Hi, I have a Sharp AL27 that recently just got over a huge crash. It had a power shot and the hard drive had to be replaced but anyway, the keyboard after this time has started giving me problems. It seems to randomly stop working when the motherboard loses power say when unplugged and the battery dies which is in about 10 mins. But if left plugged in the thing is fine. I have to pull out the ribbon cable and plug it back in while the laptop is on and then it works. Although i have noticed when its working the icons on the desktop will start flashing as if a button is stuck down somewhere and the mouse flashes as if the computer is busy and when the computer starts up it asks me how i want to start windows and only does that when the laptop keyboard works. Other then that the computer works great but does this sound like a motherboard problem, and hopefully not, or more of a keyboard problem? If keyboard do you know where i could find one to buy? Thank you Kyle

Re: Keyboard randomly stops working
If this only occurs on battery power and your battery only holds a 10 minute charge? And your keyboard is external (PS2, or USB) it draws power from that battery (even the OEM keyboard does) and is probably glitching on you for lack of power. That's of course if I have understood you correctly? Good luck.

You need a 512MB
PC2700 DDR 333MHz SO-DIMM for a laptop (200-pin). The
manufacturer I think doesn't specifically support anything over 512MB. But the RAM is standard and I doubt there is any need to buy it directly from Sharp. The laptop only has one upgradable bay so you may not be able to upgrade past 1.25 GB.
One of the memory covers is not removable, if I remember correctly, that is the one under the keyboard. So the one you update is a panel on the bottom.
If the computer is dead the only way to recover the files would be to remove the hdd & install it as a secondary hdd in another system in order to copy the files. After you are sure all your data is copied you could then either reformatt & keep as a storage drive in other system or remove. You'll need the proper cables as most laptop hdd's just slide into a built in port on the laptop's mb. Hope this helps.
I fixed the problem by going to "Device Manager," then to the "Universal Bus". Under "Universal Bus" are a list of the individual USB ports. You have to delete each one individually. When you delete each one, a window opens up which gives you various headers; select "drivers" and hit "uninstall". When you hit "uninstall", windows will ask if you want to proceed. Select "Yes". You'll then get a "warning" that the computer may not work correctly if do this procedure. You want to proceed with the deletion of each Universal Bus port. Once you've removed the Universal Bus ports, then reboot windows. Windows will detect the individual Bus ports and find new drivers for them. Once the drivers are installed (automatically by Windows), the USB ports will be operational.
There was a post I read on a notebook forum site that deals with a BIOS problem with the Sharp Actius PCAL27 from a guy named fixyourlaptop AT yahoo DOT com. He stated that he was a Sharp tech, and that the main problem with the AL27 is not the battery, but the BIOS.
There is apparently an issue with these BIOS that causes the power usage of the battery to show incorrectly. I purchased my laptop over three years ago, and just recently updated the BIOS sent me by this fellow, and my laptop battery discharges properly. It still only has about an hour of life but this is the first time it ever worked right.
You can email him for the fix at the above address. Just put in the subject line SHARP LAPTOP AL27 BIOS FIX. He is legit and the fix worked like a charm.
If you want to read his post just do a search for the above (properly formatted) email address on google.
