Question about HP Compaq Presario CQ60-249US Notebook
Okay, let's get to it! Hp puts a chip in the chargers they use for Presarios. If you use a NON-HP charger, the laptop always thinks it is in battery mode!! Is there a work around for this? (i.e. can you fool the presario into thinking it's attached to HP, or disable the 'battery mode' recognition?)
Remove the battery before you plug in the charger/adapter and see what it will do. It can't recognize a battery mode if there is no battery. Maybe the charger you are using is not appropriate: different voltage, wrong polarity, the tip is not in contact with the plug terminals, or the circuit is not closed to allow the passage of current.
Rocketfish, Targus , and a few others, manufacture universal chargers that work with may laptop makes and models.

SOURCE: Disabling the touchpad on HP 530
Go into your windows device manager.
Search for your touchpad (should call synaptics input device)
give it a right click and disable the device.
I rather think that your mainboard is having problems, tried a bios upgrade and the latest drivers yet?

This particular model of Hp was shipped with a bad inverter. You can
check out the link below to another forum with users with the same
In order to fix the problem you just need to discount the old inverter and it should work according to what I have read. The link to the manual is listed below.

SOURCE: hp power supply failiure
Ive worked on a friends G7000 series laptop, since it had the same symptoms you have with yours.
I tested it on my own(identical) working charger/PSU and still no charging.
After taking the motherboard out, i traced the fault to a short circuit FET (field effect transistor) with the PCB reference of PQ1, located right next to the connector for the DC power jack loom.(short from gate to source) The FET is made by Fairchild Semiconductors and its part number is FDS6675BZ. Being in the UK, i ordered the part from www.farnell.co.uk at a cost of 56pence. After changing this FET(which is there to control power) the laptop is working.
If you are not good with very intricate surface mount soldering, then i suggest you buy the component, take the motherboard out of the laptop(not too hard) and take them both down your local TV repair shop for them to check and change it(tell them the board reference PQ1).. shouldnt cost more than £20 or so been as they dont have to fault find.

If the laptop battery is more than 3 - 4 years old then the battery could be worn out. Rechargeable batteries have a finite number of charge and discharge cycles and will lose their charge capacity over time, i.e. won't charge to 100% and gradually the charge reduces until the battery won't charge up at all.
OR The battery shows a 100% charge but when the adapter is disconnected the battery drops off to zero capacity in a very short time.
If the battery drops to an unacceptable charge level then the battery needs to be replaced.
