  • 1. Replacing Hard Drive question
    I have a Compaq laptop with a defective hard drive which Compaq is replacing under warranty. They are shipping me the new hard drive and expect me to install it (with their help). Is this a very difficult procedure? I am relatively knowledgeable with computers and have replace drives in desktop units, no problem. I was under the impression that laptops are a whole different ball game though. -- Thanks in advance... Bob

  • 3. DC-AC Inverters
    Are the (relatively) cheap inverters I see on E-Bay adequate and safe to use with my Dell 5100? The specs say that the laptop uses 70W. If so, what's the right power rating - they see to come in all sizes?

First, of course, check the battery and/or external AC power supply 
(charger / adapter).

Otherwise, it probably is the motherboard, since everything is normally 
on the motherboard.  The problem could be very simple (a fuse) or very 
complex, but either way the motherboard is not normally considered to be 
a serviceable part, and it is unlikely that even an experienceed 
engineer / technican working on his own could repair it.

Thanks for your reply Barry, do you think it would be an expensiv
prospect to have this replaced?? Would i have to buy a NE
motherboard or would a used or refurbished one suffice?????

Also if I can get a used motherboard is it a straight forward proces
to replace it??

Many thank

My Sony laptop has a ribbon cable that connects the switch panel to 
the mother board. There are two small connectors, one on the switch 
panel and one on the mother board. If either is loose, no power, dead 

Just a thought.

Good luck, jimbo

Thanks Jimbo, but all fuses, connections were checked over by my T
repair man... and nothing was found but he did me the favour o
checking it out, although he's no laptop specialist!!

But thanks for the suggestion mate, appreciated nevertheless! :

Hi Jake.

Okay.. let's start from the beginning.. (Makes it easier for me this way) .

1. Is the AC Adapter working okay? you said you had a guy checking 
everything. If he works on TV's. he can check the Voltage on the AC ADAPTER. 
and tell you if it's working okay.. IF the AC isn't working and it died, 
then you would have used up all the battery power . thus the entire thing 
would appear DOA..

2. IF AC is good..Plug it into the Laptop, and REMOVE THE BATTERY from the 
Bottom / Side of your laptop .. then see if it powers ON ?

3. If this doesn't work . REMOVE the Hard Drive , Floppy/CD Rom drive. and 
battery and see if it will power up.

4. It may be the Power Button on the Laptop is not seating correctly , and 
if you can get the cover off , you can get to the little button under it, 
and press it to see if the Laptop Will Power up. ( this can USUALLY be 
accomplished By removing two or 3 screws from the bottom of the Laptop near 
the top where the power button is. horizontally and that piece VERY 
CAREFULLY can be removed.. Or the entire top will have to come off )  Don't 
mess with it if your not comfortable with it.

5 . Again make sure the LAPTOP LIGHTS are not coming on thru all this.. IF 
they are,  it may just be the LCD that is DOA and not lighting up for you.

6. At this point. Replacing the MotherBoard seems to be your only Viable 
option. Unless I've missed something someone else can think of?

Replacement of a MB is NOT something you would want to do yourself, 
especially if it's your first time, and the laptop belongs to someone else. 
Not something I suggest doing if you are not familiar with them, or have a 
knac for working on electronic devices taking them apart. etc ..

You did NOT say specifically which Toshiba it was. at this point you need to 
weight your options on EBAY for a used Laptop like his.. and swap his hard 
drive with it. ( letting him know of course) . or if it's cheaper to have 
the MB replaced by a qualified Technican ..

Good Luck .

3.Dead Battery = Dead Notebook ???

Ok here is a weird question.  Several weeks ago my 4 or 5 year old
Dell Inspiron 5000e laptop started having the following problems:

1.  If left to sit for several hours or after it was on for an
extended period of time it would hard power OFF (this wasn't because
of any power settings that I could find).

2.  The screen would be black after boot up.  I could hook it up to an
external monitor, but the LCD screen was black except for you could
just make out what was on the screen, but just barely.  Sometimes the
screen would work, other times it wouldn't, other times it would pop
up and start working after it had been on for 20 or 30 minutes.

2a.  The green light on the lcd case (lower left hand corner)  to
indicate the power was on would sometimes be lit and other times it
wouldn't.  This did NOT coincide with when the monitor was blank.

4.  Finally one evening it would not boot up at all.  It would start
to boot up but would just die like I had turned OFF the power.

Now, the apparent solution:  My battery had been useless for months
(about 2 - 3 min worth of power max) but I had kept it in the laptop.
Basically I could only use the laptop using the AC adapter.  Well I
removed the battery and everything seems to be working fine.

Finally my question.  Could this really have been the problem... a
dead battery?  Could a bad battery cause all these problems even when
on AC power?

5.When AC unplugged Power Meter keeps saying 100% batter power remaining


I have a problem with my laptop (which is ACER 5685, XP SP2, updated),
that when I unplug the AC cable then *quite often* the power meter
shows 100% all the time, obviously till the laptop abruptly switches
off when no more power is left. I'm not sure what should I reinstall
and how to solve the issue. Couldn't find anything about it in Google.
If anyone could suggest any possible solution to the problem, I would
be grateful.
