I have a gateway laptop and the battery will not charge. There are
several contacts on it and its rated at 11.1 volts. Any ideas how to
manually charge it I would assume that its a 6 cell battery because
there are 7 contacts one is a bigger size then the others I would
assume that is the neg contact. Any idea on each of those contacts
are there suppose to be 11.1 volts or does the laptop take each cell
and wire them in series to get 11.1
Thanks
Rick

What good will that do, the battery is dead, not function, knackered,
TFU, gone, passed away...

What kind of insane logic dictates that?

Wow, please be sure your insurance is fully paid up before going any
further!

Go to eBay and buy a new battery.

What is the model number of the laptop?
What is the model number written on the cell?

What's the chemistry and mAh rating written on the battery?
- Lithium ion (Li-ion) or Nickel Metal Hydride? (NiMH)

With all that, the OEM replacement can be found - or if NiMH equivalent
cells, found to replace those inside. eBay.

The laptop supplies 11.1 volts carefully controled by the internal
charging circuit. It is a smart battery that can't be charged outside
the computer because it has a microprocessor controlled charging circuit
built in that talks to your computer in order to keep the battery from
either overheating or over charging.

It will not allow you to charge it without the control system in the
computer. It's likely that your battery has bad cells or blown protection
fuses internally that are preventing the circuit from allowing it to
charge.

It is very difficult to disassemble the battery case without damaging
anything inside and possibly causing a fire. These batteries will combust
if shorted.

I would not have asked the question if the battery is dead. I have
something wrong with my laptop. I have a friend with the same battery
and have had them charge the battery for me by placing it in the
laptop over night. Im not paying anything to fix the laptop it would
probably be more than its worth. About the contacts or cells on the
battery you seem to be very sarcastic. You tell me what the contacts
are for. I am under the assumption that when buying a laptop battery
you can buy a 6 cell or 8 cell battery. So again please explain to me
what the 7 contacts are for on the battery
Thanks

Thanks Gnack
PeterD has it wrong the battery is not dead I can charge it on a
friends laptop (same model) so Im assuming that something is wrong
with my laptop it will only work on AC or the battery if I have it
charged. It would probably be to expensive to have the laptop
repaired so I was just wondering if I could charge is externally.
Thanks

Likely the laptop's charging circuit is in trouble but there is one thing
I can suggest that may help you. If you look at the contact set in the
computer and see any discoloration on the gold pins try cleaning them
gently and preferably with a cotton swab soaked on 95% alcohol. That may
get the battery and charger talking again.

Nothing beats leaving out significant information in your original
post, is there?

are for.

Some of the contacts are used to communicate with the battery. Others
are used for power.

Is the original adaptor being used, or is the power adaptor you are
using actually faulty? Try the one belonging to your friend on your laptop.

I don't know your laptop model, but some laptop manufacturers (namely
Dell) are selling them with specific power supplies that ID themselves
to the the machine before allowing charging. Sometimes the ID pin on the
PSU connector or the equivalent on the laptop fails to connect / breaks.
 
I have a gateway laptop and the battery will not charge.  

You can get standalone chargers for some laptop batteries, but your
cheapest solution is probably to buy a "spares or repairs" dead laptop
which takes the same battery and hope its charger circuit still works
even if the laptop won't boot. Machines with faults like smashed
screen or lost password go quite cheaply on eBay.

Sometimes there is no ID pin, they signal the charger serial number,
capacity etc. over the power rail.
