Customer ServiceFinal Thoughts. In conclusion, a laptop can run without a battery if plugged into a power source. It can be helpful for those who have lost or damaged batteries and need to use a laptop immediately. However, it is essential to note that running a laptop without a battery may lead to decreased performance and potential damage to the device in the long term.
Customer ServiceThis time i wanted to try and power the phone directly through a DC power supply connected to the battery pins, so that the battery would not be an issue. I reached this solution online and found out it was possible, but i need a small step down voltage regulator between the phone and the power source, as seen here:
Customer ServiceMy solution: I have a 12V wall power supply that goes up to next the tablet, and then have an adjustable DC-DC converter that goes from the 12V to the battery connector inside the tablet. For soldered batteries, you have to solder the connector. For connector batteries, you can use the connector. You want to adjust beforehand the DC-DC
Customer ServiceDirect Power Source: Tablets can connect directly to a wall outlet using an AC adapter. The device receives electricity through the charging port, enabling it to function
Customer ServiceTo use a suitable circuit that will simulate the battery presence so that the tablet can be run when attached to the charger (we assume that with the original battery fully discharged the tablet runs ok). The circuit might use a smaller battery and or a supercapacitor or some other magic gizmo to do what follows (note: only point I is strictly
Customer ServiceUnfortunately, some laptops can become excessively dependent on a power source when used without a battery. This can be a major drawback for users who rely on their laptops for portability and flexibility. When a laptop is plugged into a power source without a battery, it relies solely on the continuous supply of electricity. This means that if

Customer ServiceWhat will happen if a LED is directly connected to a power supply? When the LED is directly connected to power (AC – Altering Current), it burns. The optimal voltage and current required for an LED in 2–3 Volts and 10–30mA (12–20mA is the most common range)respectively. The output of an AC is much higher than the operational power of an
Customer ServiceY soldered some capacitors and a diode to a female USB port. And made a custom male to male cable to connect to a charger brick. The capacitors are needed because the signal from the brick is not so stable. An other tablet (Samsung galaxy tab 2 10") can also be powered by this method. A cellphone can easily be powered by a 5v 1A

Customer ServiceThe ability to use a tablet while charging without a battery depends on the device’s power supply architecture and circuit design, with varying support across different android tablet models. When using a tablet without a connected battery, the power supply becomes the sole source of operational integrity.
For tablets primarily used in fixed locations, an alternative approach could be to use a power adapter that bypasses the need for a battery altogether. In situations where the tablet’s mobility is not a primary concern, this strategy can offer convenience while reducing costs.
Alternatives to running a tablet without a battery include options such as replacing the battery, utilizing a power bank, or considering a new tablet replacement to address power management needs. When dealing with a tablet’s power needs, replacing the battery can be a practical solution.
When dealing with a tablet’s power needs, replacing the battery can be a practical solution. It allows the tablet to retain its portability and can often be a cost-effective choice if the tablet is still in good condition. On the other hand, using a power bank offers flexibility, enabling the tablet to be charged on the go.
Without a battery, the tablet may be more susceptible to damage from power fluctuations and voltage irregularities, potentially leading to malfunctions and hardware issues. The absence of a battery can significantly impact the portability of the tablet.
When modern android tablets are used while plugged in without a battery, the device might encounter power fluctuations, affecting its ability to maintain a consistent power supply. This is primarily due to the circuit design, which is optimized for powering the device and managing power flow when a battery is present.
