Hi Folks,
i guess my Xperia Pro is dying on me, it doesn't start anymore. I am actually not quite sure if this thread should really be here, as this may well be a general problem with SONY Xperia's, mods feel free to move it if so.
Here is what is happening:
Before, when i shut down the phone and connected it to the charger, a kind of BIOS screen flashed up shortly after that, showing 'SONY Ericsson' and then some simple graphics displaying the loading status of the battery.
Now, if i shut down the phone normally, these BIOS screens are not there anymore, and subsequently the phone can also not be started. Here is what i have to do get it working again:
- pull the battery
- wait for 5 - 10 mins
- connect the phone to the charger with NO battery inserted
- wait for the 'SONY Ericsson' screen, then insert the battery quickly
The phone will then startup normally. The following potential problems were checked:
- battery is fully loaded
- SD card removed, to no avail
- SIM card removed, to no avail
Phone is rooted, and has a 1 GB EXT3 partition on the SD card as ROM extension (SD Link).
Strange enough, the phone is also sometimes not correctly recognized on my laptop. If that happens, also SONY's support program for Windows, called 'PC Companion 2.0', is unable to connect to the phone when on USB.
What could that be ? Is my battery dying on me ? That's highly unlikely, because the phone is only 3 months old and i can run the phone for 3 days without recharging, if necessary (Thanks to root, removing facebook and the like, and the app 'SetXperia').
On the other side, the missing recognition from my Laptop would most likely indicate a problem with that BIOS being loaded from the ROM, no ? Do ANDROID phones even have something like a BIOS ? If so, is it made by the phone manufacturers ?
Thank you for helping me out, as i have rooted the phone i can not easily send it to service.
Regards
Christian
ADDENDUM / 0% battery problem related :
It may so happen that my problem is somehow related to the fuel gauge problem reported in this thread here, but i never experience a 0% loading state ? My batter never goes lower than 30% typically, and the restart problem will also happen if the battery status was showing 98% when i am shutting it down. However, it seems that the guys suffering from this do have a similar problem, i.e. the KERNEL not booting when they try to switch on the phone ?
Is it possible that some hardware part in the phone checks the status of the battery, detects it as too low and refuses to start-up, even though the battery is actually full ? But then, why doesn't it start with battery inserted when i connect it to the charger ? I first have to pull the battery, then it will start ?
ADDENDUM 2 / Power Saving App SetXperia messing with CPU clock:
As mentioned above, i am using the app 'SetXperia' to save battery. In 'default' mode it will constantly vary the CPU clock according to real need, in order to save on battery. Can this app confuse the fuel gauge, and my battery show it is fully loaded, while in reality it is almost down ?
