[NIC08]

Tell me, the laptop was broken and for two and a half years just lay there, was not used at all. I recently decided to fix it, but the battery is no longer alive, it doesn’t get power, when I turn it on, the icon is “connected, 0%, charging”, after a few minutes, charging stops. It seems like overdischarge, is there any way to revive it somehow, or should I look for a new one? I worked only a year before the breakdown

It looks like overdischarge

On the contrary. Discharged to zero, the controller is locked.
Unlock it vryat whether you can. Look for a new one. Alas.

kind people, help, I bought a brand new laptop a week ago, yesterday I checked the battery wear in AIDA64 showed 0%, today 45%, did 2 cycles of recharging nothing helped, I think it's in the controller, how can I still calibrate it?

[peligroso]

iNDrod,marriage. Drag back.

[Delconte]

peligrosowhy so confidently say the controller crashes (maybe)

Posted on 1/6/2019, 12:40:

peligroso, it holds 0% for 2 hours, calibration did not help

[peligroso]

iNDrod,if you want hemorrhoids for your own money during the warranty period, then for God's sake. That was just advice. It can be safely ignored and the struggle continues.

[Delconte]

peligroso, there is no guarantee already)

[peligroso]

iNDrod,proceeded from your words

INDrod @ 01/05/19, 21:41

a week ago I bought a brand new laptop

[Delconte]

peligroso, okay, are there any ways to fix this bug?

[peligroso]

iNDrod,using a standard battery calibration utility, for example (if there is one for your beech).

There was a problem: the laptop turns on only when the battery is completely discharged and the charger is connected, if you charge the battery and then turn off the computer, the laptop does not turn on and the hard disk drive indicator does not light, but the laptop is noisy (the cooler is working). Please tell me what could be the problem here? Is the battery dead? or is there a problem in the hard drive? : scratch_one-s_head:

[= Duke =]

After buying a used laptop, Aida showed 77% battery wear. In a week or two - 71%. At the moment I use it for about 2 months. Yesterday wear - 60%. What does it mean?

[Faust-RSI]

The power supply is dead. Almost in stock. Roughly, the old unit is 4 A, on the battery and the laptop itself, 4 A is also registered, and the new unit has 3 A. Connected - everything works and charges. Both there and there Output 19V.

What is fraught ???

Acer Aspire V3-571G 2012th year, if it is important.

Faust-RSI,basically nothing. The battery will charge a little longer and bask more than the old one.

[Faust-RSI]

Well longer. this is understandable, not scary.
If it warms more - then the "wear" will increase?
In the next topic they write: "It is fraught with repeated combustion of the power supply from excessive load.
Its power should be enough to simultaneously charge and power the laptop.
One thing is easy to pull and this PSU. For example, charge a turned off laptop or power a laptop with a fully charged battery.
But if you charge an empty battery and at the same time run something heavy on the laptop, you can finish off this power supply. "

[peligroso]

Faust-RSI,depends on the quality of the PSU. I agree that with a huge load on a percent, the battery will not charge, but this is difficult to achieve, IMHO.
From my own experience I will say that I feed 7A units (Panasonic toughbook) with 5A charges and, sometimes, lower if there are no suitable ones at hand, but branded. Warm up, but normal. But the Chinese noname from such twists burned and melted, but it went about a year. The difference in 1A is not very large to get crit.

Well this is not a no-name. Another company, but also "native" to Acer. I didn’t meet the blocks with the Acer logo; they are equipped with at least three different companies. The old one was one, the new one - another, but this other in kits with Acer'ami goes ...
And so the old laptop, what kind of load does it have, the Internet, YouTube basically ... Although I noticed that while I changed the security settings for the hard partition (removed full control for a group of users), the battery did not gain a percent .. .

Comrades. Help me please.
Laptop: xiaomi notbook pro 15.4
OS: a dozen broken.
The laptop is three weeks old.
The trouble began with charging. Under load (for example, when WOW is turned on), the laptop stops charging, and the charge indicator starts blinking. Accordingly, with the brightness of the screen, epilepsy begins. The battery is discharged or charged - it does not matter. I turn off the game - charging starts in normal mode. There is no other power supply, of course. Infa did not find about this. How and what to test?

[peligroso]

bananik,Well, offhand, run the AIDA64 stress test and see the approximate consumption, and then compare with what is written on the power supply.

[cyxapeek]

Hello forum users. I was looking for my problem in the forum but because in a hurry I can’t find my problem. And this is it. Asus k53sm laptop does not see the laptop power supply and does not turn on without a battery. I tried everything that they advise on the Internet. When I remove the driver, the battery icon disappears. When I disconnect the battery with the battery and adapter turned on. The laptop works, but it seems to be inhibited. Any advice you need
