PSU - Best Fault Testing method?
Hi guys,

I've recently started a computer business and I'm overwhelmed at the number of Power related problems!!

What is the best way to fault test a likely power or PSU problem?

Ive got a laptop AND a PC here that simply won't turn on, although the laptop has a green light indicating it has power.

At the moment I'm just guessing, please can you guys help me with the more professional, proper approach?

I WON'T throw my customers money around like other companies, saying :
"right you need a new adapter". (didnt work) "ok now we need a new battery" (oops)
"right now we will solder in a new DC jack... Mrs smith your total repair cost is now £350"

See what I mean? I need to fix these computers but need to do it differently to the competition, i don't like ripping people off to make money.

THANKs

Also how can I be sure its a power supply problem in the first place? A pc wont even turn on without the right cables in for example. I will note down everything said and help others on my quest for answers

Ah i see so i dont have to be using the forrums for a certain amount of time? thats what i thought i read.

Wow so i need to buy like a load of different pcs and parts.

What about with the laptop DC jacks, are most of these generic? Obviosuly power supplies are a little different in laptops lol

I'm finding it hard to turn profit with the amount of cash im already spending, on the business *sigh* i can see things are going to get even harder...

I am doing the customer service route, for sure, I do everything for my customers and ALWAYS put customer needs first, just the person I am (it infuriates me how compaines like PC werld can get away with what they charge, even when they dont actually fix the problem).

I couldn't agree more that word of mouth is the best form of advertising. I just guess im working hard and Id like some form of reward other than thank yous from customers as this is my only job (for the moment)... am I greedy? lol

I have PSUs for PCs but not laptops, think I asked my question a it wrong i may edit the post. Guuess I should have ased how to fault test laptops that won't power on even with new DC chargers. Is there only two things im thinking - bad DC jack or bad battery? How can i fault test these?

I know how to fault test a PC power supply i guess (by simply plugging my spare pcs working PSU in to the damaged PCs mobo) but i guess its the other complications im not sure about
>why is it my customers brand new PSU has failed just like the last one did, within a week etc?

Just surprised at the amount of power issues.... wow. And my customers after new builds often dont like the idea of spending +£70 on a descent branded PSU, I dont think they appreciate the problems it may solve!!
