on it plz
I used a USB cable connected to a AC Adapter or notebook USB port to charge the battery. After 5 minutes charging it reached 3.5V (2.7v before) and started to charge from the Galaxy tab dock. Thank you!
thank you! its works for me
i want to take out the battery itself and solder the cable on the mainboard.. where the 2 red and black wires connect on the mainboard. i tried it but somehow didnt work.. if i take out the battery the t525 similar to yours, starts and reboots all the time, but download mode works fine.. without the battery only with cable connected to microusb..
hi
i already did charged the batt using usb pcb board..
now the batt has the voltage up to 3.6vdc..
and i do check on the batt connector and it shows the same volts..
but i still can’t turn the tab on..
is there any missing step..
pls help..
Hello Chester I have the GT N8000 Samsung Galaxy Note 10.1(2012)I believe it has the same problem. It workes fine if I charge the battery in another tab but charging it directly it doesn't take in any charge. I replaced charger, battery and charging port but still won't charge. Please assist.
have you ever tried this with a kindle fire?
I'm doing this for the P7500 model of Samsung tablet. The batteries are 3.7 Volts. I sit ok to charge them with the circuit board that outputs 4.2Volts ?
Yes, most lithium ion batteries are 3.6v or 3.7v nominal but charge at 4.2v so you should be fine.
Thank u very much chester😃😃😃 my tab is now at 16%
Where can i buy this magnetic cable?
cool trick. Can you provide the link for the charger and the magnets? I would like to get those. Hopefully, I can find it myself, but a little help. If I can't find it.
Worked well as described on my Samsung tablet. Opened my 2.5 year old tablet, disconnected battery, charged at 2 amps for 1/4 hour, reassembled, then could use the tablet' to fully charge itself. Now works as it should. Samsung Support Center had asked 150 British Pounds to repair it !!!!!!!! Thanks
where did you find the cables can you provide the link
On Ebay search for "tp4056 charger usb"
Link for the charger and magnets? Thanks
And what about your tablet SM-T805 does actually charge the battery but the power on button is (must be) broken so you cannot turn it on? Method below "If your device is frozen and unresponsive, press and hold the Power button and the Volume Down button simultaneously for more than 7 seconds to restart it" is not valid since the Power button itself does not work :(
Ideas?
You would have to replace the button PCB most likely - but it could be other issues I am not sure..
i cant seem to charge my tablet its the gt n8000. The tablet wont charge nor turn on.... i tried to clean unplug and replug the battery and its flex cable also tried to charge it for days. Still nothing😥. No hope at all
Hi, I want to do this but I'm wondering if it could work with the regular charger, if I just cut an old usb cable, plug it to the charger and connect the re and black wires to the battery? Will it work? What does this circuit board provides more than the regular charger,
No I don't think that will work. If by "USB charger" you mean a 5v USB power supply like what comes with the phone. Even though these are commonly referred to as "usb chargers" etc they are not actually chargers at all but just a 5V power supply. A real charger will regulate the current and voltage specifically for a lithium ion battery which must not go over 4.2v. The USB power supply will try to deliver as much current as it can and 5V directly. In a normal phone the actual charger circuitry to regulate battery voltage and current is built into the motherboard. Most likely the power supply would go into over current shutdown mode. Either way it's not safe and could damage the USB power supply or the battery.
Chester Lowrey
Thanks, I just ordered that little circuit board, I'm wondering, did you plug it to your computer usb port or to the usb charger?
I plugged it into the USB charger (technically a USB power supply) because the charger can deliver at least 1A of current, some older computer USB ports are only designed to provide 500MA but some of the newer ones provide 1A of current. Your phone built in charger is smart enough to tell the difference and only use the current that the port is designed to provide. The cheap $2 chargers from Ebay do not have any way to tell, and will always try to use the max of 1A current. So it is safer to always plug them into a real external USB charger. Hope your tablet is fixable :)
Chester Lowrey
Thanks I have the 350mA charger that came with the tablet but I also have one that outputs 2A from another Asus tablet, I might use this one.
I had a similar fault with my SM-T800 10.5 Tab S and discovered it had simply frozen and was brought back to life using the following reset instruction as per the user manual.
"If your device is frozen and unresponsive, press and hold the Power button and the Volume
Down button simultaneously for more than 7 seconds to restart it.
