Chosen Solution

Hi. I have a Lenovo Tab A7-10 My tablet is less than a month old. My problem : I can not switch on. The tablet keeps vibrating and showing the Lenovo boot screen and screen goes back to black and start all over again. I tried many methods including the 20 secs power button. Or plugging the tablet for quite some time. Only to see the same results. Any help ? Thx.

If the tablet is less than a month old take it back to get it fixed under warranty

I had this same boot loop issue happening numerous times with my Lenovo Tab 2 A7-10 (brought in France in August 2015), even few months after buying it. At first I tried to disconnect/reconnect the battery but this method never worked. It seems the external SD card is the culprit (it seems to pump the amount of energy it need to properly boot) Here is the working method I use each time :

  1. Remove the SD card
  2. Connect the USB to charger
  3. Normally, the tablet will vibrate, then show Lenovo logo, then show the battery level.
  4. Wait till battery is charged at least at 5%
  5. Power on the tablet. Hope this will help. The main issue is that the tablet is vibrating and starting when the USB connector is plugged, which is a bad design as this drains more battery power than the USB power can load the battery during the same time. It should be able to just refuel when connecting the USB cable, without powering it up.

have this problem with 2 of these tablets . whats happening as far as I can see is that they seem to try and boot up as soon as you plug power in…which is great except when the battery is at 0%, so they start to boot , read that the battery is 0% vibrate and shutdown , which drains whatever power the battery had received by charge , it then starts to get a charge , detects this and then starts up again , and so on ..which means its stuck in a loop that never really gets it enough charge . What I found worked was to hold volume down and power for about 10 seconds , it’ll still try and boot , and fail , but usually this gives it enough charge to start up enough to actually get past the boot screen and start the charging process properly(it’ll show a battery at 0% and start charging) .It can take a few goes to get this but it should work .

Just press reset button and press power button..if you cant find the reset button just open the back cover en then you can press it with finger… Good luck

Hope this helps: Remove the back cover by prying it out.Disconnect the battery connector carefully, and connect it back.Replace the back cover and connect to charger. When it has at least 5% charge, power it on. To avoid the same happening again, don’t try to power the tablet on when the battery is completely discharged. If the battery is near its end of usable life, replace it with a new one.

help me boot repair plz……….

I have the same problem, but have disconnected the battery and then connected again. Still have same problem. As soon as I plug in charger the screen comes up with Lenovo Logo powered by android then restarts. Any help would be greatly appreciated

worked perfect reset with button and power..Thanks

Hi, I tried all the ones mentioned in the thread, but what worked out was changing the cord. I looked for the original cord that was together with my tablet. :)

It seems that you don’t use the original charger, like a phone charger, which don’t provide enough power to start the tablet.

hello I know that this post is a little old now, but i found a fix that helped me alot. firstly you disconnect the ribboncable to the screen and the ribbon cable to the sd card slot. after that you should just keep it charging for about 5 minutes, and then hold down the startbutton. after you hear the boot sound, you can connect the ribboncables again, and let it charge some more. (P.S. I dont know if this works for you, but it worked for me on 2 tablets which had the same problem).
