hay yew First off Welcome to iFixit. I noticed that you joined yesterday. Great. Now let's slow down. The purpose of this forum is to help other people with the repair of their devices. Nobody on here knows everything but everybody knows something. Hence repair is a team effort and as time progresses you will recognize that we have some real specialists on here like @imicrosoldering These specialists are not self promoters, they have proven that they know what they are talking about over and over.

What we do not tolerate on here is, profanity of course but also bullying, flaming, shaming or outright harassment. To keep this all nice and clean, you have a few community moderators that are active on this board and will let people know when they get out of line. It does happen and can most often be reigned in without problems.

The other thing you want to be aware of, is that we do not downvote an answer because we just do not like it, nor do we mark Answers, Questions or Comments as Remove as Spam/Offensive just because we do not like it. If it is spam or offensive it will be removed by those users that vote.

As a ground rule, remember to be nice, be kind and if there are days you might feel you lost your temper or got a bit caustic, be apologetic. But above all, treat those around you with the respect that they deserve and that they have earned. Here are the Community Guidelines we need to adhere to Community Guidelines

If you feel that somebody made a mistake or things could be handled differently, you can always involve the community moderators for clarification.

@mayer @jayeff @danj @oldturkey03 are the active moderators. There are more great moderators but they are not as active on this part of the forum. For issues that are not necessarily pertaining to Answers, you can always visit https://meta.ifixit.com/?pk_vid=145bf855... where the Community Manager and a lot of the great iFixit staff hang out.

Anyhow, welcome to iFixit.

If your phone wasn’t shutting down at 50% with the old battery but is with the new one than it could be that the battery you purchased is faulty. But first I would check that the battery connector is seated properly. There is also some components on the logic board around the battery connector that if nudged can cause problems with the battery data but this usually results in boot looping and no battery data. I would return the battery for a replacement one.

@uchetil I can solder, the thing is I'm not sure what exact chip I need to re-solder. I remember this video shows where to apply pressure when powering on. Also I remember once getting it to stay on longer than 10 seconds only turning off when I manually shut it off so I could figure out which one I held down. https://www.youtube.com/watch?v=ILLvioWt...

You can replace your charger to solve the issue because I think the charger does not provide the right vote to the laptop, so you can replace it. Downloadtimecalculator

ViolentTubeGaming How did you clean it? Post some good picture of how this all looks and it'll help us to identify the " I even replaced the white thing" (wonder what you replaced there) and "the green thing"

Mine is a Dell pentiam 4 , it's been doing this for months and it doesn't show on the screen

First your system is so new it shouldn't need any alteration of the thermal conduction system.

The design of the MacBook Pro systems won't allow the use of this product without making major modifications of the heat sink, which in turn will make it less effective than the current design and will void your warranty. Two steps back one step forward ;-{

Basic cleaning should resolve overheating issues (dust buildup on the fan and fins). If this was an older system then it might make sense to refresh the thermal paste to the Arctic product which is what we use when needed.

I would first do some diagnostics on why your system it is overheating if that is the case. Get a good temp & fan monitoring app like: Temperature Gauge Pro and use Active Monitor to see what app or process is consuming the CPU's cycles.

More often than not, I find bad apps or a stuck process is the root issue of many heat issues, with hardware I often find the wrong HD or SSD was used in an upgrade (which shouldn't be an issue here).
