I get a double beep on startup


Ram Memory problem.

1) Remove ALL power.
Remove the AC adapter (Charger), and Battery.

2) Suggest lay a soft cloth on the table you are working on.
Laptop closed, turn it over, lay it upside down on the table.

3) Open the Memory Compartment, and remove all Ram Memory modules. ('Stick')

4) Clean the gold plated contact pins with a pencil eraser.

Basic example of a SO-DIMM ram memory module, as used in a laptop,

http://en.wikipedia.org/wiki/File:1GB_DDR2_SO-DIMM.png

Everywhere on the Ram Memory module, Except the gold plated contact pins on the bottom, is the BODY.

The Body is coated with a see-through protective plastic.
Handle the Ram Memory module by the Body.
Refrain from touching the gold plated contact pins.

Use a pencil eraser.
If you are using an eraser on the end of a pencil, and not a solid eraser, refrain from letting the metal band of the pencil, touch the gold plated contact pins.

Rub up, and down on EACH contact pin. BOTH sides.
Doesn't take much pressure, nor a whole lot of rubbing to clean those contact pins.
In fact when you are done, they may not be shiny, and bright.

You may feel you have done nothing at all.
I assure you that you have.
Doesn't take much 'corrosion' to make a bad contact surface.

Use air to remove the eraser dust. If you have a can of compressed air for computers, use it. If not air pressure from your mouth will be sufficient.
(Also if you have compressed air, bl-ow the ram memory slots out also)

If using compressed air, allow a few minutes for any moisture that may have developed from the air, to dry.

Reinstall all ram memory modules.
Reinstall the Memory Compartment Panel.
Plug the Battery back in. Plug the AC adapter in, then plug the AC adapter into power.
WAIT 1 minute, turn the laptop on.

My laptop is stuck. On the screen, it displays;


OMG!

!O_O!

A) Remove ALL Power. Remove the AC adapter (Charger), and Battery.

Laptop closed, work on a table.
(Not a bed, couch, or directly on a carpet floor. She said what? Oh,....well put a clean, static free towel on the table, to prevent scratching it, and the laptop)

Turn the laptop over. Remove the screw/s that hold the Memory Compartment Panel, on.

Remove all Ram Memory module/s. ('Stick')
Ease the spring clips out at the top. When both spring clips are brought out, the ram memory module will pop up a little.

Remove the ram memory module AT THE SAME ANGLE it is in.

If you bring it straight up, you will damage the gold plated contact pins, on the ram memory module, and also the contact pins in the ram memory slot.

Handle the ram memory module by the BODY.
The Body is everywhere on the ram memory module, except the gold plated contact pin at the bottom.
The Body is coated with a see-through protective plastic.

http://en.wikipedia.org/wiki/File:1GB_DDR2_SO-DIMM.png

Note the Side Notches. This is where the spring clip's 'bumps', go into.
Note the bottom Locating Notch. It is actually off to one side.
The Locating Notch lines up with a Locating lug, in the bottom of the ram memory slot.
Means it can ONLY be installed in one direction.

Use a pencil eraser, and clean the gold plated contact pins.
If using an eraser on the end of a pencil, and not a solid eraser, refrain from letting the metal band at the end of the pencil, contact those gold plated contact pins.

Gently rub up, and down on EACH contact pin. BOTH sides. Doesn't take much to remove the 'corrosion'. Don't run too hard.
They won't be bright, and shiny when you are done, but I assure you that you have cleaned them.

(Doesn't take much 'corrosion' to make a bad contact. I use 'corrosion' in marks, because Gold isn't supposed to corrode)

Use air to remove the eraser dust. If you have a can of compressed air for computers available, use it. If not air pressure from your mouth will be sufficient.

Reinstall all ram memory modules. Replace the Memory Compartment Panel, then turn the laptop over.
Reinstall the Battery, and AC adapter. Then plug the AC adapter into power.
WAIT 1 minute, turn the laptop on.

Toshiba Satellite L655D s5050 when turn on power comes up charging light comes up disc drive works but nothing on screen and the vga port didnt work as well


Nothing on internal monitor screen, and nothing on external VGA monitor?

You have a bad graphics chipset. This = replace motherboard.

Before you rush out to buy a motherboard, let's review on how to properly connect a VGA monitor to that Toshiba Satellite L655D-s5050;

1) Laptop OFF, monitor OFF, connect the VGA monitor to the RGB port on the side of the laptop.

2) By DEFAULT, the display should show on the external VGA monitor.

DOES NOT mean it will.

No display on external VGA monitor?
Press, and hold down on the Fn key, tap ONCE on the F5 key.
(O-N-C-E. NOT repeatedly!)

Still no?
Hold the Fn key down again, and tap once more on the F5 key.

Still no?


Hold the Power On button down until the laptop turns off.
Remove the VGA cable, and all external cables/devices.

Close the laptop, turn it over on the table in front of you.
(I recommend a soft, static free cloth on the table, to prevent scratching the table, and laptop)

Remove ALL power. Remove the AC adapter (Charger), and Battery.

