Your installation medium may be corrupted. Try downloading Ubuntu again and burn it to disc or use Linux Live (Google it) to load it onto a USB drive to boot from. Once you do that try reinstalling it. Make sure you download the latest version, either 12.04 LTS or 13.10 (currently latest as of Nov 10th). A new version is released every 6 months and a new LTS is released every 2 years. Version number signifies the year (12 for 2012, 13 for 2013) and Month.
To adjust the brightness in your Acer Travelmate, press the [FN] key then press the left or right arrow directional keys which is usually on the lower right-hand side of the keyboard. You will identify the brightness and dim symbol/icon. I hope this is of help. Thank you.
Hi Friend,In this case I would recommend, to unplug the printer from the system and also turn off the printer. Waith for 10-15 seconds, and connect the printer to the power socket first wait for a while till it gets ready and then connect the printer to the system and then check if you are able to see the printer or not. Also, let me know when was the last time you were able to use the printer. If the above step fails - Probably its a driver issue so, you have to let me know the make and model# for the printer and I can give you the suitable drivers for the same.
Hi,Looks like an issue with either display or system is overheating. Please try the below steps.1. Shut down the computer2. Keep on tapping F8 key as us press the Power button to turn on the computer.3. Choose safe mode using the arrow keys on the keyboard and hit Enter Key4. Stay on the safe mode to see if the screen is going blank, if not5. A system restore should help to fix the issue. Let me know!Thanks!Anil.B.R

- rules
Only work inside the computer case
when the power has been switched off and disconnected. Never open the power
source.
Some of the below steps
recommend removing physical parts within the computer.
While in the computer it is
highly recommend that you be aware of ESD and its potential hazards
Remove the memory modules from their
slots.
Take the
opportunity to clean the slots on the motherboards and the memory module
connectors.
Use compressed air to blow dust away
and clean contacts with a soft cloth.
Do not use a metallic vacuum cleaner
if it touches any component it may create a short and cause damage to the
motherboard or other components.
Do not use
solvent that may attract dust and never poke things like cotton buds in to
slots. lightly rub an alcohol (Methylated
Spirits) on a cloth not to hard let the alcohol do the work on the copper gold
or silver tabs and r
Allow the pins to dry.
They will air dry in a matter of
minutes
If reseating the memory did not
resolve the issue try swapping the location of the memory.
If you have only one stick of
memory in the computer try moving it to another slot and then boot the
computer.
Check the memory module and memory
slot contacts.
They are either copper tin or gold.
The colour will tell you which they
are.
Mixing tin and gold can result in
corrosion that prevents proper contact.
Look for any sign of physical damage
to the memory module, memory slots or the motherboard.
Reseat the memory modules.
You should hear an audible click
when they are in place.
Do not use
too much force to reseat the memory module in to the slot this can cause damage
to the module, slot or motherboard.
Could even
be a virus or malware

Thermal compound is a sticky paste that is placed
directly onto the CPU.
http://www.hardwaresecrets.com/article/Thermal-Compound-Roundup-February-2012/1490
Allowing for a more direct heat transfer between
the CPU and HEAT SINK and preventing air gaps from forming between the CPU and
heat sink.
The hardware that you are trying to access is damaged
or failing.Capacitor
Capacitors, sometimes also called condensers, are
used to store energy in an electric field.
In the context of computing, capacitors are used to
block the direct current being circulated around the motherboard.
A typical capacitor should last up to 15 years, but
some computer manufacturers use substandard capacitors resulting in shorter
lifetimes.
Computer Problems
When a capacitor has gone bad on a computer you may
experience a large range of problems. The computer may have trouble booting up,
or it may shut down without notice after running for only a short period of
time.
The most common problems associated with faulty
capacitors are that they cause unexpected computer crashes and general
reliability issues ranging from read/write issues to distorted screen images.
Identifying a Bad Capacitor
To identify a bad capacitor you will need to open
your computer case and locate the capacitors on your motherboard.
A bad capacitor may exhibit swelling at the top or
the base of the capacitor or it may sit at an awkward angle with the
motherboard, so compare the various capacitors in your computer in terms of
size and placement.
Additionally, a bad capacitor may have a funny smell
or it may have a brownish residue leaking from the top or the base.
Prevention
Manufacturers claim that capacitors may go bad
because a computer is not receiving enough power from a power supply, because
of an overclocked processor or because a computer is operating in an
environment with too much heat or humidity.
However, some capacitors prematurely fail due to
faulty work on the part of the manufacturer.
If you have a bad capacitor be sure to do research as
to the lifespan of other products made by your manufacturer.

are faulty or incompatible.
Could be a problem with the Hard
Drive or the Hard drives PCB
http://www.onepcbsolution.com/
There is a connection problem such
as a bad cable
Test all power and data leads that attach to your hard drive SATA
the leads from your MOTHERBOARD TO THE
HARD DRIVE make sure they have a
secure dust free connections and are
not faulty.
Although it would be very rare for
the sata lead to be faulty.
Make sure all leads that are attached to your drives
dvd\cd have secure connections and are not faulty
Computers need power and data to travel through
every working device and continue its cycle and have an end so any faulty leads
will end up with a computer error.
download it again... you can find it on torrent sites, but youll need to download utorrent 1st to obtain it.i cant tell you the name of the site but it has something to do with pirates and bays....

hmn.. i would try it on another computer before tossing it out... i would also try to start up the pc with a cd on it and trying to boot from it just to see if windows is the cause of the problem. if it boots from the cd the it works.
