Laptop Charging

[Bahco]

I have been given a old Dell laptop which I am trying to charge up but not having much luck.

I have bought a charger with different attachments but I have tried to get it going using the 19 volt attachment pin but I need advice on what I need to do.

I have been to Maplins who said the charger was only putting out 8 volts instead of the reqd 19 vollts.

Any ideas or should I get another charger?

Pics attached.

Hi ColJack.
Thanks for your reply

It is a Dell Inspiron 3000 and is 19 volt.

Good idea to try a computer fair but if there is a quicker option I would like to try it as my little boy wants to play with it NOW!

Hi, It looks like the original dell adapter can output 2.4 amps. What is the universals output? Have you got the polarity correct?

Its all double dutch to me!

Can anyone point me to the correct hardware or computer forum where I can get sorted please.

how about here

Hi, What does it say on the label of the charger you have?
Since you NEED to get the voltage and polarity (positive + and negative -) correct, get one wrong and the laptop can end up dead.

I think the centre is positive + and the outer is negative - but I could be wrong. Does the label underneath the laptop say anything about the charging socket?

model 9935

input AC 100-240V 1.2A 50/60HZ

OUTPUT 50W MAX

Does the label underneath the laptop say anything about the charging socket?

Not that I can see.

Without 100% knowing the correct polarity there a 50/50 chance it will work or damage the laptop.

If Maplins say the charger is not putting out 19v you could see if you could pick up a second hand and Dell charger off ebay.

 

[djrock]

Most universal chargers have a selector switch or dial to manually set the output voltage. Has the charger got one? Is it showing 19V?

We can't go any futher without 100% knowing what the correct polarity is for laptop.

only genuine dell charger will charge a dell laptop, other brands will power it but not charge the battery, i found out the hard way

IF the connection is simply a +/- connection using a std DC power plug then there is nothing special about the chargers and any charger that can supply the correct voltage & current will do the same job.

However I'm sure that this one will do the job, contact the seller & ask.


or this[/ur] or many others on Ebay that are cheaper.

The connector is described as 5.5x2.5 mm
Polarity is centre = +v / outside = 0v.

50w & above is needed, so if it's 90w then thats fine.

P.S. - try it without the battery in as it may be totally flat & causing the PSU to current limit so will not appear to work.

I don't think that will work since I don't know if the battery is used to smooth the supply.
