Easiest way to know problem. If laptop has a light for battery, connect the charger and see if light turns on. If it flashes orange then indication means problem is the battery itself not the charger.

Some repair shops blame it is charger or a component on the motherboard and charges high price to scam. But real cause is just the battery itself that needs to be replaced and nothing else.

This is why going to a 3rd party repair place can be sketchy some times, some are unskilled have no idea what they are doing. While others knows what they are doing and do not scam customers.

Never had todo that, had dedi server with them before and never needed them to unblock any ports. So I don’t think you do need to, unless they changed.

Well no port should be blocked on default. Not even 25

Like other said to get blocked for some stuff is either because you used server for email spamming so they choose to block it.

When setting up a email server you must make sure no one else can compromise it and use it for sending out spam mails.
