I have an advent LE1D 7000 which gets so hot that the tip that goes into the back from the powerpack gets red hot.. The original power pack I got with the laptop broke and so I got a generic multi adaptor which after about 2 months the tip for my laptop broke. the shop replaced the whole unit but my new tip is still red hot also the web and walk stick I use for the internet gets red hot as well. I have hd to stop using the laptop with the power on ac and only have 3o minutes left on my battery so get hardly any time on the internet at any one time. the original powerpack was a 65 watt but the one I have now is 120 w. with the old power pack the box on it got very very hot and the one I have now does not. The laptop is really really hot at the bottom I don't know if the fans work and don't know how to tell!! has anyone any advice? thank you

Just one thought. When you bought the generic powerpack, did you check that its output is correct in terms of the voltage and amps that it delivers? i.e. in line with the old one.

thank you for your reply - I will find my laptop book and do the checks you suggest.

hello grasshopper

on my old original adaptor it says

input 100-240v - 50-60Hz 1.7A
output 19v (then a line with three little lines underneath)3.42A
wattage 65 it says in the manual for my laptop
no other figures

on the generic one it says (amongst other figures but I think the ones below are what you need to know)

rated input voltage (47-63HZ)
AC 120v or AC 230v
input rated current 1.8A
output current 6.OA (600 mA)
DC 15/16/17/18/19/20V
5.OA - DC 22/24V (5000 ma)
from the voltage choice on the generic I have the output set to 19V

the polarity matches

there is a light on the new adaptor which will only light if overloaded or short circuit - that never lights up

it also says on the generic ones box the voltage has to be the same but the current rating can be the same or higher on the powre supply

I don't really understand any of this but hope this clarifies the situation!

many thanks

Those figures look fine so provided the generic powerpack is performing correctly, that can't be the problem.

Although the fact that the tip gets hot and the web & walk, which is drawing power from the USB socket, also gets very hot, does make it feel like a current issue. But it could be the circuitary in the laptop.

You really need someone who has got the equipment to test it.

Or it could be that the laptop is just generally running hot and these areas are just getting hot by association. But again pursuing that would really need someone to open it up & check the fans and heatsink are clear of fluff etc.

Heat is always a problem in laptops. By definition you've got a lotof hot components crammed in a small box. It doesn't take much to tip them over the edge.

thanks for your very useful information Grasshopper

I am wondering about the inside of the laptop and the fans myself rather than the powerpack.

thanks for your help

hello again, would I need to get the laptop looked at by a computer person or would an electrician be able to open it up? thanks

Dismantling laptops & more importantly putting them together again, is often tricky. I'd have to say that you need not just a computer person but one who is equiped to handle laptops. Even I outsource anything more than simple stuff on laptops.

But such a person won't come cheap. So I suppose there is an argument for ignoring it until something more definite goes wrong.
