Can anyone tell me why my HP iPAQ 6515e keeps fading and shutting off
itself when the battery level reaches 70%. but when I connect it to the
powersupply or cradle it works fine, but when i disconnect from the
powersupply or the cradle, it swithes off again, the battery level is
still in 70%. I tried hard reset and bios update, but the problem
is still exists. can some one tell me whether should I change the
battery. if soo suggest me should i buy extended or the standard
battery and also please give me the price in INR and where is it
available in Bangalore, India.
The problem is a little microswitch that tells the unit to power off when the back cover is removed... it seems to be a common problem, causing the screen to go 'interlaced' and reset or hang, sometimes shaking causes it to restore itself. solution is remove the back cover (4 torx screws and 1 philips screw under the warranty tag) and glue the switch in the up position...

I Also Had The Same Problem. Now I Fixed It. Go To Power In Settings. Click On The Advanced Tab. Uncheck The Box Which Says "Turn Off The Device If Not Used For" Box. This Will Solve The Problem. It Solved Mine. Thereafter Once, My Backlight Did Not Switch On. Fix This By Going Into Backlight Settings And Uncheck The Box Which Says "Turn Off The Backlight If Not Used For" Box. This Will Solve It. Then Soft Reset The Device To Change Settings. To Soft Reset, Find A Small Hole In The Left Hand Side Of The Device. Put Your Stylus In And PRESS ONLY ONCE. If You Keep It Pressed, Your Device Will Hard Reset. Don't Do That. Just Press ONCE.
Go to the HP.com site and get the latest firmware upgrade for your IPAQ. If you already have the latest firmware then you can probably try a hard reset which will wipe out all your files then see if it performs better from a factory reset. If it doesnt improve then theres nothing much you can do but send it to the professionals for servicing or get a new phone.
How to correct iPAQ 5450, 5455, 5550, 5555 battery charging problems / dead unit syndrome.
The iPAQ 54xx or 55xx will not power on if the batteries charge is lower than 3.2 Volts, if your battery charge falls below the 3.2 volts level your unit will not turn on, you need to plug the iPAQ into a cradle or AC charge adaptor. Note the charging light on the iPAQ will not flash at all (normally flashes orange) until the battery charge has reached a minimum charge level of 3.2 volts. You then need to perform a normal reset, then the unit should switch on normally.
HP Procedure is as follows:
To charge and reset the iPAQ Pocket PC h5400:
i) Connect the iPAQ Pocket PC h5400 to an A/C power supply. ii) Charge the battery to the minimum level of 3.2 Volts. This will take 5 to 30 minutes depending on the current charge level. iii) Perform a normal reset. iv) Power on the iPAQ Pocket PC h5400
It is recommended that you keep the iPAQ Pocket PC connected to the Universal Cradle or Cable when it is not in use.
Most PocketPC's will turn themselves on in certain situations:
- A taks reminder is initiated
- An apointment reminder is initiated
- You syncronise your PDA with your PC
These are just a few examples.
However the PDA should turn itself off after a given amount of time, unless set to do otherwise.
Go to your system settings, power, and change the time in which your device turns off. It may very well be that it's set to never switch off.
The only answer that I know of is third-party software. I have a battery monitor program that puts a battery meter down there, just like what you want. It's called "BatteryWatch 1.02" and I got it from pocketgear.com.
