Test or Replace your PSU then test all leads that are attached to your hard drive sounds like a faulty lead of some sorts then
try replacing all the leads that attach to your hard drive including electrical extensions + IDE,SATA and the ones that attach from your motherboard to hard drive
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty or just replace them they are probably old and faulty because a computer has to have an end to the circuit any fulty leads will lead to no boot up
good luck

WE CAN NOT USE OUR CASIO KEYBOARD NOR FIND A POWERCORD #AD12ULWK1630 anywhere


Hi, This is a copy and paste from a similar question, please excuse my laziness........

Hi, There are several common reasons why this and most similar keyboards have this problem.
If you can fit known good batteries, and it works, this confirms the problems will be with the external power supply or connection.
Usually batteries are not available, so.......
Do the obvious.
  1. Is the power supply plugged into a known good mains socket?
  2. is the mains socket switched on?
  3. is the power supply plugged into the keyboard?
  4. is the keyboard switched on?
If the power supply is not the one supplied with the keyboard, then check it is compatible.
(You do not have to buy an expensive replacement power supply, a universal, regulated one, with a selection of connectors will be fine. Supermarkets and the like sell them.)
The manual, or a label on the bottom of the keyboard will tell you the voltage, current consumption, and whether the current is AC or DC.
Invariably the current is DC.
All the Casios I have are 9 Volts, (9V) and very few are more than 300 milli amps (300mA) More milli amps is fine, so the current can be the same or greater.
A TYPICAL power supply is likely to be:-
  • 9 V
  • 300 mA or more
  • DC
BUT DO CHECK
Important
The power supply needs to be REGULATED.

Polarity
This is the way round the connector is wired.
Usually the center is negative (-) and the barrel is positive (+)
This information is molded into the plastic or on a label next to the socket.
On a replacement (universal) power supply, there will be a set of connectors, and when you have selected the correct one, the arrow on the end of the lead should point to the correct polarity symbol on the connector.

Fault finding
The most common fault is the power connector being broken or the solder has been broken.
Slowly moving the connector round, to find it works in some positions, is a sure indication that is the fault.

Repair is quite simple, but there are a lot of screws to take out.
Ideally, drill a hole in the case, where convenient, and fit a metal connector. Now connect to the PCB, in place of the original socket, with flexible wires.
Other wise if it is just solder failure, re solder and glue the socket with epoxy resin (Araldite) or hot glue from a glue gun.
Hope this helps, Chris.

Could be a bad battery and/or charger/AC Adaptor/DC Connector. Try to isolate the problem by removing the battery and then plugging the laptop charger in and starting the pc up. It should boot on the AC adapter alone. If it won't boot on the AC adaptor or it flickers and flashes while on the AC adaptor, I would first suspect the AC adaptor or the DC connector on the laptop (try wiggling the power plug at the PC to try and check the connector). If it behaves while on the AC adaptor without the battery present, I would suspect the battery. Either way, you may have to replace something.

The laptop probably isn't charging. Could be a bad d/c connector on the laptop or the battery is bad. Remove the battery and plug in the a/c adapter and see if it powers on. Wiggle the a/c plug in gently while pressing the power button on the laptop. It powers on and off briefly then I'd say it's the d/c jack on the laptop, bad sodder joint.

AC adapter power connection LED blinks but not charging


This suggests to me that you need to check out the AC adapter, and see if there is an intermittent short. In otherwords a break in the wires.

AC adapter unplugged from laptop, and power, remove the AC power cord from the body of the AC adapter.

Use a multimeter set to OHM's, (1K), and connect the Positive (Red) probe lead to one of the flat bladed prongs, in the power plug that plugs into the surge protector.

Touch the Negative (Black) probe lead to one of the holes in the plug, that goes into the AC adapter 'body'.
Keep going from hole to hole, until you get a reading.
Now have an assistant gently wiggle the power cable, and see if you get an intermittent reading.

Do the same for the other plug's flat bladed prong.
Intermittent reading means replace the power cable, or if more feasible, the entire AC adapter.

