How to charge old Toshiba battery to transfer data to new Acer?

By yowserman ·
I have an old Toshiba 1805-S203 laptop with a broken screen and no power cord. The old cord had a 15V 4A output with center + polarity on adapter.
I'd like to get the data off the old laptop How do I charge the old battery enough to transfer the data? I have a "Tornado" fast transfer cable so I should be able to hook up the two computers via USB ports and transfer the data off the old Toshiba onto the new Acer, if I can charge the Toshiba's battery. The Acer has a 17 v 5A female plugin on it's power cord, but the end is too small. Any suggestions? Frank

Remove the hard drive

TR has reviewed a nifty device called Coolmax Adapter:

Plug the removed hard drive into the adapter, and transfer the data to the new machine.

Radio Shack makes and sells a universal adapter that comes with switchable polarity and a selection of plug connectors. You could also charge the battery externally too with this unit and some alligator clips. With a broken display, you could connect an external monitor to see what's going on. Good luck

Don't think it will work, see belolw

by fctrigg In reply to Try this

I bought a universal adaptor with 8 different tips to charge or run a variety of devices, like Ipods or other music players, games, most everything. It only goes up to 12 volts and you can hook the ends up with either positive or negative polarity. I was told by two different people that I couldn't charge a battery if the charger ran less volts than the battery. is that true and if I charge it with a 12 V charge will it charge the 15 v battery enouth to transfer the data?

charger

by eltonpiko In reply to Don't think it will work, ...

the answer is no a 12v adapter will never charge a 15v battery ,well it will but its gona take for ever and the battery will discarge very fast too cause the power is noot sufficant to boost the battery.

what you can do is take the battery pack out of the laptop.get an old pc power supply locate your positive and negative on you battery.use the wire on the power supply that goes to the hd or cd drive that has 4 wire (red,black,black,yellow).

cut out a black & yellow wire.use the yellow one for positive and black for negative connect it to your battery the correct way.it will surely charge the battery in few hour to give you enough charge to do your transfer.

hope this help

Thanks, and another question concerning same sub

by yowserman In reply to charger

Could you hook one 12 volt motorcycle battery with one six volt Lantern battery in series(?) to make a 18 volt battery and charge the 15 volt laptop battery?
We used to start old cars that hadn't been started in a long time by hooking two six volt batteries (back in the olden days when cars ran on six volts)to jump start them with a 12 volt charge which really turned the engine over fast. You could do it as long as you made sure not to overheat the starter, and if you didn't try to run the lights or radio it didn't seem to hurt anything. I'm thinking you might charge the old laptop enough without too much damage and be able to run the disk drive long enough to pull the data off the drive. Make sense?

I hope you're pulling our leg....

Directly connecting the laptop battery to the motorcycle/lantern battery would be a 'youtube' moment (have the video camera handy).

The motocycle battery can supply around 300 amps. The internal resistance of the lantern battery would cause it to swell and probably explode if any sort of circuit were made with it in series.

At best, the internal charging/current limiting circuitry inside the laptop battery pack would instantly cook/smoke/vaporize.

At the worst, the lithium ion cells will explode like six M80 type firecrackers.

The microelectronics inside the battery pack is there to prevent fire/explosion and are VERY delicate.

I was smart enough to ask though. Knowing you're not too bright is sometimes bright enough. Thanks

Sorry, I didn't mean to sound mean....

But I would hate to see somebody get hurt or **** up any perfectly good electronic stuff, unless that's what you're trying to do.

So far the best approach I've heard for your laptop problem is to get an external USB drive case. One of these will hold just about any stndard 2.5" laptop hard drive. By removing a couple of screws, you can easily get that hard drive out.

Here are some as cheap as $8

bad idea

by eltonpiko In reply to Thanks, and another quest ...

no man you should realy be a daredevil to try out this stunt.before you do the last connection i sugesed you stand far back as posible as you watch you laptop battery fry with teirs.so pleas dont try it.
i sugess you get a variac dc power supply could solve all your charging problem but dont over voltage it or a better to get an extrenal usb hd case that you can put the hd inside like idearobo_dev said.

Solar Battery Charger --- Give timely additional juice to Battery

by b2cwholesale In reply to How to charge old Toshib ...

I can said portable solar charger (built in large capacity li-ion battery) is a better emergency solution for most consumer electronics.

Try this. http://simenibiz.com/green-sun-power-energy-charger-wholesale/900-12000mah-solar-charger-for-laptop-5-9-12-16-19v.html


Simple Guidelines---How to prolong lithium-based batteries?

* Avoid frequent full discharges because this puts additional strain on the battery. Several partial discharges with frequent recharges are better for lithium-ion than one deep one. Recharging a partially charged lithium-ion does not cause harm because there is no memory. (In this respect, lithium-ion differs from nickel-based batteries.) Short battery life in a laptop is mainly cause by heat rather than charge / discharge patterns.

* Batteries with fuel gauge (laptops) should be calibrated by applying a deliberate full discharge once every 30 charges. Running the pack down in the equipment does this. If ignored, the fuel gauge will become increasingly less accurate and in some cases cut off the device prematurely.

* Keep the lithium-ion battery cool. Avoid a hot car. For prolonged storage, keep the battery at a 40% charge level.

* Consider removing the battery from a laptop when running on fixed power. (Some laptop manufacturers are concerned about dust and moisture accumulating inside the battery casing.)

* Avoid purchasing spare lithium-ion batteries for later use. Observe manufacturing dates. Do not buy old stock, even if sold at clearance prices.

* If you have a spare lithium-ion battery, use one to the fullest and keep the other cool by placing it in the refrigerator. Do not freeze the battery. For best results, store the battery at 40% state-of-charge.
