Abulging tablet casingis a classic sign of aswollen lithium-ion battery, often caused by age, overheating, or overcharging. This is adangerous condition, as swollen batteries can rupture or catch fire. It also explains why the tablet only works when plugged in the battery is no longer holding a charge.

Option A:Power supply issues wouldn’t cause physical bulging.

Option B:A bad charge port wouldn’t cause screen damage or physical distortion.

Option D:A broken screen could cause display issues, but not the bulging chassis.

The technician should reinstall the printer driver software. Continuous pages of random characters usually indicate that the printer is receiving data in an unsupported or incorrectly interpreted printer language. This commonly occurs when the wrong driver is installed, the driver has become corrupted, or a driver configured for a different printer model sends incompatible PCL, PostScript, or proprietary commands. Reinstalling the correct manufacturer-supported driver restores proper translation between the operating system and printer. DPI settings control print resolution and image detail but do not cause raw characters or command data to print continuously. A toner problem would produce faded, blank, uneven, or smudged output rather than correctly formed random symbols. Updating firmware might help with compatibility in some cases, but the established first corrective action for garbled character output is to remove and reinstall the appropriate printer driver.

A USB-C-to-HDMI adapter is the most appropriate choice for a modern laptop that lacks built-in VGA and HDMI ports. Many current laptops provide display output through a USB-C port that supports DisplayPort Alternate Mode or Thunderbolt. A compatible adapter can convert that digital signal to HDMI, which carries both high-definition video and audio to the projector through one connection. MicroUSB is primarily an older mobile-device charging and data connector and does not normally provide native laptop display output. DisplayPort-to-VGA would require the laptop to have a full-size or Mini DisplayPort connection, which is not stated. DVI-to-HDMI would similarly require a DVI output on the laptop, and standard DVI generally does not carry audio. Provided the laptop’s USB-C port supports video output, USB-C to HDMI is the most practical and capable adapter.

A public IP address is required so internet-based clients can route traffic to the organization’s network. Public addresses are globally routable and are normally assigned by an internet service provider. The web server may itself use a private address, but the organization’s internet-facing router must have a public address and use port forwarding or static NAT to direct HTTP or HTTPS requests to the internal server. Merely having an IPv4 or IPv6 address is insufficient because either protocol can use addresses that are not externally routable. A dynamic address can be public, but it may change and is therefore unsuitable for reliable server hosting unless dynamic DNS is configured. The defining requirement is public reachability, not whether the address is IPv4, IPv6, static, or dynamic. Therefore, a public IP address is the best answer.
