| === 5 dot syndrome (no boot to desktop), possible reasons ===
| |
| | |
| 1/ missing /home/user
| |
| | |
| 2/ initscripts fail for hildon-desktop (happened to me when there was an error in /home/user/.profile *doh*)
| |
| | |
| === stuck orange ===
| |
| stop mce; sleep 10; start mce
| |

| === stuck usb status bar plugin ===

| === battery calibration ===
| |
| The Valid Discharge Flag (VDQ) in the FLAGS register is set when
| |
| this condition occurs and remains set until the learning discharge cycle completes or an event
| |
| occurs that disqualifies the learning cycle. A learning cycle can be disqualified by
| |
| any of the following conditions:
| |
| 1. Cold temperature: Temperature ⤠TCOMP[3:0] (°C) when the EDV1 threshold voltage is reached.
| |
| 2. Light load: A capacity learning cycle is disqualified if average current is less than
| |
| or equal to 2 times the initial standby load when the EDV1 threshold voltage is reached.
| |
| 3. Fast voltage drop: VOLT (EDV1 256 mV) before EDV1 is set.
| |
| 4. Excessive charging: Cumulative Charge >255 NAC counts (910 *Vh) during a learning discharge
| |
| cycle (alternating discharge/charge/discharge before EDV1 is set)
| |
| | |
| This boils down to: don't charge during learning cycle (self evident), do discharge with
| |
| a moderate load that's not too low but also not too high particularly don't cause load bursts
| |
| when batt voltage is about to reach EDV1 ideally you keep backlight lit, this will warrant
| |
| a proper calibration.
| |
| | |
| === battery charging current check/set === | |
| to get 500 mA from a 500 mA charger after plugging in:
| |
| * echo 500 >/sys/class/power_supply/bq24150a-0/charge_limit
| |
| you can also read that file to see how much it's willing to draw; will probably say 100 after plugging it into unsupported charger
| |
| | |
| === disable 'telephony functions' popup (for those with broken modem) ===
| |
| sed -i s/start on started dbus/# start on started dbus/ /etc/event.d/sscd
| |
| | |
| (thanks to peterleinchen https://talk.maemo.org/showthread.php?t=93158 )
| |
| | |
| === make n900 with broken screen boot and display proper image on av cable ===
| |
| put 'fbset -g 800 480 800 480 16' right before X server start in /etc/event.d/xomap (or /etc/event.replace.d/xomap )

| ==== ~flatbatrecover ====
| |
| Remove battery for 1 minute. Insert battery. Plug powered ***NOKIA WALLCHARGER*** to device. Watch steady amber. Let sit and charge. Do NOT try to boot. After 30 min, you got either
| |
| a) a booted up N900,
| |
| b) flashing amber which means you can boot,
| |
| c) steady amber shut off -> start over again with ~flatbatrecover while already searching for a new battery.
| |
| CAVEAT! Only works when ~rootfs OK (no ~bootloop)
| |
| | |
| ==== ~flashing ====
| |
| [[Updating_the_tablet_firmware]], or (on linux PC) download&extract http://maemo.cloud-7.de/maemo5/patches_n_tools/maemo-my-private-workdir.tgz, cd into it, do sudo ./flash-it-all.sh
