Question about Apple MacBook Pro Laptop Computer with Intel Duo Core 15.4 Inch PC Notebook

1 Answer

My Macbook Pro's charger cord is a little coming off the tip and exposing the wires inside. Today I had my battery fully charged but after 5 minutes of use it turned off. I shut down the computer and took out the battery. Later I put the battery back in and charged it, turned it on and it resumed to the same place. Everything is working fine, but can someone tell me why that happened, should I switch the charger?

Cable short. Replace the charger or you risk an exploding battery.

Goes through charging process Red light blinks then green light blinks like it is charging then after a few seconds solid green as if fully charged but it is still dead


I had the same problem. Your battery sounds like it got drained too much. The voltage on the battery is too low for the charger to charge. I looked on YouTube (how to charge battery that won't charge). I actually tried this today. I had a battery attached to one of those flashlights from a combo pack and the battery was drained down to 0.64v. The video I watched said take a higher voltage batter and boost it. Like a 20v to boost your 18v. Attach wires from one to the other. + to + and - to - I didn't have any. So what I did was stick 9v batteries together + to - in series I had 5 laying around. I taped a wire to the exposed terminals on the two end batteries and tapped the wire on the battery, which only brought it up to about 2.3volts. Then I just held the two wire on the battery for about a minute. It went up to about 6.3 volts I plugged it in the charger and it finally started charging. I don't know how well it will keep a charge. The batter is 10 or 12 years old. Hope this helps. And check YouTube. There is a lot of videos there.

Why isn't my laptop charging?


Remove the battery and let the computer sit for about 5 minutes. Replace battery and plug in AC cord. Try to start computer. If the computer will not turn on, then chances are that your battery is fully uncharged. Check to ensure that the AC charger is working properly (voltage test with multimeter). If the AC charger is not working, you need to replace it. The laptop should work without a charged battery if the AC adapter is functioning properly.

My macbook pro won't charge, why is the charger not working


make sure that the connection between the charger and macbook is clean.

If the charger lights up green and doesn't change to orange, then it may not be connecting. If it stays green, the battery might be dead or improperly inserted. It may need a different sized cord -- check for proper wattage.

Asus UL50VT always shows charging


Either your battery or the power cord has an issue. Does the battery ever fully charge and make the charging light disappear or turn green? If not the battery could be bad.

Try running the computer off the battery by removing the power cord. if the battery starts losing charging strength real quick then your battery is bad. I've see bad batteries that say they are 100% charged but as soon as you remove the power cord it gets down to 5% i a matter of minutes.

Try running the computer on just the power cord. If it stays on and lets you operate without any problem then the power cord is good. A good power cord will not charge a bad battery.

If the laptop does not let you stay on long with the power cord, then either the power cord is bad or the DC Power Jack where the power cord plugs into the laptop is bad. If either of them is bad they will not charge a good battery.

Check your DC Power Jack which is where the power cord plugs into the computer is bad. Take an ink pen and push the tip inside the jack and see if the little pin wiggles, if so the jack is bad. You'll have to take the laptop apart to fix it. Most times it is soldered onto the motherboard, so you will have to desolder the old and solder a new one.

Iphone 3g proper charging


Once you purchase the iphone,dont use it yet.Instead of using it right away,kindly charge your IPhone with the wall charger for 3 hrs.Please dont use the Iphone while charging.Kindly check always if the battery is full.Once its fully charged then that's the time that you can use the iPhone. Once fully charged, let the iPhone's battery fully drain.Please keep the iPhone off for 2 hours.Fully charge your iPhone and allow the battery to rest in the fully charged state for two hours. (You may use your iPhone during this time as long as the iPhone is plugged in).Repeat the third and fourth step a maximum of three times if you feel your battery indicator is inaccurate.