- Type 1 (SM-T800):
that may work in some cases but definitely not for my tablets particular problem, I tried all possible button combinations first before delving into opening the case.
Mike Kay, you save my life thank you it works !!!
Mike Kay 😭😭😭 thank you! It worked!
worked for me
worked :)
Hi! I’m trying to revive an old tablet of mine but I think the charger port may be messed up. This method seems like my last hope. I searched TP4056 charger on Amazon but I do not believe it comes with the red and blue wires as shown in the video. Is that something I have to buy separately? If so, what is it called?
I soldered the red and black wires to the charger - you may be able to find one with some wires already attached though.
Chester, have you ever encountered an issue where the logo screen flashes off and on? I've got a Galaxy Tab pro SM T900 that is now off warranty, and I've tried all the soft reset suggestions I've found on forums. I'm beginning to think it's something inside the tablet itself. Any suggestions?
Never experienced that on an Android device.. Id guess something to do with hardware in the tablet also. Maybe replacing the battery would help but I dont know for sure..
Thanks, Chester. I contacted Samsung, they recommended that I send it back, because it sounded like a hardware issue to them.
I did exactly what you did and my tab still won't turn onit was just a day ago my tab was working fine. Wake up and started using it and plugged charger in and it wouldn't charge. The notification battery charging symbol came on but battery % was dropping .
So I directly connected to the circuit board exactly like you did and nothing .
Could it be possible that the port it's self
Could be the issue . Say if the charger I was using pushed the pins out of place or possibly rearranged them and now
One of them is touching.
Hmm yeah it could be lots of things. If you have a multimeter you can measure the voltage on the battery to see if it's good. Or try to look into the micro USB port and see if the pins look messed up.
which source are u connecting to the usb circuit board to charge the batter - is it a power bank ? please give details ? i have the same issue , i am from india , service center asking for 170 usd [Rs100000] for replacing the system board . i bought and used for sometime and the put back in storage but when i took it out after a month or two - it was dead - please help clarify
You can connect it to a USB power supply, computer, power bank. any usb port should work
vrdommed bro i know this isnt relevant but u added a extra cyber to the rupees
Hi. my tab S takes such a long time to charge up even when using a fast charger plug. Is there a reason for this?
I'm not sure.. Some of these older tablets need the exact charger/cable they originally came with to fast charge, otherwise they only charge at 500ma.
what is the part you are using to charge the battery up with ?
www.ebay.com/p/5V-Micro-USB-1A-18650-Lithium-Battery-Charging-Board-Charger-Module-DX/1844136656?_trksid=p2047675.m4097.l9055
Mine shows 99% charged and then 100% right away when a charger is plugged in. However, it does not boot up. Where do you get the red and black wire and magnets?
I think in your case you need to order a new battery. The magnets can be found on Ebay by searching for Neodymium Magnet - any small size will work. For the wire search for 20AWG Silicone Wire
Couldn't you just cut a USB cable and connect the black and red wires
from that directly to the battery, using your normal wall charger?
In other words, why is the battery charger necessary?
Solid State no you cannot just connect a USB cable power leads directly to any battery without a charging circuit between them. All devices that use USB to charge have this circuit built into them. but if you connect the wires directly to the battery like this you bypass the charging circuit and would overcharge your battery or overcurrent the USB power supply. technically the devices everyone called "USB charger" for their phone is not actually a charger at all but a 5V USB power supply.
Ok, thanks mate!
hi
i have this exact same tablet. my problem is that i keep getting a weak charging error message. the battery will not maintain charge even if i leave it on its wall charger while using it. while it does take hours to drain (and therefore still useful to me) it will not charge up even if left plugged into the wall while using it. it used to charge up slowly when plugged in and being used. is there a way to restore this battery to its original working condition?
Sounds like the battery has failed and must be replaced, I have not done this personally but it looks like there are other videos here on UA-cam showing you how.
Chester Lowrey
Does the part come with the wires ?
No it does not come with wires - you could steal wires from some other broken device or buy the type I used - Silicone 20AWG wire - it is very flexible and nice wire. You will need some type of soldering iron to do it the right way - but I suppose in a pinch you could just twist the wires around the holes in the PCB and it should work.
