Hi, try to take out the battery from the motherboard, and put it again after a few minutes. Look at the cable connector pins on the power supply, if they look straight!

Power supply is a brick with 4 pins. Total rating 19v, 9.5A. The 4 pins are two +19V and two negatives. Question. Why not use two 19v 4.74 adapters?

Feeding an electronic system computer or other devices from multiple external power supplies is not a good idea if you do not have any electronics knowledge. You would need to make sure that one does not affect the other. This is not a simple task to explain through fixya. There are a lot of things to take into account. When you mix two adapters that have their own voltage regulation control mechanisms, you never know when you hook the two of them together, what may happen. Even internal power supplies with multiple voltages do not join their outputs together. I understand why you may be thinking of doing this. Adapters with lower current capabilities are less expensive than an adapter that is twice the amperage. But trust me, you do not want to risk damaging your expensive electronic gear to save a little on the correct adapter.

Need a replacement power supply for a Evernote scanner

Sorry Gregory, gave you the wrong number.
You could try something like this. Various voltages and currents with different adapter plugs. This is on Ebay UK but I would think there are others, don't know where you are.
Ebay item number: 201154296095

1.Rated Input Voltage: AC 110V or AC240V
2.Vibration Input Voltage Range: AC95V-265V
3.Input Rated Current: 0.4-0.6AMP
4.Input Power: 90W
5.Efficiency: >88%(TYP)
6.Out Power: 90W
7.Output voltage: 15V/16V/18V/19V/20V/22V/24V(0/+0.5V NOLOAD): DC15V-24V
8.Output voltage: 15V/16V/18V/19V/20V/22V/24V(-0.4/0.5V@rating load): DC15V-24V
9.Output current: 15-20V/4.5A@22V-24V/4.0A: 4.5AMP(max)
10.Overload protection: YES
11.Short Circuit Protection: YES

What happened to my Bose Soundlink? what to do?

You probably fried your Soundlink by using the wrong adapters. In general, an adapter yields the rated output at the rated current so connecting a 19V, 3A adapter instead of a 19V, 1A adapter applied much higher voltage.

No power light around plug, but when I disconnect the AC module from the mobo, and then plug the module to the adapter, it lights up. Why?

first is the correct power pack volts and amps and watts
first first first. my guess is 65watt min..(i dont know Compaq volts its too old)
then the Fan must come on or the POWER regs are shot.
a common ***** of mobo cause
why are you fiddling around old junk parts, there is no support for this zero value PC? its only worth $5 used and broken.
your diagnosis false.,sorry.
in electronics if the voltage falls in the 2 lines from the pack.
lets say its a real HP with 19v as most are, (compaq?)
if you plug it in and the volts falls (use a thing called a volt meter and ignore useless LED that glow at 2v, see why?)
then if 19v is say 10vdc NOW, (hard fail that)

that is what? answer is 2 things.
1;bad pack (wrong pack ,weak pack or dead)
2;or the load is shorted,

facts. this is called electronics trouble shooting 101.
and OHMS laws are day 1 learning topics.

did you strip the mobo clean first. ?
there are 2 ways to do this start full and strip or start empty and build.

see this, see the parts pulled? its a complex Elitebook, one of the best made ever. not compaq relics.

we remove all modules 1 by 1, and CPU GPU last.
keep an open mind, use a voltmeter,
the BIOS is dead if cpu is pulled sure. but will still hold power.

the sad thing is seeing folks use LED for a voltmeter.
sorry that is hopeless. (2volts is useless info(@^@)
a Voltmeter DMM is $20 at walmart. buy one and learn to use it.

the PC mobo has regulator on board,
mine converts 19vdc raw to like 5 other key power rails
I have a schematic of my mobo, (rare but have it)
i can probe the rails to see if the regulator is shutting down
they do that on all overloads, all do. (this feature prevents burned up regs. a good thing)

If lucky, one h part removed from the MOBO cures the overload.
we have load bank in our shop
we can load down any power pack made or PSU
and see if it can just full power.
many cant. do to old parts you are buying
or using wrong parts,
with no parts list ?how can you fix any pc,
the parts list tells you the true packs spec, volts,amps/watts.
never assume what it came with it was right , or get FAIL endless.

BTW HP still makes learning correct packs sizes hard.
mine has 4 packs listed, for each faster power hogging CPU and GPU but does not match them up in the service guide.
just shows them. so this can get hard.
In my case only the 100w works, mine max max speed.

I seem to have a problem with the power to my computer. After 2 days of searching all kinds of forums I still haven't found a solution. The computer won't power up, no fans are spinning, not a...

First remove the power plug from the smps and press the power switch few time and wait for few minutes the re plug the power connector to the smps and switch on the computer if you still dont have power then you will have to check whether the smps work to test that its not enough to test the voltage in the 21/24 pin you will have to short the green wire and the black wire and see whether the smps fan is working if the fan is not working then the problem is with smps

Replacing the OEM 18.5 V 3.5 A ac adapter with an 19V 4.74 A adapter for my c551nr compaq, should not give me problems, will it? It should be within spec, hopefully.

Specification of Compaq Presario C551NR AC Adapter:
Power: 65W
Output: DC18.5V 3.5A
DC Connecter (Barrel) :
Internal Diameter: 1.7mm
External Diameter: 4.8mm

But it's OK to use a 90w 19V 4.74A adapter on your laptop only if the connector tip fits your laptop.

Thefollowing three conditions should be met for you to use an ac adpater safely. 1)Output Voltage is within +/- 5% of your old charger's output.
For example, ifyour old charger provides 19.5V, then you can use a charger that provides 20.5Vor 18.5V.
2) Output Current is the same or higher than that of your old charger.
For example, ifyour original adapter provides 3.42 Amps, then you can use a charger thatprovides 3.42 Amps, 3.9 Amps or higher.
3) Connector tip must fit securely into your laptop.

Computer power problem

For solving your problem do the following:
1. Check that the power cable is connected properly to the monitor
2. See that the SMPS of the CPU is working
3. Check that the power output from the SMPS is upot 12V

If not change the SMPS it may be due to failure of SMPS.

Let me know if your problem is solved and rate me as FIXYA!

Intel 865G drivers

Have you tried downloading the newest most up-to-date drivers availiable? If not I would try that first.

If that fails to work, I would check and see if there are any bios updates as the video card is part of the motherboard. However, I would think that since it works without the drivers, it would be a driver issue, not bios. When you have the drivers installed, does the video show up while booting and then fail in Windows?

You may also be hitting a range or resolution that is not supported by your TV. That being said, you could check your TVs owner manual for supported modes. If you do not have your owners manual, try setting the video card at some different resolutions with a monitor, shut down, plug back into the tv, and then restart the computer. If you find one that works, great!
