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.

Hi. Try to drain the electrostatic energy of the motherboard. Please see procedure below.

Take out the battery
Unplugged the power adapter
Push and hold the power buttong for 30 secs

Compaq Presario F700 Won't Turn On


Assuming the unit is plugged in, this could be an issue with the power supply, or an issue where the cord connects to the laptop. If the power connector on the back of the laptop is secure / doesn't feel loose or damaged, you may want to simply get a replacement power supply from a local electronics store. Be sure to take the make and model information of the laptop and the power supply with you to the store.

My compaq f700 laptop won't boot up


Here below are possible causes and troubleshooting steps of laptop that can't power on, hope it may help:
Possible causes:

1. AC adapter failure.
2. Power jack failure.
3. Motherboard failure.

Possible troubleshooting steps and repair solutions:
1. Test the compaq f700 ac adapter with a digital multimeter. It's possible that you have a failed AC adapter. If you don't have a multimeter, test your laptop with another known good AC adapter.

2.It's possible that power jack (socket where you plug the AC adapter) is broken. Remove the motherboard and take a closer look at the power jack. In some cases you can fix the jack by resoldering it on the motherboard. In other cases you have to replace the jack with a new one. Using a multimeter, test if the power goes to the motherboard through the jack.

3. If replacing the AC power adapter and jack on the motherboard doesn't help, most likely you have a bad motherboard. Replace the motherboard.

My compaq is power on for 2 second and off , how to fix is thank you


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

DEFRAG C:

CHKDSK C:

Clean up and repair registry problems with registry repair software of your choice

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

Hp presario f700/f750us, cd/dvd player, won't boot from start up but is listed first in boot order, not recognized by windows either, won't read, write or play. tray opens and light blinks. tom...


Check the jumper settings in the back of the drive, by the power cable. Make sure your cd/dvd drive is set to SLAVE, with your primary harddrive as MASTER. Check BIOS settings, specifically your boot order, choose which drive you want to load first (usually HD 0), save and exit.
That's just the basics, though.
Another possibility is that you might just have a paperweight ;)
If so, try another drive.
Hope that helps

Compaq F700 Battery live very less


Giri,
Its normal, generally it comes with 80-90 min. You can use HP Power management to optimize the use of battery. Making screen less bright will increase the power backup.

Thanks
