Can i directly hook up the neg and positive wire to my cell battery and charge it


popped off the battery cover and noyiced the + & - signs on the battery almost lined up perfectly with the contacts on the sides
so fugurring that since the charge from USB port, figured the 5V 0.5A power source would work for the same side connectors. cut up the seperate USB cable layng around and stripped down the red (+5V) and black (Gnd ) wires.
from there bunched them up and stuffed the red one into the left contact and taped it down with electrical tape and then did the same with the black wire in the right contact. make sure to use as much wire as you can without touching the 2 wires/contacts and taped them down seperately and nice and firm.
plugged in to the computer for about 25 min and it was completely drained and nearly 1/4 full power.wait for to get it fully charged and then just bring this cable and electrical tape with you and you can charge your cell with your lap top

Insert SIM Card Problem Fix


The "Insert SIM Card" problem can be irritating when it keeps on popping up even when a SIM card is actually been inserted into the phone's SIM card holder. It can sometimes be remedied by cleaning both the SIM card and the holder terminals with a cotton swab immersed in alcohol; most preferably 70% alcohol solution. Sometimes the holder is not tightly holding the SIM card causing the problem. This can be solved by padding up the back of the SIM card with a small sheet paper or any appropriate material enough for the holder to hold the SIM card tightly. Another way to fix the problem is by bending in the mid-section of the SIM holder cover.

Nokia 1110, 1110i, 1200, 1028, 1209 and all other member of the family of Nokia phones with USB ports similar to the ones mentioned earlier have the tendencies to experience the "Insert SIM Card" problem not due to a dirty terminals nor a loose holder but due to dirty, soiled, or oxidized USB port terminals. The fix is just as simple as cleaning the USB port terminals but make sure to remove the phone battery prior to the cleaning. Use a paper clip, a safety pin, or a needle with bended tip to scrape off the dirt between the port terminals and dip it in alcohol to wash it out.

The cleaning can be done without the necessity of disassembling the phone but if proper tools are available, disassemble the phone to clean the inside of the system connector, the one where the USB port, the charging socket, and the headset socket are located.

People may wonder how a dirty USB port can lead to the "Insert SIM Card" issue and guess what; it is not even included in the Nokia Service Manual. The fix was discovered accidentally and proven many times that a dirty USB port is indeed the source of the problem.

This type of camera usually downloads better with a Firewire (DV) connection. Some mini-DV cameras only use the USB connection for stills (if they have one) and can only download video by Firewire. This is because you have to play the tape into the computer, not just copy a file.

Most PCs have a USB port, but no Firewire port. Macs often have a Firewire port but may not have USB. With desktop Windows PCs, you can fit an add-on Firewire interface card. This comes with a driver for the card. If your laptop doesn't have a Firewire socket, then you are probably stuck.

My usb port my mouse is plugged into wont hold, it's loose can this be replaced?


Hi:
This is not an easily replaceable part, and often these usb ports are directly soldered onto the motherboard. A good solution might be to buy a USB PCMCIA card that plugs into your PCMCIA card slot. This will give you extra USB ports, and won't require surgery on your laptop!

I had the same problem with mouse, it happens when devices connected to two USB ports that are close to each other, so I connected mouse in the back of computer USB and printer in the front USB (or reverse), or further away from each other.

My lg vu will not charge


There are 2 possible problems you are having. You charger is going bad as evidenced by th cable going bad. Take it to a carriers store and try a different charger.

The other issue may be the charging port is going bad. Having to tape the charger may be an indication of that.

Try a different charger first but if that is not the problem check out the following link for ways to fix the charge port on your LG VU
