Typically, an appliance will not be damaged if it is currently ON and then you unplug its power cord. If you plug it back in the device will simply resume operation as if it were ON.
I found out that when battery is in and then the adapter is plugged, the adapter shuts off (output voltage gradually drops to 0), and the only way to restart it is to unplug it from AC power and plug it in again. Personally I wouldn't risk it. If, as you say, the power cord is short there's a good chance it'll come out during the operation anyway.
Hi rooney10057, Welcome to the Community, The power supply to the battery is automatically cut off once the battery is 100% charged.So even you keep the AC adapter plugged in it does not harm your battery.However to save power its better to unplug and continue to use the system with battery once battery is fully charged.
Typically, an appliance will not be damaged if it is currently ON and then you unplug its power cord. If you plug it back in the device will simply resume operation as if it were ON. I say typically because there are some cases where this may not be the case.
However, you should NOT unplug the battery when fully charged. Every time you unplug the power and use it on battery, you degrade the battery; they are only good for a finite number of charges. In addition, if you use it on battery at your desk, and then need to go portable, you might not have much use time left.
Some of this is true for ALL Lithium-ion batteries. However, you should NOT unplug the battery when fully charged. Every time you unplug the power and use it on battery, you degrade the battery; they are only good for a finite number of charges.
The laptop needs the battery's charge to handle load bursts as the CPU comes out of internal low power modes. You are making it think the power is stabilized by the battery when it's not. The lower-than-expected voltages can result in higher-than-expected internal currents, which can cause serious damage.
Things You Should KnowCut away the damaged part of the cord. Strip the wires and splice them together, making sure the wire colors match or you match the ridge side with the smooth side. Cover the repaired area with a PVC shrink tube and shrink it with a heat gun.
Whether your family walks over them or your pets chew on them, electrical cords wear out over time. Getting replacement cords can be expensive, but fortunately, you can fix most cords on your own for a fraction of the price. No matter how you plan on doing the repair, cut off the damaged portion first.
For a simple, straightforward way to repair a cord, fit it with a new plug. If you can't find a new plug and wish to preserve the cord's length, you could apply metal solder with a soldering iron for a stronger fix. Then, plug in your repaired cord to see that it works as well as a new one again. Cut away the damaged part of the cord.
If the cord is so damaged that you see frayed metal, then you will most likely have to cut it to repair it. Tape is only good for insulating wires, preventing existing superficial damage to prevent it from getting worse. Another option is to fit a PVC shrink tube over the damaged portion. Heat it gently to shrink it and seal off the break.
Here is how to fix a charger cord that won't charge. Heat shrinking will have you saying goodbyes to a broken or fraying charger cable permanently, but you will need to secure a heat gun and some heat shrink tubing. Get some heat-shrink tubing in a size that fits the cable you're trying to repair.
Using a heat gun, some soldering wire, and a cutting tool, you can fix the faulty or broken wires, and restore your laptop's charger to working condition. Check out how to solder stranded wires in the video above.
Look for an update to this article with an OSHA approved cord repair in the near future. Contractors can be brutally tough on their tools, and given enough time, it's not uncommon for a power tool cord to get nicked, damaged or even completely severed.
