donigspain: My HP Compaq Mini Laptop is faulty.
ORIGINAL KEYBOARD FAULT
- All the keys work except keys A S D F G Z C.
- Key Z repeats itself multiple times once you boot to desktop. Stop only when you hit the keyboard a little.
I was advised to get a new keyboard which I went for yesterday at Computer Village. I tried many keyboards but they kept repeating the following error sequence:
- All keys respond when punched
- Key Z no longer repeats itself
- When you press key A it displays AZ, key S displays SX, key D displays DC etc. and these are the keys that DON'T WORK in the original keyboard.
The technician cleaned the Keyboard Controller on the motherboard with brush (no spirit) and tried the keyboards again but it still repeated same errors. He now concluded that the Keyboard Controller is faulty and cannot be changed. I only have to make do with external keyboards.
MAIN-POINT:
Engineers in the house, what do you think of the above situation.
- Is the technician's diagnosis/troubleshooting correct?
- If yes, is the keyboard controller fixable/repairable?
- If yes, what will it cost me to fix it?

onegig: Sorry I wasn't around to attend to you. i guess you were the one that met with Gloria?

She explained to me what happened. I can't wrap my head around it yet. But I guess a bios reset and update is a sure way to go for now. It's the system and not the keyboard that's bad.

Given the above, it would appear that the laptop is suffering
from a software problem. In practice, a new keyboard should
have fix the issue. if that didn't fix it, the manuf's website would
be the next step. FAQ'S and software could be apply and see if it
happens again. What is actual model number of the laptop ?

We could do the followings

.check the bios by tabbing f1o to check for any
keyboard settings or reset the bios f9 and f10 to
save the changes

.secondly check the white or brown plastic pins on the laptop keyboard
were not bent during the installation of the keyboard.

When the new kb was installed, there was a slight improvement, however the Keys
continue to type two letters.

numericalguy: Hi computer engineers,

I'm using an Acer 32-bit laptop with the following configuration.
RAM - 1GB
Processor - 1.6GHz dual CPU (intel)
Operating system - Windows 7 Ultimate

The laptop has been slowing down of late and sometimes freezes up for like a minute which can be frustrating. I have a good anti virus and I have formatted the laptop several times but the problem still persist.

I'm currently thinking of upgrading the RAM to 3GB or 4G but I don't know if that would solve the problem.

As a trial and error, you could try upgrading the ram. however when diagnosing a slow system.
it is advisable to use google to narrow what might have caused it to slow. simply type make
your computer fast on google and follw all the advice on how to tweak the settings get rid of junks and
also memory. The general believe is that always install the default Operating system unless that cause a problem,
thee should be no need to upgrade. At the back of the laptop, there would be a model number, for example
acer aspire 5315, please check previous post before replying. Visit acer's website and have a look for windows 7.
if windows 7 is not on the acer's website, there is no point installing windows 7 because the architecture built into the system
can only manage the recommended operating system. the manufacturer's knows best. people often say that is okay to install any OS, but
professionally and realistically stick to default OS. Is like putting a toyota yaris engine oil into a a toyota avensis engine. although they are from the same manu'f but the archietecture built into the systems are completely different. to conclude, you can try upgrading the memory

These are the manufacturer's compatible operating system for your machine.
Having listed the compatible Operating system , would you check your system
properties using control panel on the start menu and ensure the operating system
type you have installed is on the list. for example, 32 bit windows 7 cd used on a
32 bit laptop. how did you format the laptop, e.g. cd or a pen drive to install the
windows 7. any blue screen recently ?

do you use generator of recent ?

any windows tweaking recently, windows
tweaking is where you change the settings
to a higher value. for example registry wait to kill 20000
to 1000

ikevin: thanks for the reply brof, 1-the LED light is on 2- the laptop indicates full charge within minutes of appearing to charge 3- I can't really say anything about anything loose in the laptop, but the laptop seems okay 4-the charger is good, nothing wrong with it as I have changed it twice 5-something is wrong with the laptop, do advise tech geeks, thanks in advance.

back to basics

does it turned on ?

have you tried with or
without the battery ?

i tihnk you're better off
buying another laptop rather than
repairining it. This is the last resort.

lowgeorge: Morning pple, pls my system is nt displaying despite d coming on of d laptop. I had a power surge issue yesterday which spoilt d charger I replaced it but its nt displaying at all just d processor fan spinning...pls I nedd a urgent advice on what next to do.

