Hp r707 wont turn on

Replace the batteries. If they won't hold a charge, they're toast. All batteries wear out eventually, chargeable or not. You might also check the battery contacts for corrosion -- remove any with a small piece of fine snadpaper and blow out the battery compartment with compressed air.

Ifthe laptop battery is more than 3 - 4 years old then the battery could be wornout. Rechargeable batteries have a finite number of charge and discharge cyclesand will lose their charge capacity over time, i.e. won't charge to 100% andgradually the charge reduces until the battery won't charge up atall. ORThe battery shows a 100% charge but when the adapter is disconnected thebattery drops off to zero capacity in a very short time. Ifthe battery drops to an unacceptable charge level then the battery needs to bereplaced.

My suggestion:
You need a new laptop charger with suitable voltage for your Acer Notebook.

If it works only when connected to the charger, the battery needs to be changed.

Try to connect it to the charger. If it works while connected to charger, you need to replace the battery.

if you can test the battery seperately do so. i favor using a voltmeter.

Make sure the battery contacts are clean. The rechargable batteries looses their charge even when they are not in use. It is important to fully charge the first time the rechargable batteries.

i have the same problem,, and i just talked with the supportgroup of hp,, and he told me it is the ccd chip,, it is broken, and you can get it fixed,, but it is cheaper for you to just buy a new camera,, hope i helped ya,,

don't know if this will help,

I had this same problem a couple of months ago, battery appeared to be charging but got emptier and emptier, tried different chargers and no improvement etc.

Friend has same phone, used their battery in my phone which was charged and phone was working fine, meanwhile, charged my battery in their phone and it charged fine and then for 2 months no repeat of the problem...

then last week, it happened again, trouble is this time i'm on school holidays and can't use the friend's phone for another 3 weeks!

I've just spent 30 minutes on the phone (premium rate) to HP re this problem. The solution was as follows: switch the camera off take the battery and any memory cards out press the end of a paperclip into a small hole (which you can see with the battery compartment open) remove the paperclip after 10 seconds put the battery and memory card back in and the problem should be sorted. HP also suggest upgrading the camera firmware (which you can do via their website)
