Doro PhoneEasy 410 some buttons won't work on keypad

It maybe a flex problem or keyboard problem. The reason why I said it maybe a flex problem is because flip phones are fond of having flex problems because of the constant open and close of the flip. It makes the flex wear/worn out.
And it maybe a mere disconnection.
Which ever the case maybe, the phone needs to be disassembled in order to check/know what's wrong.

When I open the keypad to use the keyboard, the phone screen stays in the vertical position rather than flipping to the horizontal position. what to do??

The flex cable of your phone between the keyboard and screen may be disconnected or needs to be replaced, which enables the screen flips when the keyboard is brought up. The best step here is to take it to the LG repair shop and get it mended. Though you can it is difficult to repair it yourself, you can use appropriate screwdrivers for the screws of the phone, find the flex cable and fix it. Close the phone just the way you opened it.

Acer Aspire 7735Z - how do you take the keyboard out?

Acer 7735Z

Carefully, Flip over the laptop with the lid closed (and at your knees), and remove the 3 across the top, then the middle one to the right of battery compartment, and the 2 to the left of the battery compartment.

Open the laptop, and lift the cover gently that houses the power button. Don't lift it right off as there is a cable connecting it to the laptop & you don't want to disconnect it. You can, but you don't have to.

Then, lift the keyboard up at the top of the assembly, carefully as you till need to take note of the direction the keyboard cable goes into the laptop. Pry up the brown cable retainer for the keyboard cable (it will swivel up 90 degrees), slide out the cable and remove the old keyboard assembly.

To install, put in cable, push back the cable retainer, slide keyboard assembly into laptop bottom first (you will see the tabs and where they fit). Replace the cover that houses the power button, it will snap down to help hold the top of the keyboard down. Close cover, flip over and replace the screws.

Unable to type

Flip the unit on its back and remove the battery.
Next remove the memory and hard drive.
In the memory area, you will find a lit. battery with a white 2 wire plug. Disconnect this plug and flip unit over.
Open the cover and hold down the power button for 30 seconds.
This will clear the BIOS and CMOS settings on the Laptop.
Flip the unit over and install the Hard drive and memory.
Next, plugin the battery connection.
Close unit up and plugin power connection.

Power up the 9000 and see if the keyboard is seen.

Note. You may have a defective or dammaged keyboard and may need to be replaced.
You can use a USB keyboard temp. About $20.00 USD at any Walmart
Hope this works for you.

Sony Ericsson P990i Flip keyboard not working

I had the same problem with my p990i. I stripped the flipped down and inspected the microswitch which gets activated when the flip is closed. The mountings and actuators get worne out after prolonged use. I cleaned everything out and reseated the switch correctly. Worked fine after that. If you do not have a bit of technical experience, i don't suggest you do it yourself. The ribbon cable is very easy to break.
Hope this helps