I was trying to get my tab 3 working When I finally got it running I noticed there was no sd card. I lost my sd card. I had it in the slot. Where did it go? Pleas help!
Wow. You want a youtuber to help you find your SD card that you dropped somewhere? Are you serious?
bro my tab s2 is wont turn on.. its happen after i play a game and the tablet is frozen.. after that the screen is flickering in off condition
Man I just blew out the power button nob, had back off and drained motherboard by holding power button in and tried jt a few times and when I let go the power button nob is stuck down now
So guess I'll need a new power and volume levels strip?
Man this sucks I have family pictures on it and near end of month will be two years since my mom passed from cancer, now the power button is blown or stuck down, what can I do?
God Bless
I have ordered everything unfortunately the cable wires were too large. can you provide a link for the red and black cables, please
If you search on Ebay(or elsewhere) for silicone wire 20AWG you will find one that will work. - If I provide links they will just be out dated in time ;)
Chester Lowrey I have been unable to locate the wires. can you post a link for me
hey i have the same tablet but my when i plug it in won't charge but stays on you can use it normal but on usb and when i unplug the usb it goes off what do u think is the problem the battry is dead ? i need your help guys
Yeah sounds like the battery is dead, I would buy a replacement on Ebay.
My tab s 10.5 slipped out of my hand and now the touch is not working and some colours have vanished from the screen what do I do
Using rubber globes next time!
Can you post a link where to buy charger on Ebay?
Search on ebay for "tp4056 charger" and you will find lots
i had a prob with my samsung gt p7500 10.1 tab.. it won’t turn on and it’s not charging as well.
my question is what if i use normal usb cable and samsung charger instead of buying those dongle. is it ok.is there any prob to my battery pack.
You cannot connect 5V from samsung charger directly to battery. You need the pcb charger to limit to current and voltage to 4.2V 500ma.
Chester Lowrey thanks for the info..
My tab s fell from a height and now it is not turning on what should I do
Hey Chester this model of tablet has been having an issue where the back button and menu button go out but the home button still works. Have you found a solution for this?
+Alex Pichot Nope sorry I dont know how to fix that but would guess the capacitive touch buttons have failed, you may be able to replace just that part but I did not take apart the screen enough to tell.
+Chester Lowrey Hey, do we have to take the sticker out? And..what of it's 0 % and instantly goes to 100% what do we do?
+Chester Lowrey Like..what if the battery burnt and won't work?
+Asriel Dreemurr sounds like you need to buy a new battery on eBay maybe.. but I have no experience with this so can't help you further..
+Chester Lowrey So...how would we put the back of thr tablet on again?
my tablet is fully charged now by this method but still not turning on i tried every power button tricks still no response help!
How many volts must have the battery when finish the charging?
george4a 4.2v when fully charged
+Chester Lowrey thanks now is 4.0volt
Do you have to charge both cells?
Since they are wired in parallel they charge at the same time, they're basically connected together.
I had an issue on my Tab S 8.4 where it wouldn't charge as well,plus bluetooth and WiFi died on me. My solution was to buy a new motherboard and now works perfectly again.
This was bought to replace an old Lenovo tablet which was essentially too sluggish to cope with modern websites. ua-cam.com/users/postUgkxz4qYZoyAOb_hq_UbaKI6AsZX0FnoFm-U This tablet is fast, has a very clear display with built in optional eye comfort shield, great sound with Dolby Atmos, split screen option and numerous tweaks that I've not yet explored. I've plugged a wireless receiver into the i/o socket to connect a mouse if I need it and a bluetooth keyboard works fine - unlike the Lenevo which somehow would often garble the input. Battery life seems good. In short I'm very pleased with it
thanks im gonna try this.... i left my tab in a draw for about a year and now it doesnt turn on and i want to use this tab for a 2nd monitor using a app called supermonitor
just an update ..... it worked but for some reason i had to charge mine to 3.7v until it would come on. thanks bro
What about Samsung galaxy tab s model number SM-T805
Not sure.. it may have the same internal parts, you can also put a new charger inside but I have not tried yet.
I have a tab s too, but it won't turn on. it makes noises and stuff when I push the power button, but the screen won't turn on. if I press the volume button, I can hear the change in volume from the noise that happens, yet the screen still doesn't turn on. It appears everything works, but the screen still doesn't turn on. any ideas?
