Dead compaq cq40 laptop no power no charging


Step 1:
If your laptop charger seems broken, it's most likely because the battery will not charge. You plug in the cord, the lights come on, but the charging light doesn't change or blinks repeatedly. When you remove the power cord, the laptop shuts off instantly due to the depleted battery. There's more than one cause for this, and it's not always a broken charger.

Check the connection between the charger and the laptop. It should fit firmly in the DC jack without wiggling. If it is loose, use electrical tape to hold it in place so the charger can receive power. This is a temporary fix, however, because a faulty connection can create sparks and cause a fire or injury. A loose connection will just get worse over time, so have it sent to a DC jack specialist as soon as possible. Turn off the laptop and flip it upside down. Locate the latch that secures the battery and slide open. The battery should pop out; give it a tug if it doesn't. Apply a small amount of rubbing alcohol (Methylated Spirits)to the tip of a cotton swab and use it to clean the battery's connectors. Dirt can build up and interfere with the connection, giving the appearance of a broken charger. Let the alcohol dry completely and re-insert the battery. Slide the latch to secure it and plug in the power cord to test it. See if the laptop powers on with the charger only and battery removed. If it does, the battery is the likely culprit and should be replaced. If the charger is truly broken, the only thing to do is to replace it or the power cord attached to it. Look on the bottom and write down the part number. Call the laptop manufacturer for a replacement charger or search for the part number on eBay. If you purchase from anyone other than the original manufacturer, ask for genuine parts to reduce the possibility of problems. Troubleshoot Mag Safe adaptors

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

I have a compac presario cq60, I've recently got a brand new charger and battery both from hp as they both needed replacing. I've put the new battery in and plugged the charger in but I noticed that the...


First thing to check is that the battery is inserted properly. Take the battery out, make sure there's nothing on the contacts, and then put it back in. The problem could also be that the charging jack on your laptop is loose. If you hold the charging cable plug in the laptop with a little (not a lot) force, or push it a little to the front or back, does it stay charging? If it does then the jack is loose. Your temporary fix is to hold it the way you did while testing to see if it was the problem. Be aware, this fix is strictly temporary, eventually the jack will get loose enough and not make contact at all. Consider calling Compaq customer service and checking to see if it's covered by warranty.

Compaq Presario 1200 won't charge battery


dear N9YK

you can follow this

If you have a loose connection where you plug in the power on your laptop, or it works intermittently, you could have a bad dc jack. Symptoms
  • Move the power plug and the laptop loses connection
  • Broken or cracked dc jack
  • Laptop won't charge but worked on battery
  • Power LED and battery LED flicker when the adapter tip is moved
  • Battery won't charge
  • Sparks come out the back of the laptop
Why does this happen?
  • Flaw in manufacturer designs
  • Use of universal or non-original ac adapter
  • Lots of plugging and unplugging of the ac adapter
  • Tripping on or pulling the ac adapter cord
or you can check your dc amper in your adaptor

oke



thx
