Question about Gateway M685-E Notebook

Open Question

There is apparently a battery detection circuit on the M685E motherboard, installed because of the instability of Li Ion technology. I want to use different chemistry so need to fool the detection circuit on the MB. How can I do this?

I need the XLR pinout for my Air Hawk portable wheelchair. The charger fell out of the wheelchair pocket on a flight, I need to charge the 24 V battery Li-Ion so I can make it back home with power.


is this ref any use ?

be careful over what charger you use as Li-ion batteries must not be overcharged. most have a sensor that detects the voltage and stops charging when the battery is fully charged. This circuitry is inside the charger, not the pin.

Tips for improving lithium-ion notebook battery life


Replacement batteries for laptops can be quite expensive, so here are a few ideas to get the most out of your battery in terms of charge and overall life.<br /><br /><span style="font-weight: bold;">Background information</span><br /><br />Most modern laptop batteries are of the lithium-ion ("li-ion2) variety. You can expect them to last two to four years if properly cared for. They will degrade over time, whether or not they are in use. They last best at a temperature of 15&deg;C/59&deg;F, although it is unlikely to be practical to use them at this temperature.<br /><br />This is a chemical technology, which is under continual development, so it is entirely conceivable that a new li-ion battery for an old laptop will last much better than the original battery did. This and other factors make it fairly hard to predict how long your laptop will last on one charge. All you can do is to try and get the best out of your particular battery.<br /><br /><span style="font-style: italic;"><span style="font-weight: bold;">Did you know?</span> Early li-ion notebook batteries were known to explode! Modern batteries have protection circuits built in which prevent the lithium ion converting into unstable lithium metal.</span><br /><br /><span style="font-weight: bold;">Power consumption tips</span><br /><br /> <ul> <li>Reduce the brightness of your screen when running on batteries.</li> <li>Use a blank screensaver, and set it to operate after a relatively short period of inactivity. Better still, switch off or hibernate your laptop if you won't be using it for more than 5 minutes or so.</li> <li>Set your power options (e.g. in Windows control panel) to minimize power consumption. This includes having hard drives power down as much as possible.</li> <li>Switch off wireless networking, if you're not using it.</li> <li>Unplug all PCMCIA cards (or similar) and USB devices that you're not using. Ditto optical drives (CDROM etc).</li> <li>Certain specialist notebook graphics cards can be set to run "underclocked" at less than their full potential. This saves energy. Do this with caution though, because it can cause conflicts with certain graphics software.</li> <li>Close all the programs you're not using. This includes all the programs that run in the background, unused services in Windows, etc. Which services to stop is beyond the scope of this blog entry.</li> <li>Certain sound chips have a power saving mode that can be activated via the control panel.</li></ul><br /><span>Caution when hot!</span><span style="font-style: italic;"> It is inadvisable to use a li-ion battery when particularly hot. Heat can generally be a problem with laptops, so make sure that all the vents are clear, that the laptop is not sitting on a highly insulating material (e.g. sat on a duvet when used in bed!) and that all fans are operating as they should.</span><br /><br /><span style="font-weight: bold;">Battery life tips</span><br /><br /> <ul> <li>Do not keep the laptop plugged in whilst the battery is installed; this keeps the battery on a permanent charge/ discharge cycle which will cause it to age rapidly. Instead remove the battery if you're running on AC power.</li> <li>If you're going to store the battery or leave it unused for any length of time, discharge it first to about 40% capacity - never fully discharge a li-ion battery. Aim to store it at around 15&deg;C/59&deg;F (see above).</li> <li>You do not need to discharge or charge a li-ion battery fully - they do not suffer from the "memory effect" experienced with nickel cadmium or nickel metal hydride rechargeables. So only discharge partially - avoid going below 20% capacity if you can.</li> <li>When the battery is full or at over 95% charge, stop charging it!</li> <li>Don't bother buying old stock of batteries no matter how cheap, since they will have degraded for the above reasons.</li></ul><br /><span style="font-style: italic;"><span style="font-weight: bold;">Remember to recycle.</span> Li-ion batteries should be recycled wherever possible. Your council may have suitable local facilities.</span>

Need replacement Lead acid battery for Curry's Electrodrive


Just in case you dont know, you can save $ by getting 2 12v 10 amp-hour batteries and installing them in that case. That's whats in there. They have a Li-ion version, but it's only 6.4 amp-hours and around $350.

Can you use 18v lithium battery in old 18v drill


Yes you can. On tools, 18 volts is 18 volts. Tools don't 'know' how the power is being created, either by Ni-Cad or Li-Ion means. Chargers are totally different. Most Li-Ion chargers can charge older Ni-Cad and some Ni-MH batteries but older Ni-Cad chargers will charge Li-Ion battery untill they overheat and sometimes start on fire because older chargers can't detect when the Li-Ion batteries are full.

I HAVE INTEL DG31GL MOTBOARD I HAVE ONE PROBLEAM IN MOTBOARD IS NO DIPLAY ONE SINGNAL LIGHT IS GLOW


Hell Krishna,

The display problem is common in all the Intel DG31GL motherboard. Please switch off the computer first. Then remove the Li-ion cell/ battery of the mother board. Replace it with new Li-ion cell/ battery.Also remove the ram of the motherboard. Insert the cell/battery in the motherboard and switch on the computer without installing the ram. After 2 to 3 beeps switch off the computer and install the ram and then switch on the computer. The display will come again.

Sat nav tontom one whont charge or come on


Your battery has probably gone and since it is a Li-ion battery, it has sent a signal to the TomTom not to turn on. This is a battery protection circuit in the Li-ion battery. You probably have to replace the battery

Logitech MX1000 Laser Cordless Mouse, I replaced the li-ion battery with a NiMh AAA battery pack, soldered in the board that was on the old battery and used it for a week before the battery pack needed...


Li-Ion battery and NiMh battery have completely different charging requirements! Li-Ion battery has much stricter charging requirement and the regulator is normally design to trickle charge at 0.1 Current rating @ 4.2V and then completely shut down.
WARNING: if you use a Ni-Mh charger on a Li-Ion battery, then it will erupt and even explode and catch fire!
Bottom line is that the rescued Li-ion regulator is not designed for your Ni-Mh pack and you will never get a full charge with it and you will need a completely different regulator board: you are better off putting in a suitably sized Li-Ion battery with inbuilt regulator but with higher current rating if possible.
Hope it helps! Let me know how you go.

Battery charger just flashes to say the battery has to cool down but will not start charging.tried another charger same thing happens but does not show that the batteries are faulty!


Unfortunately, Makita’s li-ion battery packs have a design flaw. After having the same problem with my two batteries, I took it apart and saw the problem immediately. You see each battery pack has ten li-ion battery cells and a circuit board with a memory chip witch holds the charging history of the battery pack. But that memory chip constantly draws power from 2 of the 10 batteries. The current it draws is very small but if you consider it over 6 month or more, the power drain becomes very significant. You end up with a battery pack with 8 still fully charged battery cells and 2 drained battery cells. When you put this battery pack in the charger, it detects weak battery cells, assumes they are defective and refuses to charge. To avoid this problem you should charge your battery pack often, even if you haven't used it, every two months should be ok.
I suspect that Makita doesn’t make these battery packs, they make power tools, good ones too. But Makita should definitely have a few words with their supplier before they become a liability!
