Using a Dell charger for my HP TM2

Hi,

I have a Dell E4300 (For Work) and a personal HP TM2 for my college. I have to carry both laptops since I go to college after work and use my TM2. Anyway, I realised that the power cords/connection tips are EXACTLY identical. and then i looked at the voltage/watts etc and its almost identical in both except for the Amp in one. So, how bad would it be to use the dell charger ( I have the slim travel charger from dell, so its alot easier to carry around as well)

Here are the specs:

HP Charger:
Input: AC100-240V (worldwide use)
Output: DC 18.5V 3.5A
Power: 65W 65 WATT

Dell Charger:
Input: AC100-240V (worldwide use)
Output: DC 19.5V 3.34A
Power: 65W 65 WATT

 

When you use the Dell Charger to power the TM2, you are effectively 'overvolting' the power/charging circuits of the HP by 5% which should be more than the leeway built into the HP charging system.

However, even if it is within the leeway; it is still overvolting them and the circuit will eventually die sooner (compared to the normal/recommended charger).

So, your call: convenience (use just 1 charger) or, longetivity (for the HP)...

Are you a betting man?

I'm not.

 

Well, in this case, I think I will use the HP charger for my Dell .its not too big anyway so Im fine with it , just as long as its one charger, and since the voltage is lower, It shouldnt do much harm to the dell battery. (This just occured to me )

 

Actually, using the HP charger (essentially undervolting the Dell) is worse than the overvolting.

Why? Because the Dell will basically be starved for power (it needs it's 19.5V) and the struggle that the power supply will be going through may well be enough to make it give up the ghost - while hopefully not frying your Dell in the process.

Again: if you are a betting man and more importantly can replace either of these notebooks on a whim, then go ahead and try to be a few ounces lighter.

I can try to give you basic information: you have to have the wisdom to use it wisely.

Good luck.

 

Thanks for the quick reply and the very useful info !

Well, the way i figured it out is that......going lighter is absolutely important for me so I decided to go ahead and do this, but the question is which one will suffer and the way I see it, the Dell laptop is from work and they can afford a new battery more than i do

So...........I will risk it with the dell , I will let you know if the battery dies out on my in no time


Thanks again for all the info.

 

It's not the battery I'm worried about.

How 'safe' is your job position if you kill the company's notebook?

Good luck.

 

lol

I would say pretty safe, im the I.T Manager

Anyway, the dell is under warranty so if anything happens to it (besides the battery) I could always get it replaced for no charge

 

If they replace it, it's only going to be out of goodwill, not because it's covered damage. You're required to send the charger with the laptop when it goes in for service. It takes about 10 second with a multimeter to realize the charger is putting out good amps and voltage, and maybe 5 minutes to figure out the laptop's been undervolted.

 

You guys tried,you can lead a hoarse to water,but you cant makem drink....