Here are some tips for your everyday charging for your IPhone:
#1 - Charge your iPhone throughout the day when available. Charge EVERY night, regardless of charge level. This will keep your battery active, which is healthy for the iPhone's battery.
#2 - Use a wall charger or car charger w/ rated output 5V 1A. Computer chargers might not charge when the computer is in standby mode.
#3 - You cannot overcharge your iPhone. You don't need to disconnect the iPhone from the charger after it's done charging. Once fully charged, the iPhone will run strictly off of AC power and will not damage the battery.
#4 - Every two months, make sure you fully charge and fully drain the battery, in one cycle. This calibrates your battery indicator. If you fail to do this, your indicator will become inaccurate. Calibrating your battery does not improve battery life.
#5 - If you ever need to store your iPhone for any reason, make sure your battery is stored @ roughly 50% and in a cool environment.
#6 - Always charge your iPhone out of its case (assuming you can easily remove the case). Charging your iPhone inside your case will make the iPhone hotter, which is bad for the battery.
#7 - Charge your iPhone in a cool location. Charging your iPhone in a cool environment has a tremendous impact on your battery's lifespan. The colder the location you use to charge, the more charging cycles you can complete without your battery deteriorating. Avoid charging in direct sunlight.
#8 - Use properly rated chargers. Using chargers that are not properly rated will have a huge impact on your battery's lifespan. Make sure your car charger has the same rating as the official Apple charger.
The official Apple wall charger is rated as follows:
Input: 100 240V ~ 50/60 Hz 1.0A
Output: 5V 1A
Thanks!

Panasonic vx37


My old Panasonic Palmcorder IQ shows a red light in both switch positions-camera and VCR. Maybe yours has red for camera and green for VCR so you could tell them apart. I found that the Panasonic battery that came with the camera was the cheapest kind with the least charging time. I bought other batteries, they were good for a while, but now, many years later, they won' t hold a charge. Since I am only recording inside of my house, I have resorted to using the AC wall socket for power. I have to take the battery out of the camera. I found a power plug-in hole (like ones on cell phones) in the battery compartment. I also found one of these holes on my battery charger. My camera came with a double ended power plug. I plug one end into my camera and the other end into the battery charger. I plug the charger power cord into the wall outlet, and I have power to my older camera. Maybe you can find this double ended power cord at a store or on line.

Did you know that there are 2 kinds of batteries? Some have memories and others do not rely on a memory. The ones with memories have to be fully discharged or they will only charge a little, and keep charging less and less each time they are charged. The ones without the memory can be charged fully without being discharged fully. Check into battery information on line to get more information. Maybe you can get the non-memory kind.

Ds lite charging lite comes on but when i press power button nothing happens


Are you leaving the DS charge until the light comes off? Remember that there are two likes too, one for charging and one for power. If you're just charging for some random period of time (lets say... One hour) then your Battery isn't going to be fully charged. The best way to ensure that your DS Lite is charged is to leave it charge until the charge light turns off. You can play your DS Lite while you are charging (I do it all the time), but it just means that you're just running off of the outlet.

A good test is to charge it fully (until the charge light comes off), unplug the charger cord (Make sure it's secured tightly to your DS while charging), then play for a little bit, your light should be a normal color (green).

If you cannot even play by using the outlet, then you need to
find a charger cord that actually works (You may need to send in the charger for replacement). If the same thing happens with 2 different batteries (assuming that you have two official Nintendo batteries).

TIP: Also run your fingers across the Charger cord. You're going to get a slight friction burn from the rubber, but you're going to get all of the kinks out of the wire in the cord. My charger cord had a similar problem (did not charge all the way, only charged until I moved the DS) but when I ran my fingers across it (pinching) it worked again.

Also check the pins in both charger cords, charging will not work if one pin is missing, nor if any are bent.

Fully charged Lithium batteries dies out too quick and the USB cable does not work? Please help. thank you.


If the lithium batteries are of the AA shape then put them in a small torch and leave the torch on to fully run them down. If they are of an odd shape endeavor to do this with bulb wire and tape. Then try recharging them. If this fails- simply get a new set of batteries at first. Then come back

Phone doesn't hold a charge


MzRendevous, It sounds like you do have a battery issue. Batteries for cell phone don't tend to last long, but if you do purchase a battery, try this to get longer life from the battery. 1. Charge the battery without using the phone until the battery is fully charged. 2. Once fully charged, use the phone like you normally do until the phone shuts itself down because there is no power. 3. Charge the battery again without using the phone until fully charged. 4. Then you can use the phone and charge it anytime you want. You can repeat these steps as much as you want, the more you do it, the more life you'll get from the battery. -- As far as the charger, if you have to adjust it to get it to charge, it could be the cord or the prong on the inside. I'd goto a store and test another charger, if it's available. You can probably get cheap batteries/charges on EBay or anywhere on the internet. Let me know if I was helpful for your questions. John
