|Computers are not warrantied against damage from external sources, although, in some cases, you can buy additional coverage when you buy the computer or within a short period of when you bought it that covers accidental damage that might cover that too.|
The most common types of external things that can damage your computer are power spikes or surges, lightning strikes near your location or lightning strikes on the AC power grid near you, and less commonly, static electricity discharges.
Your computer was probably exposed to something that damaged it
- you probably had at least the notebook's AC to DC power adapter plugged in; it could have entered via that
- if one or more cables connect your computer to the internet with no wireless connection in the chain, it could have entered via that
- if you had anything else that was plugged into the computer that uses a power adapter that plugs into AC power, it could have entered via that
- if where you had the computer has synthetic carpet and the relative humidity in that location is low, it could have been damaged from a static electricity discharge from that
If all devices that plug into AC that plug into your computer, whether directly or via an AC to DC adapter, and if applicable, a cable that connects you directly or indirectly through cables to the internet, are not plugged into a device that protects them against power spikes and surges, a power failure event or a glitch in the AC power being supplied to whatever you have plugged into AC that causes a power spike or surge can damage the computer and/or anything connected to it. A lightning strike can damage things even if you do have everything plugged into such a protection device. These protection devices often have a warranty you can make a claim on if whatever is plugged into it is damaged by some power spike or surge or lightning strike event, but in that case everything that plugsinto thecomputer must have been plugged into something that protects it from such, if there is more than one they often have to be made by the same manufacturer, and you often have to send whatever has been damaged at your own shipping expense to some place, or have it examined by someone local they approve of, and it may be weeks or months before you get any compensation.
The only thing you can do now is have that service center, or another local laptop repair place that is approved of by Acer to work on their products, examine the notebook to see if they can determine what the problem is and how much it would cost to fix that/those problems, and you make a decision from whatever they determine. They may charge a standard flat fee to make an estimate, or charge you according to how long it takes - ask them how much for an estimate before they actually do it.
If it's any consulation, usually when a computer is damaged by something external to it, in most cases only one or some things are damaged - e.g. the hard drive, the ram, and the cpu, are often still okay and can be used again no problem.
If you need to retrieve personal data on the hard drive you do not want to lose, if there's nothing wrong with it, that can easily be done by connecting it to a desktop computer with an inexpensive adapter.
By the way, when you unplug a USB cable, or a corded USB mouse or keyboard or whatever, DO NOT PULL ON THE CORD - pull on the connector on the end of the cord. It is easy to damage wires inside the cable if you pull on the cord, and that alone, in rare cases, could damage the USB circuits or something else on the computer. If in doubt, try replacing the USB cable, or try another corded whatever it is.
