ok so i just got back from best buy.. and the guy told me that leaving your computer plugged into your charger

Question

will hurt the computer... is that true?? (is it also true for ipods and cell phones)

Answer 1

True, almost--it won't hurt the system as much as it will hurt the rechargeable battery.

If you let an electronic system run constantly then it should have no problems, as long as it can handle the heat (home train transformers aren't able to do it). The newer notebooks use less power so they generate less heat, but the older ones may need more help. I have seen notebook computers that have two fans and sit at an angle. This lets the heat, from the bottom of the notebook, be pulled out by the fans and then run underneath the cooler to go to the outside.

Rechargeable batteries develop a memory. If you charge the device up to maximum and then keep charging it up to that point, then the battery will hold a little less charge each time. The proper way to maintain a rechargeable battery is to let it discharge over time or through a heavy resistor. Take the battery down to the lowest level you can before you recharge it again. This helps the battery to NOT develop that memory since its power level goes across the board. A voltmeter typically uses a large resistor so that is how I discharge my portable batteries. For the notebook I would periodically leave the notebook on and let the charge run down until it is depleted. This doesn't take very long, typically overnight. Another trick that I use is that I have two batteries. I can charge one up and use it as much as I want then the power starts to get low I switch to the second battery and let the first one sit for a while so it will drain on its own.

Some brands of notebooks can be directly off the charger, without having a battery inside. All notebooks us a charger to convert the AC power down to a lower voltage DC power. It uses a transformer to do this and as part of the process it generates excessive heat. In many notebooks the charger is kept near the wall or in the middle of the cord so its heat won't disturb the computer. The transformers for electric trains are the worst at this and if you leave on plugged in over night then you can burn it out.

Answer 2

as far as your computer goes i am not sure because some devices will automatically stop the eletric flow once full. some will not those that do not can over charge and kill your battery so i think it depends on your device and the technology of it. usually chargers will overcharge a phone and then decrease the longevity of your battery life...i honestl charge everything for about 4 hours and after that i leave them off...cell phones, pda's and my laptop. just to be on the safe side

Answer 3

if your going to leave the laptop on the charger ...run the battery down to 40 percent ..take it out of the laptop and store it..

ipods refer to apple.com

cell phone- the battery does mess up if you keep it on the charger for a long time after fully charged.

Answer 4

the box on the cord for a laptop is a convert that will eventually burn out. leaving it plugged in will make that one part burn out faster and need to be replaced, but it wont hurt the actual computer

Answer 5

yes, I left my laptop battery on the charger for a day or two and the battery doesn't hold a charge anymore, it always has to be plugged in :-(

Answer 6

I know with my laptop that like every 30 days you're supposed to let the battery run out, but I think as long as that is done, then it's fine.

Answer 7

certain, that is why you ought to apply a router with a firewall to dam undesirable incoming site visitors from the web. you do not have self belief what number of human beings using a familiar modem I actually have had to communicate into using a router (which has a outfitted-in modem) with a firewall. i understand that devoid of firewall you ought to in all likelihood have viruses interior of seconds. devoid of the threat-free practices of a firewall it truly is a threat that someone can see the contents of your not ordinary disk from the web.

Answer 8

Oh my God, Someone from best buy actually gave you right advice!
