Satellite M305 M305D display image flickers disappears

I have seen a few Toshiba Satellite M305 and M305D laptops with exactly the same display problem. When you move the display panel, the image on the screen flickers, some random horizontal lines appear in random places or the image disappears at all. As soon as you stop moving the display, the image ether turns back to normal or the display continue to remain black.

posted in: 3. Compaq & HP | 27

In this guide I explain how to take apart the display panel and replace the inverter board in HP Compaq 8510p and 8510w notebooks.

The inverter board located inside the display panel below the LCD panel.

The inverter works as a power supply for the backlight lamp inside the LCD.

When inverter fails, the LCD goes dark. The image is still on the screen but you can barely see it.

OK, let’s start taking it apart.

STEP 1.

You can remove these covers with a sharp object.

Laptop does not start. Is it bad power jack or motherboard?

posted in: Miscellaneous Tips | 446

Let’s say your laptop does not start at all. You plug in the power adapter and press on the power button, but the computer will not react. It’s dead and the power or battery charge LED will not light up.

What could be wrong? Is it bad power jack or the motherboard is dead?

Laptop top cover removed

By the way, the power jack (DC-IN jack) is the power socket on the side or back of your computer where you plug the AC/DC power adapter.

I’ll explain how to perform basic troubleshooting and find out what is wrong. This is only for experienced people, who know how to disassemble laptops.

Problems with power socket in Toshiba Satellite L305 L355

posted in: 8. Toshiba | 60

Lately I’ve been seeing exactly the same problem with the power socket in some newer Toshiba Satellite L305/L305D and Satellite L355/L355D laptops.

I don’t know if it’s a poor design or people just not careful enough with their computers, but the power socket in these models breaks very often.

On the picture below you can see a good working power socket. The power jack is seated correctly. It’s tight and will not move when you plug in the adapter.

On the next picture you see a broken socket. There is a gap between the power jack and bottom case and when you plug the AC adapter inside the jack it feels very loose.

In some cases, the power jack separates from the case and you cannot plug in the power adapter at all.

How to upgrade RAM in Toshiba Satellite A45

posted in: 8. Toshiba | 33

In this guide I explain how to upgrade RAM (memory) in a Toshiba Satellite A45 laptop.

If you search for memory slots on the bottom of the laptop, you will not find any because both slots are hidden under the keyboard.

In order to access both RAM slots you’ll have to remove the keyboard. Don’t worry, it will take about 5 minutes even for inexperienced users.

Before you start,  turn off the computer, unplug the power adapter and remove the battery and of course, proceed at your own risk. :)

STEP 1.

Insert a small flat head screwdriver under the keyboard bezel and lift it up.

How to take apart Gateway NX570X

Gateway NX570X laptop

In the following guide I take apart a Gateway NX570X laptop.

I think my disassembly instructions will work for other Gateway NX570 models too.

In my case the battery started charging intermittently with the AC adapter connected.

In order to charge it I have to adjust the AC adapter plug inside the power socket on the back of the laptop. Apparently, there is a problem with the power socket (DC jack) and it has to be replaced or resoldered.

I’ll be removing the system board so I can access and repair the jack.
