Usually a rapid blinking charge light is alerting you of a battery fault. Try taking the battery out, plugging your computer in, and turning it on (with the battery out). If it boots up, then your battery is to blame, call customer service right away and see about getting a new battery.

My hp compaq turned off by itself and won't turn on now, it won't even show the charging light when the charger is plugged in


Remove the PC labtop battery then re insert it again.
If still not charging check the charger connector if its connected as well.
If there was no problem in the charger connector,Check the charger itself.
These all what you need to check only,no problem in your labtop.
If still not charging means one of these :
1- The BATTERY may needs to be changed .
or
2- The charger may needs to be changed.

Were can I find the RCT battery in a compaq 6720s? Actualy I have forgotten my power on password. so i want to remove the RCT battery but i can't find it. can you help me please?


Laptops dont store the BIOS password like desktops meaning that even if you find the Battery the password wont be deleted since its stored on a eeprom.
best way to go is to go to compaq they will help you if you have proof of purchase

Why when i switch my hp 6720s on does the battery light flash amber then goes white nd the laptop switches off? all in 5 seconds


It sounds as if the battery is too low to power the unit on.
Firstly insert the battery. When you plug the PSU into the machine does a charging light turn on? If not then check the fuse in the mains plug as it may have blown. If the fuse is OK then you may have a defective PSU, although the motherboard could also be defective. Try a new PSU to determine if which component is faulty.
Now remove the battery and insert the PSU. Will the machine turn on or do any power lights illuminate? If power lights illuminate and the machine will not turn on then I would suggest the motherboard is at fault. If the machine turns on briefly the turns off before displaying the splash screen then I would suggest the RAM, CPU or motherboard is at fault.
If the unit works without the battery installed then it is probably a battery problem, although it is possible the charging circuit n the motherboard is fried.
Hope this helps,

Hp compaq 6720 laptop, wont charge battery, bought new battery have same problem. have tried several different chargers and they are all working, but not charging battery


If the notebook does not charge even after replacing it with new battery and checking with several chargers then it is laptop power jack issue.
You may need to replace it. However to confirm the issue is with power jack just remove the battery and try to power on the notebook only with AC adapter. If it does not then it is the power jack which is allowing the ac power to be charged.

If your notebook is in warranty then you can ship it to HP and if it is out of warranty then check the link below, you can purchase the power jack of the laptop from here.

Hi there, when I switch on my Compaq 6720s it powers up (you can hear the fan spin) then powers off immediately (LEDS go off) I have tried known good ram. Thanks


Have you checked that the power supply is giving charge to the computer, sounds like it's trying to run on battery power, but if the 'power brick' isn'rt working properly, this can give the symptoms you describe

Compaq C502US Laptop Won't Boot LEDs flash


turn it off, pull the battery from the bottom, and try it again... chances are, the power adapter is not rated properly for the notebook, or the battery is dead and won't hold a charge anymore, in which case, recycle the battery.
