Help tab 10.1 will not turn on :/

[RobDickson]

Wow, you've changed your tune a bit! Two weeks ago, you said "It turns out that mostly I've been holding the power button down too long", but now you've said "my unit (and probably many of yours out there) has a power issue.". What's changed your mind?

Silly question, but if you don't like Best Buy's prices and support, why do you buy from it? I'm no expert, but offering to upgrade the firmware for a customer sounds like pretty good service to me.

 

[jpb1818]

I agree with cyphire. Best Buy sucks, and I stopped doing business with them in 2006. No customer service at all, whatsoever.

My tab just stopped powering up. It did this once before and I was able to power it back up with the power and screen-touch combination, but I've now tried everything and absolutely cannot get it to power up. Taking it back to exchange it tomorrow.

I've had my tab for about three weeks now and its already had the problem of not switching on about twice so far. Holding down the power button for 12secs seems to work but since its still under warranty i'm wondering if its worth sending back and getting fixed?

I exchanged mine for a new one and i'm glad i did. My new one is the exact same model number, but has a different software load. It has more options than the last one, and the setup menu is entirely different. had it for 5 days now and it powers up every time with only a 2 second hold of the power button. I would suggest taking it back and swapping it out...

 

[RobDickson]

Returning your tab just to get the software upgraded seems a bit over the top.

+1
all of the above.
Me too.
Have to press the power button for 10+ seconds to get it to turn on when I thought it was just sleeping.Then of course it does a full reboot.
Kind of embarassing because it happens mostly when I am trying to show off.

I wonder if the firmware is different on your old one and new one. Did you ever run the updates for the tablet? There has been at least two major updates:

Produce release: Original version 3.1 vanilla Android

Update 1: Android version 3.1 with TouchWiz added to firmware

Update 2: Android version 3.2 with TouchWiz included

I was on v3.1 with TouchWiz when I bought it. I never had a power issue. I found the v3.2 update, reset my Tab, updated, then reset again to start fresh. I've never had a power issue with this version either.

I'm wondering if the issue is hardware specific or software?

I'm using the 3G model (P7500).

 

[normanfinks]

i have a p7500 for a few months. twice it has not come on when pressed on, dead...then after some time, the last time, days later suddenly it responded! What to do?

 

[lgHaole]

Found on another thread: press and hold the power button while touching the screen. May take up to 30 seconds.

Worked for me, Tab suddenly wouldnt come on or charge after working flawlessly since the day it came out.

No clue why the above works.

Brilliant!! I was ready to take my Tab in when I did a quick search and found this ... worked for me after 10 seconds. Weird as hell though ...

 

[ckelly33]

Mine locked up. Now after doing the power/volum key trick, I am getting an android "Downloading" screen.

Anyone else see this? It's been downloading for quite a while.

[smpcorp]

Thank you! It worked!! I thought I would have to send it back for repair. Samsung is a wierd bird. My Galaxy Epic is almost as strange the way it changes settings all by itself.

 

[sdtag]

DAMMIT!
I just got a replacement tab from Amazon. I thought it was better. It just did it. I pressed the power button for a split second to turn off the screen then 10 mins later when I tried to wake it up I had to eventually reboot it.
I am thinking about returning it for a refund now. For this kind of money I can get a full on laptop. I am getting discouraged now and pissed off too.

 

[Bigjacq]

I can't say why it worked either, but the combination of volume/power button did the trick for me - tablet is back and running. Thx!

 

[suzanne861]

Thank you so much, the touch screen and hold down power worked for me

Used my new tab last thing before going to bed last night. Wake up today, and it won't power on. Tried plugging in charger and to computer to no avail. Anyone have any ideas?

OK now for the sure fire way of resetting your Tab 10.1. After everything has been tried and all the helpful comments have not found a fix, there is an engineering way to reset your Tab 10.1.

What keeps the Tab 10.1 from resetting is actually a full or partially full battery. The battery keeps all the memory (cache-little chip memories) refreshed in a false state (that is why you cannot generally do a successful reset by all the methods below!

So the fix: let the battery fully discharge...this will reset all the hardware and software parameters (clean out those little caches) and push the Tab into a soft reset (you should not lose any data) . Then reconnect the battery charger and you will see the battery recharging - leave charging for at least 2 hours). The hard part is to fully discharge the battery (this can take several days if you have no way to discharge the battery) I used the samsung keyboard, without it connected to a power source..this slowly drained the battery...when the battery is fully discharged reconnect the power source (after a few moments the battery icon should come on charging) - I waited for 1 hour on charge and everything came back to life..and now my Tab 10,1 is working perfectly again

I am a professional Engineer...that became frustrated...so tried the old battery discharge trick! Good luck

So the fix: let the battery fully discharge

Just one small problem with that "fix" - Lithium-Ion batteries never fully discharge because they have an integrated IC that monitors the charge and discharge rates, current, voltage, charge level, etc. The IC prevents the battery from being fully discharged like NiCad or NiMH batteries. So even though the battery level may show "0%", the battery still has some charge to prevent the IC from cutting off the juice. I doubt your results were due to the battery being discharged, but rather the device powering down and back on again just like using the power button.

Also note that the worst thing to do to a Li-Ion battery is to fully discharge them. Li-Ion works best when topped up and they do not have any memory effect like NiCad does. The lowest I even let my batteries go in my phones, tablets, laptops, is about 40%. If I get that low, I either put it on charge, or if there is no available place to charge, I turn the device off to save power until I can get to a charger. You Li-Ion battery will last much longer and with greater capacity if you keep it in the top half of the charge level 50-100% all the time.

[RobDickson]

Kinda like [insert your favorite Star Trek captain] saying,

 

[Thorsten]

You mean there's any other choice apart from Captain Kirk?

Yes.

I actually do like the captains from what I

 

[Cazzie01]

Thanks tablet up and running.

 

[TechPorVida]

I had the exact same heart-stopping issue just an hour ago. As LaTuFu suggests, plug it in for a couple of hours. Hold the power button down for 15 secs (other members report holding it as long as 3 minutes) That worked for me, hope it works for you. Best

 

[Superkidsnurse]

My tablet has the above issues and NONE OF THE ABOVE has helped. I strongly believe that it is the firmware. If I can upldate the software using a dos program then I may be able to update the firmware. I cannot do it any other way. ODIN doesn't recognize it- nor does Kies.
Anyone have any idea???

Mine happened this morning, after updating my tablet, on wifi, and after installing it, my tablet wont turn on. I get as far as the samsung word coming on for a second or two before going off... I've tried everything and nothing works =/

 

[Braddles]

I've had this happen twice with my tablet.
I've had it a few weeks now & I power it down at night knowing I won't use it till I return home the next after noon.
When I go to power it up I get nothing. So I plug the charger in & instead of the battery charging animation I get a battery picture with a red line saying it's empty? There is also a yellow triangular road hazard type sign??
Does this mean I have a problem worth chasing with warranty?
I bought the tablet from a store that has since gone into liquidation so I will have to deal with Samsung Aust direct.
