hp 5550 oziveni dlouho nepouzivaneho pda
Koupil jsem 5550 pritelkyni na navigaci(ve spojeni s BT gps). Bohuzel ho slecna delsi dobu nepouzivala a pda nechce naskocit, kdyz ho dam do nabijecky, tak nesviti zadna ledka proste kus srotu. Neznate nekdo nejaky trik, jak ozivit delsi dobu nepouzivane pda? Pripadne jak provest nejaky Tvrdy restart stroje?
Dekuji za kazdou radu.

Delší dobu je co? Měsíc, sto let...?
Zařízení asi bylo použité, tedy může být baterka po smrti. No a v neposlední řadě, pokud dobíjíš prázdné zařízení, musíš přímo nabíječkou, nikoli přes USB, ten to neutáhne.
Hard resetem se už teď nic nezkazí - návod zde.

Diky za rady. Hardreset jsem zkousel (podrzet dve spodni talcitka a zaroven drezet stylusem reset po dobu vetsi nez 5s). Zarizeni jsem videl naposledy v provozu v dubnu. Zkusim na noc vyndat baterku, ale tusim ze budu muset koupit novou baterii.

Tento problém jsem řešil několikkrát, dělá se to tak:
1.) dáš PDA na nabíječku aby se baterie trochu nabila (naposledy jsem ho tam měl 4 dny, než to naskočilo)
2.) stiskneš dolní dvě klávesy, ťukneš do resetu, pustíš spodní dvě klávesy
3.) dáš PDA do kolíbky, nejlépe se zapojenou nabíječkou
a PDA naskočí
ad bod 1.) v manuálu je psáno něco kolem 5 minut, ale mě se naposledy stalo, že to PDA naskočilo opravdu až po 4 dnech, asi podle stavu baterky
To že PDA nebliká je v pořádku, blikat začne až ho daš do kolíbky (bod 3.)
