SantapG thanks for your offer to help! I have an old computer which aint working now! When I took it to a nearby hardware engineer he checked it and informed that the motherboard is not working and is dead. Do we have any method to find out if the motherboard is gone? If at all my motherboard is not functioning what could be the possible reasons and how can we fix it?

This is good.Vendors and troubleshooters should visit this form often. Welcome to the forum Sandip.

Don't leave your battery unused for long periods of time. Even if you use AC power most of the time, use the battery regularly to keep it in good condition. Switch off your AC adapter when the laptop is not in use. This prevents overcharging.
To extend battery life, you can try decreasing the LCD brightness while using your notebook. You can activate the `Standby' and `Hibernation' power saving modes, too, for better battery life, you can put off the Wi-Fi when not in use.
If you do not use your laptop for extended periods of time-a week or more remove the battery pack from the laptop, but only after discharging it fully.
No eating and drinking near or around your laptop. The least bit of water could short-circuit some sensitive laptop circuits, and render it useless.
You may sometimes be tempted to turn your laptop off by simply holding down the power button until it powers down. Although quick, this method is harmful to the laptop and could cause data loss. A hard reboot should only be used as a last resort. Sometimes this is inevitable, for instance, when Windows hangs. But this should not be a regular practice.
Don't subject your laptop to jerks and shocks. This will help avoid damage to your hard drive. Preferably, power the notebook off before moving it from one place to another.
External peripherals and accessories such as external optical drives, PC cards and USB keyboard lights draw power from the notebook. Disconnect such devices when not in use.
Booting the notebook when it is not connected to a power source draws a lot of power from the battery. Instead of shutting down your laptop in the middle of a meeting, choose the `Suspend' mode if you wish to use it again after just a short interval. This will save battery and help you restart your work faster.
If you have just shut down your laptop, give it 30 seconds before you start it up again. This ensures that the hard drive has spun down, and is not subjected to sudden switching on and off.
Don’t put on the laptop keeping of cloth or bed because generally the air flow is from bottom, regular doing so may reduce the life of laptop circuit.
Don’t press very hard the laptop keyboard because, if damaged can cost very high, therefore while playing game use external keyboard.

In Case u want to mail me ur problems my e-mail address is info@compudrivesystem.com

Guide To Purchase Secondhand Laptop

Laptop is used to carry from place to place…so people who travel a lot must think of the weight of the laptop.
Every battery has a lifetime. So going for a Laptop with hardly any battery backup is not suggested. Minimum of 45 minutes battery backup is very necessary. So while purchasing the secondhand laptop please keep in mind to check the laptop only on battery for minimum 30 minutes and also keep an eye on battery usage indicator.
Carry with yourself an audio, video & Blank CD/DVD so that u can check the audio section and video section of the laptop including the CD/DVD read/write test.
Run the scandisk utility available in all versions of windows and check for bad sector in hard disk.
Take with yourself any external device like thumb drive to test the USB port.
Take with yourself SD memory card to test Card Reader (If the option is available on the laptop)
Take any good floppy to test the floppy drive (Any how current Laptops are not coming with Floppy Drive)
Take an external headphone and microphone to test the external audio port.
Attach the laptop to the external monitor to check the external VGA port is working or not.
Open any word file and check all the keys are working or not.
Check for battery charging for 5 to 10 minutes and see the battery indicator is showing charging.
Press the window and the break keys on the keyboard and see the amount of RAM and CPU details. Further chick the hardware option and then the Device manager to see all driver are installed or not. There should be no Exclamation mark.
Slide the LCD screen slowly on the hinges and check any flicker on the display if so there may be a problem on the connector cable driving the LCD circuit of the laptop.
Also check the Modem, Bluetooth & Wi-Fi Port if available on your laptop to be purchased (Do only if you know) I will be writing on these subject next.
Check the laptop minimum for 45 minutes to see whether laptop hangs or restarts or shutdowns.
See the Laptop User manual and Driver CD are there with the Laptop.
See that u get a laptop carry case, otherwise u have to purchase one.
If all the conditions meets out OK and within your budget just go for it.
Happy LAPTOPing.

I have one question...

If you read the charger it says between 110v to 240v.... now one thing all vendors here at Kolkata say when you by a notebook, dont charge it on Genrator or Inverter power !!!

As you are in this feild please tell me are todays moderm notebooks can be charged on inverter / Generator power ?? the question is not only about Notebook charger, I was adviced dont run the TV on generator because of flactuating voltage, while my 7 year old Philips power vission is running quote fine on generator or under inverter !!!

So please shade some light on it !!

thnx...

S

Hi: Chota Cheeta

Nice to have your question and nice that u r from kolkata because i belong to the same place.

Now Power supply from generator or Invertor generally voltage is OK But the concerned factor is the frequncy and the wave shape of the output what we get is not sine wave and even not 50 hertz, so therefore we should not run any hi ended electronics devices on such available power supply. But there are cases where u have no choise, then one can take the risk.

