Yes, there is a way to do this. It's called an "inverter" and what it does is convert 12v/24v to 110v/220v - you can get them from most electrical retailers and increasingly from car parts retailers as well.

The little inverter box will provide you with one or two standard sockets, into which you can plug your notebook power supply normally.

BE CAREFUL about how long you use one without the engine running, though, as changing the voltage that far draws heavily on the vehicles battery.

My computer does not start up looks like in satnd by mode


Most All-in-One Personal Computers (PCs) are based on internal laptop/notebook component technology.

The first item to test is the Alternating Current (AC)/ Direct Current (DC) Power Adapter to see if there is:

damage or a fault in the cabling;

damage or a fault in the transformer box;

a fault, damage or a loose connection in the AC/DC Adapter Jack point via which the AC/DC Adapter plugs into the PC.

If no AC/DC Adapter-related fault is evident or any such fault is definitively resolved (such as by testing a definitively functional replacement AC/DC Adapter), then his sounds like either a Loose AC/DC Power Jack detached from or short-circuiting its Motherboard Solder Points, a Power Management problem on the Power Management Tracks, Electrolytic Capacitors or Power Management Contoller Integrated Circuit (IC)/Chip on the Motherboard or a Graphics Chip or Graphics Card damaged surface or Motherboard Solder Point Contact fault.

Any of the 3 internal faults described above would require specialist internal diagnostics, repair and testing by a technician with specialist laptop repair experience and specialist Infra Red Workstation, BGA Reballing StationMicro-Soldering, Oscilloscope, and Multi-Metering equipment.

DC Jack repairs are likely to be moderately expensive. Power Management or Graphics repairs are likely to be more expensive still, but if conducted by a professional, all three repairs should resolve the problem. A competent repair technician should be able to repair these faults and offer a minimum 3 month warranty on a reoccurrence of the same fault.

So, on the symptoms described in the question, yes. Unless it is just an AC/DC Adapter fault, this will probably prove to be a serious, non-DIY repair problem, I'm afraid.

I have a compaq presario 2200. will not power on, tried removing battery, still will not power on.


If you attempted to turn it on with your ac adapter connected and the battery off and it did not turn on then try a different ac power adapter from a local pc shop or electronics store. If it turns on then replace the adapter. If it does not then it may be the dc jack or some other internal component. Good luck!

I'll assume the computer is not in standby mode in which case the problem is most likely a power supply that has given up.

oh i see the first question was way to vauge to really answer. it sounds that this is a powered speaker meaning it requires that 12v that you are reading and wont work without it. i am assuming that the cord coming from the speaker is a male end that plugs into female if that is the case it will be difficult to find an adapter to plug into the wall as those have male ends as well. if there is a female plug on the speaker you should be able to find an adapter that plugs into the wall outlet(transformer) just be sure to match up all specs i.e. 12v 1.0a

I need to buy a power adapter for Compaq C504EA notebook.It is only 18 months old and this is the 3rd time the charger needs replacing


hi

Your best bet would be to have a look on ebay for the charger. i've posted a link. just look around a bit you will find a lot more.

As for the ac adapter frying.. looks like you have some voltage issues. use the adapter with a powerguard or power stabilizer.