ATX Reset
If you have had any issues with you computer and phoned the help line number one of the common things they will ask you to do is an ATX reset, Basically this just resets the power supply in your computer and in most cases can solve some power and display issues.

How to perform an ATX reset:

Disconnect the power from your computer.
If possible remove the battery and external devices.
Hold the power button for about 15 seconds
Put the battery back in the computer
Reconnect the power
Press the power button to turn on your computer

If this does not solve the power issue it may be the hardware its self which is faulty and will need repairing or replacing.

Input: Hello house, my laptop (HP 2000) all of a sudden crashed so to say.
Everything was working perfectly before it was shut down, after some hours I switched it on only to discover it has been restored to its original state as if it was formatted.

Now I can't see any of my files even though the space on the hard drive is still the same prior to this attack I.e the used space was not altered.

Please how can I restore my laptop to it's previous state or how can I get my files back intact.

This is 50/50 kind of thing but it worth trying.
download recuva and follow the instructions on how
to use it

ikevin: Good evening to tech guys in the house, my laptop is not charging my battery. The battery is new, i've taken to a technician, he thought it was IC problem but later said nope and gave up. I've been using it like that, what can I do abeg Oº°˚˚˚° .

The technician assumed that the IC was faulty, but we need t o be sure that the tec
has carried out some basic test. plug the charger, can you see the charger LED light on the
laptop that indicate the laptop is charging. can you feel anything loose inside the laptop ? try wigging the
charger as you connect to the laptop and see if you can feel anything loose inside. the charger would
give you that feeling once you connect. try wiggling it and see if any LED light blinks as well

saintruky: Please help oooo... My newly bought hp laptop is exposed to virus. Anti-virus that came with it lasted for a single month. Malware has been attacking the pc seriously. Please which is the best anti virus to use and what is the cost? Someone come to my aid asap.

I would recommend superantispyware. you can search for it on google and make
sure you download the free one. Open the downloaded software and scan your

computer. you would most likely find 250 if not a thousand junks. After you have scanned
your machine, scan it again. After that uninstall the software, as in delete the software

in control panel add/remove programs. This is ensure that the current installation does not
interfere with the new one. after that head to google and download microsoft security essential.
make sure you update the new antivirus.

topstar80: ...it has worked before....I just saw both the WiFi and Bluetooth switch fade compared to the airplane mode

I can get my head around this, may i ask ?

how do you normally switch on your wifi, e.g. fn+ f ? key

do you mean the wifi and the bluetooth icons disappeared d ?
if it has, have you check desktop notification settings ?

ok right click on thestart menu on your windows 8 and click contro panel
then look for system information the device manager click the + sign next to
device manager and tell us what is there. for example atheros wifi adaptor, can
you any exclamation mark ? when did it last worked precisely ?

I can't believe you didin't check the back cover when you received the laptop.

so obvious you would examine it. wont you ? good it works anyway

confused to what might happen.no repairs has been made in anyways,

And also have you try to type using ms word or type using the internet
with the keys mentioned ? you could blow compress air into the keys mentioned and
see if it will get rid of dirt and eventually work

Shut down the laptop, removed battery and cable for a moment,
press and hold the start button for 60 seconds... and replace the battery..
start the lap top.. if that does not work a technician is a must.

ahmedgafar7: bro, did that like a 100 times

5 years ago when I used to work for with DSGI
international Business support, it is a requirement to
do this. Failure to do it on several occasion, could lead to
warning for the agent and if that happens again. The agent
could be invited for a disciplinary meeting. This works alot and have saved many
business owners machine from coming to our repair line

So I will forever try this on issues such as no display, no power and so on.

martinmiller: nice topic,i knew you are one of the compu gurus onNL..
