I've lost the power supply (charging capibility) for my Fugi F700. Can I buy another?

Charger go true a lot of power voltage regulators and in the end is not powerful inought to power loptop without battery, same capasity neaded to help maintain stable curent.

4 possibilities.
1 The Compaq f700 power supply is duff. How do you know it is actually working? Have you been able to test it on another system?
2 The charging circuits in the laptop have failed. Only a workshop can test this.
3 The Battery is dead. How do you know it is good if the system is not working?
4 There is a mechanical connection problem. Damaged lead/plug/socket etc. Examine and swap out to check.

Note that the system would not work if 1, 2 and 4 were the problem. (Since the system should still work of AC even without a battery).So a battery problem is the lowest probability.

You need to print this out-on someone else's computer. Hope it works for you!
Remove the battery and charger/ac adapter/power cord from your Compaq Presario F700 laptop, press and hold the power button for 20 seconds to discharge any residual current inside the Compaq Presario F700 . This clears your RAM and is like a hardware reset. Replace the battery and charger/ac adapter/power cord and turn your Compaq Presario F700 laptop on.

Boot in "safe mode". As it starts up press F8, the computer ask you if you'd like to start in safe mode. Highlight "safe mode" and press enter. See if your laptop is booting up ok .

If your Compaq Presario F700 boots ok, do the following,

Try System Restore first,
Start Menu->All Programs->Accessories->System Tools->System Restore. Choose the most recent date before you the encountered problem. If it doesn't work, try the next date.

If System Restore does not fix it, as a last resort, you might need to fdisk, reformat your laptop hard disk clean and reinstall OS, that usually fixes all bugs. Before going that route, try following,

Uninstall unnecessary programs and applications.

Scan with a antivirus program

Scan with a spyware/malware program

If the problem persists, did you check if it could be your Compaq Presario F700 laptop power cord or power source problem? Defective or insufficient power supply might cause error messages that are misleading. Take the battery out and power on your laptop with the charger only. Make sure your Compaq Presario F700 power jack and charger plug tip are securely connected. Did you notice the power jack loose? You can find laptop power jack on ebay. Fixing and soldering the power jack requires professional skill though. The charger green/blue LED should be on. If not, replace the defective charger. Compaq Presario F700 laptop battery charger, especially its power cord/cable, lifespan is limited and does not last forever, consider buying a lifetime warranty charger online from company like www.topmic.com

Having gone over a month without a reply to my query, I assume my suggestion to use a card reader eliminated the need for a cable.

Remove your battery and try with external power supply again if it boots up all good and proper then after booting to SOE refitt the battery and let it charge - if it doesn't boot or power on look to see if the blue LED it on around your power input point. If there is no illumination around the power input port try another 65w power supply input - your power pack may be dead. Cheap fix - if it still does the same powers on then off - you have reason to go out and buy a new laptop - would be cheaper than replacing the M/board
trust me.

Could be a number of things, related to the power supply. However if there are any lights on then it is likely to be a motherboard problem. Contact a local PC repair shop. I had a simiar problem and it was the on board video card. They should not charge to diagnose the problem. Mine cost £80 to fix at PCZone, Birchwood.

Yep, the power supply input to the laptop is gone - the external input shorted out. You may find that the Compaq repair charges almost equal a new one.

Assuming you have checked the the power strip or outlet by testing it with another electrical appliance to see if it is in operation, you can test
the power supply to the unit with a tester or oscilloscope. If it still does not work then check the cable that plugs directly into the unit and replace it if necessary. You can also open the unit to check if the cable is attached properly to the motherboard.

try to jump green and any black wire from the power supply...if the fan dont work..power supply is damage..need to change..

Replace the charger with the correct one.
