Laptop se ne pali bez cmos baterije

Dobio sam neki laptop za pregedat, neki stari acer s i7 6gen, tipkovnica mu ne radi vec 3 godine, ali je power tipka radila iako je smjestena na tipkovnici.

Nego, zenska je sama isla mijenjati bateriju i slucajno udarila u cmos bateriju i otkinula ju, na ploci nije ostao ni kontakt vec je i njega otrgnulo tako da laicki ne vjerujem da se to moze nazad zalemiti.

Pitanje je: da li je moguce da se laptop ne pali tj ne daje ama bas nikakve znakove zivota jer nema cmos bateriju ili se poklopilo da je power tipka krepala bas sad kad je cackala?

Jedino se upali lampica od baterije kad spojim strujni adapter dok je, naravno, baterija spojena.

Trebao bi dati nekakve znakove života.

Baterija je tu samo za BIOS settinge i storanje/reset istih.

Vjerohatno je pcb zbog gustoće višeslojan ... kad je odvalila cmos bateruju očito je bila nježna i pitanje šta je još stradalo.
Neka ide šlepere iskrcavat.

Ako je uspjela bateriju skinuti, vjerojatno je pokupila još poneku komponentu, treba detaljno pregledati ploču...

But there’s a reason. There’s a reason. There’s a reason for this, there’s a reason education sucks, and it’s the same reason that it will never, ever, ever be fixed. It’s never gonna get any better. Don’t look for it. Be happy with what you got. Because the owners of this country don't want that. I'm talking about the real owners now, the real owners, the big wealthy business interests that control things and make all the important decisions. Forget the politicians. The politicians are put there to give you the idea that you have freedom of choice. You don't. You have no choice. You have owners. They own you. They own everything. They own all the important land. They own and control the corporations. They’ve long since bought and paid for the senate, the congress, the state houses, the city halls, they got the judges in their back pockets and they own all the big media companies so they control just about all of the news and information you get to hear. They got you by the balls. They spend billions of dollars every year lobbying, lobbying, to get what they want. Well, we know what they want. They want more for themselves and less for everybody else, but I'll tell you what they don’t want: They don’t want a population of citizens capable of critical thinking. They don’t want well informed, well educated people capable of critical thinking. They’re not interested in that. That doesn’t help them. Thats against their interests. Thats right. They don’t want people who are smart enough to sit around a kitchen table to figure out how badly they’re getting f*cked by a system that threw them overboard 30 f*cking years ago. They don’t want that. You know what they want? They want obedient workers. Obedient workers. People who are just smart enough to run the machines and do the paperwork, and just dumb enough to passively accept all these increasingly shittier jobs with the lower pay, the longer hours, the reduced benefits, the end of overtime and the vanishing pension that disappears the minute you go to collect it, and now they’re coming for your Social Security money. They want your retirement money. They want it back so they can give it to their criminal friends on Wall Street, and you know something? They’ll get it. They’ll get it all from you, sooner or later, 'cause they own this f*cking place. It's a big club, and you ain’t in it. You and I are not in the big club. And by the way, it's the same big club they use to beat you over the head with all day long when they tell you what to believe. All day long beating you over the head in their media telling you what to believe, what to think and what to buy. The table is tilted folks. The game is rigged, and nobody seems to notice, nobody seems to care. Good honest hard-working people -- white collar, blue collar, it doesn’t matter what color shirt you have on -- good honest hard-working people continue -- these are people of modest means -- continue to elect these rich c*cksuckers who don’t give a f*ck about them. They don’t give a f*ck about you. They don’t give a f*ck about you. They don't care about you at all -- at all -- at all. And nobody seems to notice, nobody seems to care. That's what the owners count on; the fact that Americans will probably remain willfully ignorant of the big red, white and blue dick that's being jammed up their assholes everyday. Because the owners of this country know the truth: it's called the American Dream, because you have to be asleep to believe it.

Bar za probu ni ne treba vraćati origigi ležište, može ona varijanta gdje je baterija u plastici sa 2 žice,
obavezno treba ispravno detektirati gdje je + a gdje je -,
ako proradi samo se izolira i fiksira sa kvalitetnim izolirom.

Na drugoj fotki se vidi da rupe na mbo za CMOS ležište nisu iste što znači da se lako može utvrditi kao on stoji na PCB-u. Kap superljepila će to srediti, a kontakti se zaleme za njega.

Nekima treba objasniti da se baterija na ploči ne skida istim alatom kao pločice u kupaonici. Korijen riječi je isti pa se ljudi lako zbune.
Čudno mi je da se laptop ne pali bez CMOS baterije, ali to je Acer pa tko zna što su izmislili. To se relativno lako popravi, jedan trace je cijeli, njega se lako ostruže i zalemi žičica prema bateriji, a i ona via (rupica) se može dovoljno ostrugati za zalemiti žičicu za nju. Trace pokraj baterije izgleda malo ostrugan, ako je prekinut treba ga popraviti komadićem žice. Tko ima malo iskustva u lemljenju to je lagan popravak.
Što se power tipke tiče, ona je obično izdvojena od ostatka tipki na tipkovnici pa bi trebalo probati naći na koja dva kontakta na konektoru vodi i onda probati napraviti bypass, za test se može spajalicom ili pincetom premostiti ta dva kontakta koja vode do power tipke i vidjeti je li se laptop pali. Vjerojatno je problem u tome nego u CMOS bateriji.

Nedavno je jedan moj frend bio stručno rastavio svoj stari laptop. Bio je baš navalio da pogledamo to skupa, kada sam vidio na šta to liči pomogao sam mu iz sažaljenja Prekidam ja radove i kažem ajmo mi to staviti skupa, a ona pita misliš da će upaliti Skoro sam umro od smijeha. Bio je polomljen konektor od napajanja, isto je bila i power tipka u nekom problem a sam laptop je bio polomljen na 10 mjesta. 5-6 vijaka je bilo provrćeno tako da se to sve skupa jedva držalo skupa. To niti McGyver ne spasi.

update: nije do baterije, a ni do tipke

kolega elektricar si dao truda, ali ne moze pronaci sto je na ploci otislo da ne trza niti malo

acer ima reset tipku ispod s kojom bi trebao uci u bios, ne reagira ni ona pa smo time eleminirali da ipak nije do power tipke

Ima san dosta slucajeva di bude loš DC jack, kao ima napone, svitli lampica, ima 3.3V na botunu za paljenje, al mrtav skroz, zato sam napisao, pročitao sam da pali lampicu od punjenja baterije. Onda provjeri taj vod od ispod baterije, pari poprilično oštećen.

Ta tipka ispod je samo za reset CMOS-a, ne za ulazak u BIOS ....

Laptop bi trebao upaliti bez te baterije, samo kaj nebi pamtio BIOS postavke ...

Ispitivačem ispitati da li na konektoru od power utičnice ima 19V (obično su crvene i crne žice, po 3 ili 4 komada) ....

Iza toga ispitivati kondenzatore prema masi sa zujalicom, jedna strana treba voditi, druga ne, ako vode obje nekaj ne štima s tim dijelom ....

Provjeriti i mosfete ....


P.S.: Mislim da gledate na totalno krivoj strani za pronalazak greške .... (što se slika tiče) ....
