Black or Blank screen fix?

Often I see people say they turn on, lights are on but NO screen. The fix maybe to REMOVE and RE-SEAT the RAM module. Usually it is located under a flap under the Laptop. Remove the flap, take out the SIMM and then replace it. Often this will restore things back to normal. But NOT always.

My Dell XPS 420 will not turn on. Power light shows a steady blue color. No diagnostic lights show up.


The RAM maybe faulty.
Try resetting the RAM modules to make sure it is seated correctly in the memory slot.
If the computer still does not boot up then the RAM maybe faulty. Remove the RAM module/s and take them to your friendly computer repair shop and get them tested. If faulty then replace the RAM.

two light is blinking and the computer's screen stay black


What type and model of PC? I sometimes see this on Dells when the RAM is loose. If you turn off and unplug the PC, remove the RAM and then re-seat it may fix it. If it doesn't it's time to unplug anything that's attached to your motherboard (other than the power supply) and connect one thing at time until the issue returns. Once the issue returns then the last thing you plugged in is the culprit. For issues like this it's usually the RAM or the power supply... or at least usually ;)

turn signals will not work on 1991 electra glide when you apply the front brake there is a clicking noise from a module under the seat


The clicking you hear may be an add-on module that makes both rear turn signals into brake lights. Remove the seat, locate the clicking module and remove it, it should be about 2.5" long and about 2" wide and 1/2" thick, then put the plugs back together w/o the module and try the blinkers. One on of the module is female the other male to help locate it, but it's one of the few connectors that are quite big under the seat. Harley sells these or they did, as well as a couple aftermarket makers. I have one on my FLHT.

Where is the memory ram located in the compaq n610c laptop?


Notebook, (Laptop), open, look at the panel to the Left of the Touchpad. This is the Memory Compartment Cover.

To open the cover you must remove the Keyboard.

To remove the Keyboard:
1.Remove the AC adapter, (Charger), if plugged in. Remove the battery. There must be NO electrical source!

2.Work on a table.
I have to state this because of Static issues.
Static will fry out delicate computer components.
You may not see it or feel it. Working directly on a carpet floor, a bed, or a couch, is a No-No. These are High areas of Static!

3.Turn the laptop over on it's top. In the Middle of the back is a single screw. (Philips head screw. Size TM2.5 x 7.0)
Remove it.

4.Turn the laptop back over to it's normal position, front facing you. Open the laptop. Lay the LCD screen all the way down, Away from you. I advise putting a lint free soft cloth over the screen, to help prevent accidental damage.

Release the locking tabs that hold the Keyboard in.

Slide the four tabs at the top of the Keyboard, Forward. (Slide them towards you. These tabs are located as follows;
A.To the Left of the F1 key
B.To the Left of the F5 key
C.To the Left of the F9 key
D.To the Right of the F12 key

Lift the Top of the Keyboard up, (Top of keyboard faces LCD screen), swing it up and Forward, (Towards the LCD screen), until it rests on the LCD screen.

Now you can lift the Memory Expansion Compartment Cover. (Lift the Left side, swing the cover forward) Remove the cover, lay it aside.

To remove a Ram Memory Module: (Ram stick)
Spread the Retaining Tabs, that hold the Ram Memory Module in place.

(The silvery metal clips, that you see on each side of the ram stick. You'll note that they have rounded protrusions on them, or 'Bumps'. These bumps go into a notch on the ram stick. The Retaining Tabs only need to be spread far enough, so that the bump is clear of the notch)

CAUTION!
The ram modules come out at a 45 DEGREE ANGLE. They DO NOT come straight up.

If you lift them straight up you will bend the tiny pins on the ram module, (Stick), and render the ram module useless! You can also damage the laptop's ram slot!

To install a ram module:
Angle the ram module at a 45 degree angle, line it up with the slot. BE AWARE that each ram module has a Locating Notch on the bottom of it.

The Locating Notch lines up with a Locating Lug in the bottom of the ram slot.

It's a bit of a balancing act your first time, but you use your forefingers and thumbs to hold the ram module, and also spread the Retaining Clips, while inserting the ram module.

You should hear a satisfying click, click, as each retaining clip 'Bump', clicks into the notch on the side of the ram module.

acer travelmate 292elcI problem starting


Hi, sorry to hear you are having problems. When this happens it usually suggests that the CPU/system board has failed. If the laptop is still under warranty I would suggest taking it back because this is something that will be covered and they should be able to fix it or replace the laptop itself. If not you may have to pay to have the system board/CPU replaced. Good luck and hope this helps. Si :)
