Lenovo ideatab s2109 screen flashes while usb charger is used

I lost my a/c adapter that charges my tablet. The user manual indicates that I can use a USB charging cable plugged into my computer. The screen usually displays the charging icon but this time the tablet sounds like it is trying to charge but does not. Just flashes "Lenovo" and seems to turn on and off by itself whilst attempting to charge. What happened to my tablet. It was working fine before the battery ran low.

SOURCE: Battery not charging

how long has it been since the batt was purchased? usually batteries are considered consumable parts. meaning in due time, performance will degrade, laptop batteries should be good for 1-2 yrs, after that it battery hold will degrade. also check your ac adapter, try removing the batt, and turn the system on. if the system works without the batt. then it might be the batt itself thats having issues...

confirm that the Power adapter is ok if the A/C indicator comes ON on the LCD on the laptop. If the A/c indicator is off replace the the power pack. Else the board may be bad, replace the board.

Frequent Charging Shortens Battery Life Frequent charging shortens the life span of a Lithium ion battery. Batteries should be charged only after they expend all their power. b> Switching Batteries Switching batteries helps preserve battery life: If a cell phone or computer user puts in a spare battery while separately charging the primary Lithium ion battery, that helps extend the life of both batteries. b> Removing Batteries Most laptops charge the battery when a user plugs in the AC adapter. Users can adjust this setting by changing the power options. Windows places this option in the Control Panel, while the Gnome Linux desktop places power options under "Administrative Tools". Cell phones incorporate their own power-saving features that the user usually cannot control. b> When to Replace a Lithium Ion Battery If a laptop battery does not hold a charge for more than a few minutes, a user must replace the Lithium ion battery if he wants to use the computer without an AC adapter. Other Ways to Extend Battery Life Storing a battery in a cool, dry environment causes a lithium-ion battery to last a little longer and reduces the frequency of needed battery replacements. Hope this helps.

I cannot get the tablet to charge. I am trying using the USB port, as I cannot be sure the a/c adapter I have is correct. Thanks

If your not getting any indication lights on tablet could be wrong USB adapter transformer. It could also be a bad wire from adapter.
You did not indicate type of tablet or adapter you are using. Worst case you have a bad battery in table and would most likely ha e to be sent in for repair. However if you have a cell phone USB charger for a car try plunging in tablet in and see if it charges. If it does get a new adapter with higher amp than the one your using. But beware the batteries can only be charged to a max amp see web site for you tablet for recomindation.

Plug the tip of the USB charging cable into the power charger port and plug the other end into the USB Power Adapter. Plug the USB Power Adapter into an electrical outlet. You will know that it is completely charged when the orange light on the charge indicator turns green.

How do I reset my Lenovo tablet

You did not say which tablet you have. For Ideatab Android tablet, start with battery fully charged and tablet OFF. Press and hold Volume Up and Power at the same time until menu appears on screen. To navigate the menu, use Volume Down to move through the menu choices, Volume Up to select the current menu choice (like an Enter key) and Power button to return to previous menu. On the "Factory Menu", move down to "Clear eMMC" and select that option. You should see a message that data is being cleared. This may take several minutes to complete. Wait for it. When it completes, the tablet should be reset to the way it came from the factory so you will have to set up again user ids, wifi passwords, download apps, etc.
