Cum se verifica starea de sănătate a bateriei ?
Rolul unui laptop este acela de a fi un computer portabil, și când zicem portabil ne gândim automat la baterie. de aceea este extrem de important sa stim cum se verifică sănătatea bateriei.
Tehnologia în ultimii ani a evoluat extrem de rapid, dar parca bateriile au mers ceva mai încet; În ciuda capacităților mai mari ale bateriilor LIPO, acestea au rămas cu același număr de cicluri încărcare descărcare (Charge Cycle Count).
Din aceasta cauza bateriile dispozitivelor mobile tind sa nu mai păstreze cantitatea de energie pe care o păstrau la început.
Unii zic ca-i bine sa scoți bateria din laptop !
Dacă stai sa te gândești ar fi o idee buna, sa păstrezi bateria în sertar încărcata, atunci când folosești laptop-ul acasă, și sa cuplezi bateria doar atunci când pleci și ai nevoie de mobilitate.
E logic, ferești bateria de încărcarea de tip float, care tinde sa păstreze bateria la un anumit nivel.
Producătorii însa spun ca nu-i nevoie sa decuplam bateria, ca aceste baterii au un management de încărcare smart, care nu supraîncarcă bateria.
Totuși, sa zicem ca-i o idee buna sa scoți bateria, din păcate în ultima vreme din ce în ce mai multe laptopuri vin cu baterie interna, ca la telefoane, baterie care nu poate fi scoasa chiar atât de ușor.
Cum aflam cât de sănătoasa mai este bateria din laptop ?
Am găsit pentru voi cea mai simpla metoda de diagnosticare a bateriei de pe laptop sau tableta cu Windows.
Nu trebuie sa instalați softuri terțe.
Cum se verifică sănătatea bateriei ?
Folosind Powershell, dam comanda:
powercfg /batteryreport
În C:\Users\”userul curent” veți găsi raportul în format html, pe care-l deschideți cu orice browser web

Despre Cristian Cismaru
Salut Cristi,
Detin un Notebook Alienware 17 R5 cu un sistem de operare windows 7, nu imi doresc inca trecerea la windows 10 ce comanda sau ce program as putea folosi sa vad ce durata de viata mai are bateria acestuia?
Multumesc,
Cu Stima Gabriel.
Da e foarte utila. Felicitari pentru tutorial. Dar pe Windows XP cum se face? Eu am Windows XP la un laptop vechi de vreo 12 ani si as vrea sa vad starea bateriei pentru ca ma tine doar 30 de minute.
Cum se face pe Windows XP.
in win 7 nu merge
Pentru Windows 7 ,lansam cmd.exe cu drept de administrator ,introducem comanda powercfg -energy sau powercfg/energy, dupa cateva secunde ar trebui sa genereze un raport.
Super fain. Multumim frumos.
Salut , la ultimele laptopuri cu procesoare de ultima generatie nu cred ca mai porneste daca scoti bateria. Am incercat la al meu , un ROG cu i7 8750 si nici nu vrea sa se miste, parca ar fi mort . Cred ca e o masura de siguranta “scrisa” direct in BIOS . De pornit si apoi cu el pornit sa o elimin , nu am incercat . E inca in garantie ,nu vreau sa patesc vreo minune .
Bafta !
Salut Cristi
Foarte utila aplicatia, insa vreau sa te intreb daca se poate face ceva asemanator si pe bateria telefoanelor mobile?
Ar fi bine de stiut atunci cand cumperi un telefon second hand si nu numai. Poate o sa faci un video si pe tema asta.
Multumesc
S-au poate exista o apk. si ne-o poti spune.
bateria pe laptop este 88% 3 linli
Salut Cristi am un laptop Asus F 555 LJ am schimat bateria veche cu una noua se inarca cea noua la maxim dar dupa o perioada de folosire a latopului pe baterie ecranul incepe sa pilpaie .
O seara buna .

Usage: POWERCFG -QUERY
(optional) Specifies the GUID of the power scheme
to display, can be obtained by using powercfg -l.
(optional) Specifies the GUID of the subgroup
to display. Requires a SCHEME_GUID to be provided.