Power cable proves to be fine, move on.
Plug the power cable back into the AC adapter. Plug the AC adapter into power.
Using a multimeter set to DC Voltage, touch the Positive (Red) probe lead of the multimeter, to the center hole of the plug that goes into the laptop.
(If just a symbol, the DC Voltage symbol is a dotted line over a solid line)

The Negative (Black) probe lead, touches the outside cylindrical metal shell, of the plug.
Have an assistant gently wiggle the cable, and see if there is an intermittent reading on the multimeter.
(Reading should be 18.5 Volts DC)

[There are Analog multimeters which have a scale, and a needle, and Digital multimeters that just have a digital readout.
If using an Analog multimeter the needle will drop towards 0.
If using a Digital multimeter the readout will drop to smaller numbers, or 0 ]

AC adapter checks out? Go on.

The port on your laptop where the AC adapter plugs in, is the DC Power Jack.
AC adapter unplugged from laptop, Battery removed.
Take a pencil, and gently use the eraser end to see if you can wiggle, the center pin of the DC Power Jack.

ANY perceptible movement means a problem with the DC Power Jack.
The GOOD news is that the DC Power Jack, is NOT soldered directly to the motherboard.

It slides down in a Channel on the outside edge of the Base Enclosure, and has a wiring harness coming from it.
The end of the wiring harness has a plug, that plugs into the motherboard.

The HP part number for this DC Power Harness is HP 600630-001

This is a link to a free Service Manual from HP Support,

http://h10032.www1.hp.com/ctg/Manual/c02627955.pdf

Page 73 is for the Power Connector Cable.

No damage to the DC Power Jack, and the harness is not slightly unplugged?
Now you have real problems.

You have a bad Power MOSFET,

A) MOSFET:

B) Power MOSFET:

C) http://mayohardware.blogspot.com/2010/04/important-parts-on-dv6000-and-dv9000.html

However it doesn't take a rocket scientist to replace. (Sorry Gort)
These SMD's use a J-lead contact. Simple unsoldering, and soldering.

(Better be fast though as you don't want to overheat a power transistor. Better be good, because you don't want any cold solder joints)

Lenovo laptop(8932) will go into a sleep like mode (you can still see the screen, very dim) when plugged into ac adaptor. Doesn't do it with battery power. Changed system board, power adaptor - no...


Good Day Psmith!

It looks like the AC adaptor is not making the right supply voltage needed for your laptop.

If you have a multi tester, you can test your ac adaptor to see if it has stable 20V voltage output supply needed for the laptop to make it work.

Set your tester to DC range. Plug the ac adaptor to your wall socket. Hold the other end of the ac adaptor (the one you connect to your laptop. Insert the red (positive) lead into the center of the adapter pin, then touch the black (negative) lead to the outside metal part of the pin.

Read the display in your tester. If the adapter is working properly, the meter should read between 19 to 20 volts of the rating. If the adapter is faulty, the meter will read below 18volts.

If that would be the case, I'm afraid you will need to replace your ac adaptor.

You can purchase online a replacement ac adaptor for lenovo 8932.

1. From this site, it costs $34.99 + $8 https://www.ebuybatteries.com/product/models/2_IBM-Lenovo-AC090W008T15_IBM+Lenovo+ThinkPad+R61+8932.htm

I lost my GE Ultrasonic 2.1 Speaker power adapter and i need need ones but i dont know what to buy, the voltage it requires..6 or 9 volts?


at most electrical stores you can buy a universal power adaptors with a selection of socents to fit most connections. and which has a selector on it for various voltages settings.
take one of the little connectors and see which one fits. then checking the polarity on your device set the polarity the same when plugging the connector into the power supply cable. adjust voltage as needed.

Warning: when connecting a variable power adaptor alway connect on the lowest voltage setting and work up as too high voltage can distroy your appliance.

if the touchpad is working fine with the battery and if it is not working with the ac adaptor then in this case u can try with the different ac adaptor and still if it does the same thing then uninstall and resintall the toouchpad driver and restart the computer and still if it does so with the ac adaptor then u need to open the laptop chasis and then u need to fix up the power supply connector in the motherboard where the power supply from the ac adaptor is not getting the adequate response from motherboard.
