Did this last night.

The key to the whole case opening is the silver panel in back of the keyboard. It has clips on the sides and clips over the screen hinges, but the tricky clips are the two under the battery. Once you get this panel off, you can take out the two keyboard screws.

Take the keyboard off second so that you can get to the three ribbon cables under it before you get too far into the tear down.

Don't forget the three screws hiding inside the DVD slot (you have to remove the DVD to get to them).

Toshiba satelite L45-4687 bios password lost


You will need to open the Toshiba case, then find and remove the battery from the motherboard for a few minutes before replacing it. Some Toshiba laptops have a BIOS reset switch on the motherboard. In both cases you need to open the laptop case to solve your problem.

Laptop won't boot up


Here below are possible causes and troubleshooting steps of laptop that can't power on, hope it may help:
Possible causes:

1. Toshiba Satellite A215 adapter failure.
2. Power jack failure.
3. Motherboard failure.

Possible troubleshooting steps and repair solutions:
1. Test the AC adapter with a digital multimeter. It's possible that you have a failed AC adapter. If you don't have a multimeter, test your laptop with another known good AC adapter.

2.It's possible that power jack (socket where you plug the AC adapter) is broken. Remove the motherboard and take a closer look at the power jack. In some cases you can fix the jack by resoldering it on the motherboard. In other cases you have to replace the jack with a new one. Using a multimeter, test if the power goes to the motherboard through the jack.

3. If replacing the AC power adapter and jack on the motherboard doesn't help, most likely you have a bad motherboard. Replace the motherboard.

How do i safely remove the cable that attaches to the motherboard on my toshiba laptop


Toshiba satellite motherboard removal.

A motherboard is usually replaced for one of two reasons. You either replace a motherboard because it has gone bad, or you replace an older motherboard with a new or upgraded motherboard. In either case you will have to completely disassemble your laptop to even gain access to your motherboard. Fortunately, the Toshiba Satellite laptop can be completely disassembled even if you don't have a lot of technical knowledge.

Turn off the laptop, disconnect the power cable, remove the battery pack and disconnect any miscellaneous cables and peripheral devices. WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL. http://www.kitchentablecomputers.com/static.php - 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 Attach an antistatic wrist bracelet to prevent shock from static electricity. Static electricity can harm your computer's internal parts. Place the laptop face down, and remove the single Phillips-head screw attached to the hard drive cover. Remove the hard drive cover, then set it aside. Remove the single Phillips-head screw attached to the wireless card/memory cover. Remove the cover and set it aside. Slide the hard drive out of its compartment. This will disconnect the hard drive from the computer. Set the hard drive aside very carefully.

Remove all marked screws from the bottom casing of the laptop, and then place the laptop face up. Open the laptop as far as it will go. Use a small flathead screwdriver to pry up the keyboard bezel. The keyboard bezel is a small plastic strip sitting between the keyboard and the LCD display. Remove the two Phillips-head screws securing the keyboard in place.

I have a toshiba satellite r15-s822. I am trying to remove the bios password. I removed the rtc battery. Is there another cmos battery on the motherboard? What am i doing wrong?


To reset the BIOS read the information from this link.

In case of your Toshiba Satellite R15-S822 laptop the easiest method would be using software from Hiren's Boot CD as it's pretty hard to open it up and reach for the CMOS battery (which is on the motherboard) or the jumper.

Replace keyboard on Acer 4720Z


Hi..

I will provide you a solution this solution are very useful with you. You can do it with your self to follow this instructions. There are some image on how to replace the keyboard.

These instructions will help you to remove and replace keyboards on various laptops. I will not be able to cover all models but you’ll get the idea. Steps for removing and replacing the keyboard are similar for most laptops.
Warning!
- if your laptop is still covered by the manufacturer’s warranty, do not open the case or you can loose the warranty
- always remove the battery and unplug the AC adapter before you open the laptop case
- if you damage the keyboard connector on the motherboard you’ll have to replace the whole motherboard
- proceed on your own risk
Sony laptop
I took these pictures from a Sony Vaio PCG-K33 (model PCG-9S1L) notebook. Should be similar for some other Sony notebooks too.
sony-keyboard-1.jpg Insert a small flathead screwdriver under the keyboard bezel and carefully lift it up. Continue releasing plastic latches and removing the keyboard bezel with your fingers.
sony-keyboard-2.jpg
Be careful, on some models the bezel might be connected to the motherboard as it shown on the picture above. If you accidentally pulled the cable, connect it back. It is not necessary to disconnect the keyboard bezel from the motherboard in order to remove and replace the keyboard, just put it aside so you can access the keyboard screws.
sony-keyboard-3.jpg Remove three (or more) screws from the top of the keyboard. Carefully lift up the keyboard from the laptop case.
sony-keyboard-4.jpg The keyboard connects to the motherboard via a flat ribbon cable. Before you pull the cable from the connector, you’ll have to unlock the connector.
sony-keyboard-5.jpg The image above illustrates how to unlock the keyboard connector. Carefully move the connector lock 2-3 millimeters up and after that pull the keyboard cable. To install the keyboard, follow the above mentioned steps in the reverse order.
Toshiba laptop
The following pictures were taken from a Toshiba Satellite A135 laptop. The keyboard removal instructions will be almost the same for most modern Toshiba laptops.
toshiba-keyboard-1.jpg The keyboard bezel removal procedure is similar to the above mentioned Sony Vaio laptop. Lift it up with a small screwdriver and remove using fingers. On most Toshiba laptops the keyboard bezel doesn’t have any circuit board underneath, it’s just a piece of plastic and you don’t have to worry about cables.
toshiba-keyboard-2.jpg After the bezel is removed you get an access to the keyboard screws. Remove two (or more) screws. Release the plastic latch pointed with the red arrow and lift up the keyboard. Carefully put the keyboard aside so you can access the connector underneath the keyboard. Do not forget that the keyboard is still connected to the motherboard.
toshiba-keyboard-3.jpg Before you remove the keyboard, you’ll have to open the connector and release the flat ribbon cable.
toshiba-keyboard-4.jpg Here’s a closeup picture of the keyboard connector on the motherboard. Be careful, this type of connector is fragile. On the left image the connector is closed. On the right image the connector is opened. Unlock the connector by moving the lock up as it shown on the right image and after that release the ribbon cable. Remove and replace the keyboard. For assembly instructions follow all the steps in the reverse order.


Hope it is helpful for you!

Thanks for using Fixya

How can i get to motherboard to replace it


You remove all the screws from the bottom of the case, remove the battery, open the case, remove all of the components on top of the motherboard, remove all of the screws securing the motherboard and then, finally, remove the motherboard. If you are very experienced it will take about 15 minutes. If you have never done it before it will take about an hour, you will damage some components and lose some screws in the process, and you will never get it back together again.

Good luck.