Remove the Memory Compartment Cover.
(Middle of laptop on bottom. Rectangular cover with three Philips head screws)

Make SURE your body is free from Static, and remove all ram memory modules. (Slot A, and Slot B, IF, there are two ram memory modules)

Handle the ram memory module by the BODY. The body is everywhere, but the gold plated contact pins on the bottom.
The body is coated with a see-through protective plastic.
Refrain from touching the gold plated contact pins.

Clean EACH gold plated contact pin with a pencil eraser.
BOTH sides.
If using a pencil eraser on the end of a pencil, and not a solid eraser, refrain from letting the metal band contact the gold plated contact pins.

Just rub up, and down on each pin.
When finished use air to remove the eraser dust. You can use a can of compressed air for computers if available, or air pressure from your mouth will be sufficient.

Reinstall just one ram memory module, (If you have two), in Slot A.
Make SURE it is in Slot A. The Processor reads Slot A first. If no ram memory module is in Slot A, the laptop will not work.

Put the Memory Compartment Cover back on.
Reinstall the Battery. Turn the laptop over, and open it back up.
Plug the AC adapter (Charger) in.

WAIT 1 minute, turn the laptop on. Still no?
Turn the laptop off, and attach the external VGA monitor again.
Try it. (Don't forget you may have to use the Display Toggle-Over key)

Still no?
I suggest the graphics chipset is bad. Motherboard replacement.

My light blinks three times and nothing happens?


1) I would like you to remove ALL power to the Notebook PC. Remove the AC adapter (Charger), and Battery.

2) Place a towel on the table you'll be working on. Place the laptop upside down on the towel. (Bottom facing up. Towel helps to protect table surface, and laptop finish )

3) Looking at the bottom of the laptop, with the Battery Compartment facing away from you, the Memory Module Compartment access cover, is in the middle. (Rectangular cover with a vent in it. The larger Harddrive Bay access cover is below it )

Loosen the two Philips head screws in the cover. Lift the cover on the same side as the screws. Lift the cover at approximately a 45 degree angle, when removing. There are small plastic tabs formed out of the cover, on the opposite side of the screws. These may be easily broken off, if the cover is lifted straight up.

The spring-like retaining clips hold the ram memory module in place.
One on each end. These are gently spread to release the ram memory module.
When released the ram memory module will pop-up slightly.

The ram memory module should be removed, at NO more than a 45 degree angle.

Bringing the ram memory module straight up when removing, will bend the contact pins in the ram memory slot, and damage the gold plated contact pins on the ram memory module.

The gold plated contact pins develop a type of 'corrosion', after time.
This leads to a poor contact with the ram memory module to the ram memory slot.

Advise use a pencil eraser to clean the gold plated contact pins.

http://en.wikipedia.org/wiki/File:1GB_DDR2_SO-DIMM.png

If using an eraser on the end of a pencil, and not a solid eraser, refrain from letting the metal band touch the contact pins.

Handle the ram memory module by the Body.
The Body is all of the ram memory module, Except the contact pins.

The Body is coated with a see-through protective plastic. Helps shield the ram memory module from Static. (Electricity)

The bottom of the ram memory module is the contact pins.
Start at the top of each contact pin with the eraser, and stroke down.
Do this for All contact pins. Both sides of the ram module.

Doesn't take much rubbing to clean the contact pin. When finished use air to remove the eraser dust. You can use a can of compressed air for computers, if available, or air pressure from your mouth will be sufficient.

Reinstall the ram memory module/s. Reinstall the Memory Module
Compartment cover. Reinstall the Battery. Turn the laptop over on a Hard surface, (No towel), and attach the AC adapter. Plug AC adapter into power.

Wait 1 minute. Turn the laptop on.

Still no joy? Post back in a Comment.

When i try to turn on nothing happens front light just flashes white then blue nothing on screen


It sounds like you may have either a defective video card or RAM. To test the RAM, open up the RAM bay on the bottom of the laptop and remove one stick. If the computer still isn't starting, swap the stick that you took out with the one that is still inside. if that didn't help then you should take it in to the manufacturer for repairs. NOTE ABOUT HANDLING RAM: RAM is very sensitive to static electricity so be very careful not to touch the gold leads on the bottom. Good luck!

My cpu is running but i don't hear any sound beeping.


Try to remove the RAM and video card, clean the gold plated pins with dry cloth and re-seat them. Then turn the computer on.

If you get the same problem, most likely, you've got a bad RAM or video card.

Thank you!

Compaq Presario v5000 won't turn on


If the laptop posts: (power on self test) and you see stuff on the screen, no matter how short ,do the following:
if you have a bootable anti virus disc use it to check for any viruses , if not
try a recovery disc,
both will try to access the hard drive.
if they do not work,(nothing has changed) nothing comes on the screen.
laptop does not post:
remove the screw(s) holding the cover plate where the ram lives
remove the memory sticks, clean the gold edges with a pencil eraser both sides and re-insert them, (not an ink eraser as it will do damage)
swap them around if you have more than one,
if you only have one, borrow one from a friend or try the ram in your friends laptop ,if that's possible, or take the ram to your local pc shop and ask them to check it for you (they may or may not do that for you)
if you can establish that the ram is ok, and anti virus and recovery disc's do not work,then it is most likely, the motherboard has failed .
good luck with that and let me know how you get on.