Sandip,

Your message could be a godsend for me. I have a problem which is really bothering me !

I have a presario SR 1930 IL. It had 512 MB memory as supplied by Compaq. I put another 1 GB memory (same frequency) in the second slot. The computer does not read second memory, it keeps showing 512 MB only.

However, when we removed 512 MB, it worked fine with 1 GB RAM. We tried all sorts of things such as changing the slots etc. In between, it started showing both memories. After about 5 - 6 days, the 1 GB disappeared again !

Thinking it is a compatibility problem only, I ordered another identical 1 GB memory. Again, it is showing only one memory of 1 GB. It does not read both memories. I am at my wit's end.

I am now running the computer with one 1 GB RAM, in the slot which NOT read if both memories are there. It seems to be running OK right now as I type it.

It is really bothering me. Can you help ? I am in Kolkata too and we can talk if u like. If you leave a msg, I will give u a call.

nice info mate

good 2 see u such handfull hands on da forum

.

dear santapg,
most of us here have assembled our own desktops but very few of us know details of laptop hardware.
can you advise if its reasonable to assemble our own laptops.
Please advise on component details, availability and info necessary for the same.
Also, since tablet pcs are not available easily in India,, can you please also tell us more about the Penabled tablet screen, how and where to get it and if possible, how to build a tablet. I have also come across screen digitizers for the laptop which can be used to convert a normal laptop lcd into a tablet. I hope these are not exotic gadgets and it is possible to build such a customized laptop. Kindly reply in detail. Shall look forward to your comments.

Assembling a laptop is no difficult task either. But the hardware needed (barebones, component choices, etc.) don't have any retail presence in India. Meaning you don't get the stuff you need to build a laptop from scratch in the market.

So, buying a branded notebook PC is the only option. Now that there are hundreds of options to choose from, it's not difficult to find the laptop of your choice in the given budget. Dell also offers some basic customization in their laptops sold in India. So, you can always resort to their systems.

S

See as far as the IT has proceeded assembly laptop in large scale is possible but not one for u and me. So think of going for a good brand.

Hello santapg.. was relieved to hear that u've had an experience since 16 years...

hope you can help me.

The problem with my old Celeron PC ( Pentium 3 era) is that
When i turn it on, it does not POST. The Motherboard has a light which lights up. The fans are working. The CPU gets hot... i touched it after turning it off.
The RAM is working.
The monitor shoes "No SIGNAL"
Initially after warming it up by leaving it in the conditon for 1 hour or so and then restarting it solved the problem.

slowly it had to be kept overnight and then from one day it wouldn't ever start.

My speculation is that the motherboard has gone dead.

and 3 of my friends having similarly aged Computers with similar specification face the same problem.

One of them does not start at all.
One of them starts but like my initial problem . Sometimes it does, sometimes after warming up.
the other has similar problems.

All in all there are 4 of us and the computer are really old ~ 5 years or so.

Is it because the capacitors have gone dead?

but i have seen people getting it repaired without replacing the motherboard as well..

could you help me?

S

It is a matrix controller problem with your laptop. It is repairable. we have to change the matrix controller or it can be also dry solder some where.

Hello Santapg, i have a compaq presario V3000 V3424av. My problem is that the laptop has been damaged. The company repairers have told it is a motherboard problem and that the repair or change will cost me 16 000 Rs/-!! 16 K is too much i guess, so would you please inform me whether the said amount is true? or any other advice would help. I reside in chennai. BTW its been exactly one year and i have lost the warranty.

one fine day my motherboard start beeps 5 times but no display on my screen and
than no motion from my cpu.the fan and processor do starts and graphic card too but only for 5 seconds than everything goes stand still.i contacted asus customer care and they respond this---
Thank you for contacting ASUS Customer Service.

My name is Jany and it is my pleasure to help you with your problem today.

Do you mean that the PC now could not POST?
If yes, please clear CMOS as the following steps:
1)Turn off the computer and unplug the power cord.
2)Remove the BIOS battery.
3)Move the clrtc1(besides the battery) jumper caps from [1-2] to [2-3]
for 5-10 seconds,then put the jumper caps back to the original position, [1-2].
4) Re-install the battery.
5) Plug the power cord and turn ON the computer.
6) If you can go to bios then, load default settings, save and exit.
If it is not helpful, I suggest you to take the motherboard out of case and keep the necessary components(a CPU, one memory, a graphic card) onboard for a test.
If the problem still exists,
1, Please take out your memory cards and graphics card, try to clean their golden connectors with a rubber, then reseat them back.
2, Please take the CPU cooler out, add some thermal paste to the CPU surface, then reseat the cooler back and keep the cooler tightly installed.
If the problem still persists, if convenience, please change the necessary components to test again.
If it is still not helpful and your retailer could not help you, please let me know. Thanks for your cooperation.
but to my surprise there is definitely a three pin near cmos battery,but there is no cap on it,do that is the problem which is creating no display .please help me!!!