James Bond yo thanks alot brother i fix my samsung galaxy tab s
My wife doesn't turn off my Samsung tablet and it went flat wouldn't charge at all so I left it on charge for 3 days till it ran hot then unplugged the charger till the Samsung tab s cooled down after a few days ...I put the tablet on charge and wammo it fully charged again,so you can try that fix and see if that helps.
My tablet is having problem when the tablet is shutdown and when I try to charge it doesn't charge it shows battery percentage only and when I charge when the tablet is on it will charge.
Yeah that sounds similar to the problem that was never resolved on mine. I suspect it is actually a hardware problem in the motherboard charge circuitry on this model. One workaround is to never put it to sleep and always plug into power when not in use. Another would be to run wires directly to the battery and permanently solder them to one of these charger IC boards - drill a small hole in the chassis or something and tape the charger to the outside. That way you can always recharge the battery and would be a decent workaround as they are long past the warranty date.
hello my SMt800 suddendly restart .. and restart again to infinite.... i open the backcover to disconnect the battery connector to stop it . After i reconnect the tab restart and 2 min after again loop restart
just 1 min after i reconnect the battery connector , i see that the chipset at the left of the battery connector is really hot ... it was nearly to burn my finger ! can you explain what is the chipset ? maybye this is why the tab reboot and reboot ... i nalso noticed that when i let my finger oin the power button , it doesnt reboot or only after a long time ..... due to the price of this tab i see that i can change the motherboard .. do you think its a good idea or juste wasting money ? thanks for answer ;-)
gerald G. Hi Gerald, I am not sure whether it is worth trying to fix.. up to you maybe can sell for parts?
thanks for quick answer ;-) but i dont want to sell and re buy one expensive samsung( that die avec 3 year .... lol ) i asked this because i see motherboard to buy on chines store ( they are tested and with some guarantee) .. they are app about 50$ .... but what is the function of the chipset on the left about the battery connector ? Gpu ? Cpu ? or other ? ..... this make me angry to buy a good product a lot of $$ and see it dying after 3 years ! this is why i would try to fix it myself :-)
Hi name joe and I bought new battery and push the button but it doesn't go on
Joseph Galling usb port is damaged
Cheers
Lets see if it works
This just happened to my tablett yesterday
What's the name of the charger
+Joseph Galling The charger IC is called TP4056 and you can buy many different chargers using it on Ebay and others for a few $
CHARGER :3 YOUR WELLLLLLLLCOME
+Chester Lowrey it does not work HEEEEELLLLPPPPP
Chester Lowrey Hi this may be a basic question but where did you purchase the wires and magnets you used to connect the charger. is there a amp restriction?
You can find them on Ebay - the current the charger uses is fairly low so most any wire will work.
That relly that really hurts does Samsung battery
Link to where to get the board would be nice. Useless video other wise.
search on Google / Ebay for TP4062 you will find lots. link was further down in the comments.
i have the same issue but instead of pulling it apart I just used a fast charger from a s7 and it charged it no problems. Hope this helps some of you. 👍
I mean a tab e
BATHEDER MY TAP IS NOT CHAGINE POBELEM
Samsung knows these tabs have issues. I have a samsung galaxy tab 2 10.1 wont charge, got a new battery wont charge, now I find the battery on the screen with the circle thing stuck. Ive taken it to many shops, no one knows what the issue is. I called samsung, they want a 225.00 holding fee (whatever that is) then 75.00 to fix it, and no guarantee to get the 225.00 back. No more samsungs
kay Schaeffer yeah this model does seem to have issues..
Sir I need ur help, My Tab Samsung Galaxy 10.1 is not working .When we restart the Tab, Samsung page appear with blue light, that Samsung page still appearing on the tab screen, only audio can be listen , can not see picture please sir it's a request sir please tell me 😓
Did you ever have the SD card get lost inside the machine? I can't find mine. Why does Samsung make the screws so tight? Samsung just needs to put out of business.
Yo hice ésto con una Galaxy Tab S 10.5 Sm-T800 WiFi y funcionó, la tablet no encendía ni cargaba ni nada:
ua-cam.com/video/P03jcPwu0sk/v-deo.html
Desconecté y conecté la batería y ya encendió y hasta el momento funciona todo normal.
6 minutes to get to the damn point..
