The battery only reconnects when power is supplied through the external power adapter. The battery does not reconnect when you stop depressing the reset button. Don't worry, the data stored on the hard disc is unaffected. Holding the reset button in for 4 seconds gives sufficient time for the voltage in the memory to decay to zero, so the memory holds no data. However, Acer has provided the battery reset button, which is accessed through the small hole in the back of the computer.ĭepressing the hidden battery reset button disconnects the internal battery and removes power from the computer memory. If that data is somehow causing the appearance of a fault such as the keyboard error described here, the problem will persist for as long as the battery remains connected.īut the computer battery is internal and can only be removed by dismantling the computer, and for most people that is not an option. But on the Acer laptop (and perhaps others) if the external power adapter is removed, and the computer is turned OFF, the internal battery is still connected and supplies sufficient power to enable memory to hold its data. Turning a computer OFF should remove the power supplied to memory and these voltages will quickly decay until a zero state remains. While waiting for a response we decided to try one more idea, which worked, as described below.-Ĭomputer memory holds its state - a voltage representing 1 or a lower voltage representing 0 - while power is connected. So the next step was to contact the supplier and discuss repair or replacement as the laptop was still under an extended warranty. Clearly, it wasn't an operating system / configuration issue. Ask for help The laptop owner contacted Microsoft and their support staff talked her through a number of possible options, none of which worked. Sadly, no change on this troublesome computer. Holding the Function Key and the Numlock key together restores the normal state. Function plus Numlock On some laptops if you have an external keyboard attached, a USB keyboard for example, and remove it, the laptop keyboard doesn't operate as you'd expect. Try to replicate the problem As I said, I have a similar computer, but I couldn't replicate the issue through any setting changes. We tried powering OFF so it shut down completely, leaving it for a while and then starting it. Any problem before sleep mode is there when it wakes up. Power OFF (not sleep) If you close these laptops or press the power button they go to sleep.
