Wiki con Collaborazione Studenti
Un fantastico team di studenti del nostro programma educativo ha realizzato questo wiki.
The computer turns on, however shuts off shortly after.
Missing Critical OS Files
Critical files from Windows or another installed operating system may be missing. To troubleshoot, find an operating system that can run off of a CD like Ubuntu and see if the computer can boot off of that. If the laptop boots properly in the CD operating system, you will have to repair or re-install your main operating system.
If the computer does not detect enough RAM on start-up, it will not boot. Perhaps a RAM module became loose and just needs to be re-seated. To check, remove the RAM from the computer and re-install it in the same slots. Do not touch the gold pieces towards the bottom of the module.
Another problem could be a defective RAM module. Again, if the computer does not detect enough RAM, it will not boot. If you have re-seated all the RAM modules and the computer still does not boot, try replacing the RAM modules one by one with a working one.
If the previous steps have not remedied the issue, it is possible your motherboard is dead. This could result from a handful of different possibilities. If you have a bad motherboard, you have to replace it.
Not Powering On
The computer does not turn on.
If the battery has not been charged recently, it may be necessary to charge it.
If you attempted to charge the battery and the computer still does not power on, remove the battery, but leave the DC jack plugged in. If the computer powers on, you have a bad battery and the battery needs to be replaced.
It is also possible that the battery was not charging because the power adapter is bad. Try using a different adapter to see if the replacement charges the battery.
Replace DC Jack
A common problem with the MS2285 seems to be a faulty DC jack. Here is a link to a guide on how to replace the DC jack.
Not Registering Keystrokes
When typing, some or all of your keystrokes do not register.
If only some keys do not register, it is likely that your keyboard needs to be cleaned as small debris can impede key cap movement. Try using compressed air or a small brush to clean around the key caps.
If some of the keys still do not register, it may be necessary to remove some key caps in order to clean under them.
If all of the keys do not work, or after cleaning, some keys still do not work, it may be necessary to replace the keyboard.
Unusually slow when running multiple processes
Computer takes a long time to open/run programs
Not enough RAM
In order to determine how much RAM your computer is currently using while experiencing this issue do the following: Press CTRL + ALT + Delete --> click on "Start task manager" --> Click on the "Performance" tab --> Look at the Status of the "Memory" graph. This will tell you the amount of RAM currently being used and will show a visual representation of that number out of the total RAM on your computer.
Bad RAM Module
It is possible that you have a bad RAM module which is limiting your memory. If this is the case, replace the module.
Cannot Read or Write to Compact Discs (CD)
If a CD is inserted, the computer does not recognize the CD
It is possible that when the CD was written, there was an error which made the CD unreadable. Also, the disc could be scratched. To test, try some other discs to see if the computer recognizes them.
Faulty CD Drive
If other CDs do not work, the drive needs to be replaced.
