Problem with startup 6515 - need advice

[commanddos]

Chaps

Yesterday my 6515 stopped cooperate with me! Totally!
- I didn't dropped him or physically damaged,
- The battery was charged in 85% just before it was switched off itself
- Back cover closed with no gaps between cover and body
- Was fully functional when suddenly switched off
- I didn't upgraded anythihng before.

Symptoms:

- Ipaq is not reacting on start button
- Not reacting on reset
- Not reacting on hard reset
- The left diode blinking red during charging via usb cradle when I’m pressing power up button
- The same happens with regular charger
- During charging with regular charger when I’m opening the back panel the diode stop blink and become flash continuously in red.

I have already tried almost everything to start it up:
Changed the battery,
Open, close the back battery panel
With and without SD card

Appreciate any HELP!

Ok I have made some progress..

:cool:Now I can see the bootloader screen and that's it. :cool:
What to do next ???:cool:

Im not sure what blinking red means but when you remove the backcover, the red led will lite up.

Try to do a hard reset, and see if it restarts without going to bootloader. Otherwise, you will probably need to upgrade the firmware from the bootloader screen. Download the latest rom updates from hp.

Thanks for reply
Indeed! When I opened back cover the led become flash continuously!
I have tried to apply the rom update from HP unfortunately all of the updates have to be done through Active sync!
It is impossible in current situation because of pressing Power+Joystick+Reset the ootloader screen appear but then nothing This is happens only when PDA is charging with regular charger. Using USB charge or battery power I can't even start the bootloader screen.

From where can I download the SD bootable image or how to make it?

Hi

And again small step ahead:

In craddle there is another input for power so I managed to power it up and connect.

I had to switch of firewall (otherwise i have error 601 - unable to connect the device or something simmillar) and reinstall Active sync back to 3.8

Got bootloader screen USB and hp logo and v 021
by running romupdate utility downloaded from hp site ( whatever the version is ) I finally recognized my model version: it is 6515c :eek:

Next
Found valid version from HP site for 6515c ( i think 1.21) and successfully upgraded. No breaks, no other issues just successfully uploadede into finish.

Then hard reset and......

The system starts, screen flashes up, system start loading and the screen fading out. ... and again ..... and again ...... and again and the nothing!

I have tried again to pull out back cover, remove batery, put it back after some time, place back the cover and again.

Nothin' Nada Null %$#@%!$#ing piece of junk.

BTW it is happening only where PDA it is connected to AC power. On battery system is not booting, no booloader nothing!:mad:

:confused: Any suggestions? Pleeeeeeeease! :confused:

[cluurk]

After you upgraded the firmware and it started up, was this done with the pda on AC or battery power? If its on battery and it starts fading, your battery is probably screwed. Did you also know there are 2 batteries in the IPaq?
Oh and if its a battery problem, you will need to leave the battery+pda connected to the AC for a while before it can startup and probably into booloader. Run your firmware upgrade again and power it on with the AC connected! If it boots up fine, then monitor the battery status bars in the Power settings and see if both the LiIon and NiMh batteries are holding charge. Hopefully from here you can find a dead battery.

Another thing you could try is to reset the battery when in bootloader mode once you are certain its the battery

Hi
I really appreciate your response.
The whole upgrade and the other stuff have been done with inserted battery and AC connected.
I plugged the PDA into the cradle which was connected to PC via USB and I plugged also AC into the cradle AC input.
It is fading just after reboot only when the iPAQ is connected to AC power (of course battery is inserted otherwise it will not startup anyway.)
On pure battery power it doesn’t giving any signs of living whatever button has been pressed.:confused:

The link you provided might contain very valuable directions to me. The man is learning within whole life and dying still being stupid. :p
I thought that I read the info from the site you suggested but I probably missed the meaning of the post regarding battery reset. That might be this. I will check and update you very soon.:)

[commanddos]

:mad:
I did the steps from above link. The iPAQ rebooted, started to load the os and again faded out….
Question to everybody:
During bootloader screen appear should I have any diode flashing blinking or whatever:confused:

I’m asking because of mine is blind!:mad:
Nothing is flashing, blinking, beaming or shining. Just two, completely dead diodes.:cool:

[cluurk]

Hi, I've just found out what flashing red means

"green blinking means GSM coverage, yellow blinking - missed reminder or alarm clock signal, permanent yellow - recharging, green - the battery is full, red blinking means greatly discharged battery, pale blue blinking - Bluetooth is on"

I think one of your batteries is dead, and if you have already replaced to LiIon battery then you'll probably have to try to replace the NiMh one inside. I cant think of anything else to try

[commanddos]

Damn!
I think I have a hardware problem! I have 2 batteries: one brand new and the old one. Both not working! Moreover they're not charging! They suppose to charge when I put PDA into the craddle or directly plug to AC charger but they aren't.

No diode is flashing during charging. Damn.

I will try to borrow one battery from one of my friend just to check if this is it!
I will let you know later on.

[cluurk]

If I recall correctly, the charging led does not light up in bootloader mode. I maybe wrong though. I think you should try to check the voltage in the LiIon battery to determine if they are being charged.
Also you never mentioned checking the backup NiMh battery. I believe that the NiMh battery is required to power up of the ipaq as well so it may be the cause of your ipaq dying after starting up.

[commanddos]

Fortunately I know someone who can charge the battery for me. There will be no problem with that.
From the other side I'm worry about the phone charging....
Why I can't charge the battery using iPAQ?

Next you mentioned about "NiMh battery". I'm sorry for my ignorance but what is that?
Is it secondary battery ?????
Is there any way to charge or replace it? Is it pluggable battery? Where is located?

[cluurk]

Yes there is a secondary battery. However, I do not know where it is either.
Here is an example from a different PDA

If you want to open up your IPAQ do it at your OWN RISK!

You don't need to touch that one, this battery is designed for save your data when you exchange the main battery.

Commadnnos,

Sound like your 6515 has battery charging problem. If the charging failed, even you have brand new battery, it won't be charged at all.

Since you have two batteries, you might want to buy a external battery charger to prove those two batteries are good.

I think the charge circuit is in the second PCB board which under the keyboard inside your 6515; if those batteries are good, you might want to buy a dead 6515 and replace it by yourself...

Cheers,

Well Well Well ..... it is getting wormer. Many thanks to everyone who are still trying to help me out. Thanks again.

Is that mean the secondary battery is located under the keyboard? I saw the photos from unassembled 6515 and it looks like the secondary battery. To replace it you have to first remove 3 screws, unplug the LCD and remove whole main board.

Is that means that the charging circuit has been built in the keyboard plate?

[commanddos]

I would like to thank everyone for help. I think we can close this thread over here.

My beetle just went out into the "digital heaven". :(
The HP support specialist ensured me (without any tips or hints from my side) that mainly there is a problem with passing the power from the charger to the battery which means no more no less like ".... dude your motherboard is screwed. You have to get the new one or whatever...!":(
So now it is a time for selling the rest of the parts on auctions......

R.I.P (Rust In Peace)

if the red light blinks
1 your battery has problem
or
2 your battery cover has problem. The plastic part on the back of your battery cover may have broken which touchs the microswith on the mainboard.
if that microswitch is not triggered , the hw65xx,hw69xx will not turn on.
