Question about Computers & Internet

1 Answer

I have a few keys that are not responding to touch (F5, F6, 5, 6). There was a small spillage on the keyboard approx 5ml juice which has now all dried out. I have taken the key covers off to try and press the actual key but this still does not work. I would appreciate any advice on how to resolve this problem as my laptop is now out of warranty. Many thanks

The only thing that you can do is to replace keyboard. Google model of your laptop and add word keyboard to it,check eBay also. If you don't have manual/user guide for your machine check maker's website/support. It is not that hard - just go nice and slow.Good Luck! var geo_Partner = '20df8a9f-0e62-447d-a13b-e4b279000c5f'; var geo_isCG = true;

Problem with keyboard, tiny water spillage, big damage


How to enable On-Screen Keyboard in Ubuntu 10.04 (Lucid Lynx)

Turning on the on-screen keyboard in Ubuntu Linux is a little more complicated than it should be. These tips should work for any version of Ubuntu within the last few years, but I'm using Ubuntu version 10.04 Lucid Lynx.

The simple way to enable the on-screen keyboard is to run the program from the Terminal:
$ onboard

However, if you cannot use the keyboard, you cannot type. On to method 2:

  • Go to System -> Preferences -> Assistive Technologies in the Ubuntu menu.
  • Select "Enable assistive technologies".
  • Click "Preferred Applications".
  • Under Mobility, select onBoard from the drop-down menu. Check "Run at start".
  • Log out and log back in, and the On Screen Keyboard is now enabled.

If you want to enable the on-screen keyboard at the login screen, please read my VMware Lucid Lynx guide, it's explained as part of that tutorial.

Scan for Viruses

Sudden, unexplained computer issues are commonly caused by a virus infestation. These sneaky programs secretly install themselves on your system and alter the way the machine functions and responds to commands. Eliminate any hidden malicious programs by running a deep scan to find and destroy unwanted programs. You may need to perform a restore or recovery action on your system afterward to replace corrupted files with the correct versions.
Troubleshooting

To determine whether your non-functioning F5 key is due to a software issue or faulty hardware, connect a separate keyboard to your Pavilion. If the F5 key works on the external keyboard, the problem with your Pavilion's F5 key could be physical, such as a dirty key or spilled liquid. If the F5 key does not work on the external keyboard either, the problem likely lies in the software. Make sure that your operating system files are up-to-date to encourage proper communication between the keyboard and motherboard.

Thorough Cleaning

A keyboard key can become non-functional if it cannot make contact with the proper sensor beneath it, such as from accumulated debris or a spilled liquid. Dust, hair and lint can collect beneath and between your Pavilion's keys, which can interfere with proper contact when the layer becomes too thick. Sticky residue left behind by sugary liquids, such as soda or juice, can cause the key to stick, preventing the computer from registering the press. Thoroughly clean the area beneath the F5 key by gently prying the key off and using a cotton swab and rubbing alcohol to remove any dirt or residue.
Safe Mode

When you start your Pavilion, numerous other programs automatically start with it. Any of these programs could cause the F5 key to become non-responsive. Starting the Pavilion in Safe Mode will load only the essential operating system files and drivers, and if the F5 key works while in this mode, your problem most likely lies with an installed program or hardware device. To enter Safe Mode, restart your laptop and press the F8 key immediately. You'll enter the "Advanced Boot Options" menu, where you can use your arrow keys to select "Safe Mode" and press "Enter." If your F5 key still does not work, you may have a problem with your operating system files.

My keyboard works except some keys are not working?


Your question is not specific about specifically which keys work and which keys do not work and exactly what you mean by the keys not working, whether you mean there is no reaction at all when the relevant keys are pressed or whether it is just that incorrect characters result from pressing these keys.

If incorrect characters result from pressing certain keys towards the right of the keyboard, use the Fn key, bottom left, pressed simultaneously with the Num Lock key, top right, to toggle 'on' or toggle 'off' the Alternative Symbol function of some of the multi-function keys.

If there is no reaction at all when you press a significant number of keys, then there may have been liquid spillage damage to the NetBook. Liquid spillage damage can sometimes be resolved by partial disassembly of a NetBook/Notebook and wiping congealed liquids off with mild solvent or allowing internalized water to evaporate. This type of repair is best done by an experienced NetBook/Notebook repair center or technician.

