My hp does no detect power plug but works on batery

Hi, First you need to establish if it is the power supply or the computer that is at fault. First, verify that the power supply is functional with a voltmeter or another computer. Second, assuming that it is OK, (always remove the battery when troubleshooting power feed problems) connect the power supply to the computer and wiggle the plug lightly all the while pressing on the power button to see it you can establish contact and start the computer. Usually the jack in the computer becomes defective when one of its wires cuts near the jack. This wire can be resoldered or the complete jack
assembly replaced.

How to troubleshoot my advent4211c for it to connect to a wireless internet network

First turn wifi on using functions keys (I think Fn+F11). A little icon will show at the bottom right task bar which will have a picture of a pc monitor with a red X symbol. Right click on this and select View available wireless neworks. Once you have that, you will see what you can connect to and simply connect. Please remember that you will always have to turn wireless on using the function key everytime you start your laptop again because for power saving it switches it off everytime you turn your laptop off

Is it ok to leave the laptop plugged in all the

Excess of anything is bad. Drainage works the best for the functioning of all batteries - even Humans :)

If it is a work laptop then you probably shouldn't care because first, you need the laptop working and fully charged always and second, the employer pays for the battery replacement anyways.

If it is a home computer, please try to fully charge it and then unplug, use and then charge again. This will ensure optimum battery performance and increase it's life.

Yes, the small battery on the motherboard is dead. Turn it over and start unscrewing all the screws, you'll find it.

I have a compaq presario 700 laptop that is no longer charging.

The notebook battery may have a defect if it will not power on the notebook and if it will not hold a charge. The battery indicator light on the notebook either does not light or always blinks orange. The notebook operates correctly when connected to the AC adapter.
A battery that will not charge may be the result of an AC adapter failure, a system board failure, or a battery failure. Perform the steps below to diagnose the failure.
Troubleshoot the power supply
To verify that the AC power supply is functioning properly, follow the steps below.

Plug the AC adapter directly into a functioning wall outlet, and plug connector into the computer. Do not plug into a power strip, surge protector or secondary power source.
Verify the following operation and take the appropriate action:
That all power cord connections are secure.
If the AC adapter connection to the notebook is loose, the connector may be damaged and require repair. Contact HP service and support for further assistance.
That the power button or power LED is lit when the computer is on.
That an LED on the AC power supply adapter is lit when plugged into an AC wall outlet (not available on all AC power supply adapters).
That the AC power supply adapter is the correct type.
Different notebook models require different AC power supply adapters. You will need to know the Product Number of your notebook to determine the Part Number of the replacement part. Click Start > HP Help & Support to view the product name, product number, and serial number that you'll need to have to speak with HP Customer Service.
View the See Also section for information about locating HP Help & Support in your operating system.

Troubleshoot the System Board
If you've verified that the AC power functions properly, troubleshoot the PC's system board by following the steps below.

Remove the battery, and keep the notebook connected to AC power.
Press and release the Power button to start the computer.
If the notebook PC powers on , then the AC adapter and system board are functioning properly. Go to Troubleshoot the battery .
If the Power LED is off , then the AC power adapter needs to be replaced. Contact HP Service and Support for further assistance.
If the power LED is on , but the notebook PC does not power on, then the notebook PC needs to be repaired. Contact HP Service and Support for further assistance.
Shut down Windows by selecting Shut Down from the Start Menu.

Troubleshoot the battery
If you have verified the AC power supply and system board are functioning correctly, troubleshoot the battery by following the steps below.

Insert the battery into the battery compartment on the bottom of the notebook PC.
Connect the AC power supply and allow the battery to charge for 15 to 30 minutes.
NOTE: The Battery Charging light should be on while the battery is charging. If it is not on, check the AC power adapter connection to the notebook PC.
Unplug the AC power adapter cord from the notebook PC.
Press and release the Power button to start the computer using only the battery as the power source.
If the PC does not power on, then the battery needs to be replaced. Contact HP service and support for further assistance.
If the notebook PC does power on, the battery is functioning properly.
NOTE: If you have purchased a second battery for your notebook PC or you have access to an identical battery, you can also check the battery by inserting the second battery into the PC and performing the Troubleshoot the battery steps again.

There was a hardware failure / problem on your laptop. If I'm not mistaken it's probably on the Memory Module.
