How do you obtain mac address of HP Laserjet P2055dn?
Usually you don't need the MAC address directly - except perhaps to improve the documentation in a large network.
If you know a device's IP address, you can do a pingcommand; before and after, compare the ARP cache - the one that shows assignments of IP addresses to MAC addresses. In Windows, the steps would be more or less like this:
- arp -d * (this will delete the ARP cache)
- arp -a (this will show the ARP cache)
- ping ... (this will connect to the IP address you specify)
- arp -a (show the ARP cache again. Compare with the previous one.)

How much does it cost to repair an Apple laptop?

hope this helped :)
CPU's are usually directly attached to the motherboard or they are in a slot that is under a fan. If the CPU is broken, it is very hard to fix because they are small and are not made to be user serviceable. The best thing to do if your CPU goes out is to just go to the store and get a new one that is the same. CPU's are generally expensive so make sure that it wouldn't be cheaper to just go out and get a new computer. It also may be a good idea to just bring your computer to a repair shop and have them replace the CPU so you don't mess something else up too.
How is preventive maintenance conducted?
Preventive maintenance is a schedule of planned maintenance actions aimed at the prevention of breakdowns and failures. The primary goal of preventive maintenance is to prevent the failure of equipment before it actually occurs. It is designed to preserve and enhance equipment reliability by replacing worn components before they actually fail. Preventive maintenance activities include equipment checks, partial or complete overhauls at specified periods, oil changes, lubrication and so on. In addition, workers can record equipment deterioration so they know to replace or repair worn parts before they cause system failure. Recent technological advances in tools for inspection and diagnosis have enabled even more accurate and effective equipment maintenance. The ideal preventive maintenance program would prevent all equipment failure before it occurs.
Maybe you are talking about "boot.ini".
This is an example of a boot.ini file: [boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(2)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Microsoft Windows XP Professional" /fastdetect
Where menu options are stored.
For example if you have two operating systems installed in your hard disk. The NTLDR shows the boot menu where you
have to select which operating system you want to start. The boot menu is the boot.ini.

What types of files might you not want to delete during disk cleanup and why?
Here are some of the files you may or may not want to delete depending on your situations.
1. Recycle bin - Sometimes you accidentally throw things away, so you might want to check it and make sure.
2. System logs - Normally, you can delete these, but if you have system problems you'd want to review them.
3. Service pack backups - You may need these if Windows updates causes unintended problems.
4. Thumbnails - There is no harm if you delete them, but it will take longer to view thumbnails in a folder.
5. Old personal files - Disk Cleanup doesn't have this option, but other utilities like Ccleaner will offer to remove any files you haven't used in a while. If you have a library of documents, music, sounds, videos, graphics, photos, etc., and it took years to build them, you likely don't want to lose those.
All computers have a processor, memory, and a mother board. Other components are added, usually by the manufacturer, to accommodate the ability of the computer hardware to run software, including the operating system, and other software to complete tasks, such as business, art, engineering and more tasks.