If only one or two or a small number of keys do not work, then it might be that particles of some or other substance, trapped underneath the keys might be interfering with the function of the non-functioning keys. This can sometimes be resolved simply by inverting and gently shaking the NetBookso that any trapped particles come loose and fall out. Occasionally, individual key caps have to be removed and replaced after the obstructing particle has been removed.

If several keys are defective but the fault was not caused by liquid spillage or trapped particles, then the keyboard unit itself might be faulty and need to have its internal ribbon cable and cable connectors tested for cable damage or connector damage (typically either from liquid spillage, shock caused by dropping the computer or by previous unprofessional internal repairs). If no fault is found with the cable or the cable connectors, then the entire keyboard unit may have to be replaced.

The FN key stopped working from nothing, pressing FN + F3 or f4 or f5 or f6 or f7 nothing happens


Its probably just a broken key on the keyboard. If you know someone with a usb keyboard then plug it in and see if the FN key on that responds. if it does then it is the keyboard at fault.I would buy a new keyboard.

On my acer 5742-7645 my touchpad has stoped working?


Hi,

Just check for the key combination on your keyboard (ex. Fn + F4 or F5..depends on the what key was designed for the touchpad), the touchpad might be locked.

If it is not locked, reinstall the touchpad driver, but it this still doesn't work, boot to Safe Mode to check if it does. Touch pad still not responding in Safe Mode would mean hardware failure.

Hope this helps.

My keyboard is not working right keys E,D,C,3,F4 &F5 are not responding when I use it, thats why i'm using on-screen keyboard often times.


It could be a bad connection. The keyboard is usally pretty easy to remove. On most labtops it can be removed with a small screwdriver along the edge of the keybord. It is connected to the motherboard with a brezel connector, check that it is not loose. If you cant find the fault you can normally find a replacement keyboard on ebay for as low as 20 bucks.

What is the best way to prevent spillage from messing up the keyboard


It depends on what kind of spillage. Unless you can find some cover to put over the keyboard, the simplest solution is to keep ALL LIQUIDS as far away from the computer as you can manage.
however, depending on the type of liquid, you can in most cases, if your fast enough, you can wipe off the spill, or disconnect the keyboard and pop the keys off to clean underneath. (keeping sure not to touch the circuit board underneath). Most desktop keyboards allow you to do this quite easily (just make sure to do them one by one- the last thing you need, is to forget where each key is supposed to go, and put for example the "K" key where the "G" key is supposed to be. ) a quick response is especially needed for spillages with sticky liquids, such as Orange Juice or Coke/Pepsi (a computer service tech's worst nightmare) or liquids that will dry with a thick stain, such as coffee/milk products.If the problem is just water however- leave it out to dry for a few days in a really warm, dry place. The board should work with no problems afterwards.
Hope this helps!

Can't refit space bar & alt Gr keys to Acer Extensa 4620


Removing the keys can sometimes damage the very small retaining clips then it won't clip back in place.
You can get replacement keyboards on the Internet, I've bought keyboards for approx. US$20 from the USA. The keyboard is easy to remove and replace, no need to get a techo to do it.

Spilled Grape Juice


To give it a good cleaning, you will need to remove the keyboard and clean anywhere you can see juice or feel stickiness. You can buy the expensive computer cleaners, but I suggest 50/50 rubbing alcohol and Q-tips. Remove the battery and C-mos battery to make sure there is absolutely no power to the machine what so ever. After cleaning inside, you will want to give it a good 24 hours to dry, ensure that there is no moisture before applying power. If the juice reached the bottom of the machine, you may need to remove the screen, split the cases, and take the motherboard out, in order to clean the bottom side of the board. If you leave juice anywhere on the board it will gum up, and the acids in the juice will corrode and detierate the circuitry on the board causing a motherboard failure. Now the keyboard, in order to thoroughly clean the keyboard, I suggest that you spray a good amount of the rubbing alcohol in the keyboard, shake it or blow it out with air, then take paper towels and daub up the rest. Repeat this two or three times, then let it dry approx 24 hours. Sometimes the keyboard won't recover after a spill and will need replaced. If it works properly, then, after using the keyboard for a while, you will notice if any of the keys are sticking. Take the sticky key or keys off and clean them individually. I know it's alot of work, but it'll teach you not to keep open drinks around your laptop. It did me, I've ruined one machine, two keyboards, and thoroughly cleaned a third very expensive machine of mine to keep it working, but I finally learned to drink from a sippy around my laptops.
