Question about PC Laptops

Toshiba Notebook won't boot or post even to bios.

It's a Toshiba Notebook with Celeron M processor and 512mb RAM. I am unsure of the model. It's running windows XP Home.

When I push the power button, the fans and lights come on, but then the fans wind down and go quiet pretty quickly. The screen never lights up, I can't get to safe mode. The only sign of life left is that the power light is on. The hard drive doesn't seem to be getting accessed either.

I have tried hooking up an external display via the VGA adapter and it does nothing. I have tried putting new RAM in it, as well as removing the existing RAM altogether with no changes.

I have also tried removing the battery, unplugging the power cord and holding the power button down for 15-20 seconds. Also tried leaving the battery out and just plugging in the power source and still nothing.

My guess is that it's either the mobo or something to do with the display.

Any suggestions or idea's to back my guess up?

    I have a durabook with exactly the same problems. Can't keep the thing up long enough to change bios settings to get it to boot from a CD. BIOS battery? Mother board???

    I have no warranty, no USB devices plugged in, I have tried re-seating the hard drive with no changes. I guess it's a motherboard or board power regulator issue. Guess I'll make some calls to see what it will cost to get this thing fixed.

    Thanks for the response.

Hi oneride21 and Tina3496,
Generally the syptoms sound like the motherboard on your laptop has died or on board power regulator. There are however a few more things you can try before going to a new laptop or claiming warranty if you can.
1. Have you tried reseating the hard drive? You will need to locate your hard drive and unplug it (There will be a few things you will need to unscrew, but generally no more than 3 screws) then try and power on.
2. do you have any other USB devices attached? if so unplug and try again.
3. When you plug in your powersupply, does a amber light show. If not, your laptop is dead and chances are it's going to be cheaper to get a new one, as laptops for most home users that surf the web and do a bit of word processing are fairly cheap.
4. If none of these work, dounble check your warranty on the laptop, most come with a 1 year hardware warranty, but you may have a 3 year one, so it's worth a check.
Hope this helps, let us know if you have any more questions or how you have got on.
Cheers CptHaddock

    Thanks for posting how you got on. Don't forget that fixing it may not be the cheapest option., Brand new could be a better choice. Shop around once you have a quote for fixing your laptop. Don't forget that you can recycle your laptop hard drive to be a portable hard drive. All you need is a 2.5" caddy that most PC shops sell for around $30 NZD.

My Wifi is not working. My laptop sound is scratchy. I want to upgrade my processor from celeron to core 2 duo which one i should select for cpu upgrade?


Two main things to know before you can attempt a Processor upgrade.

1) What Processor socket is on the motherboard?

2) What motherboard chipset is on the motherboard?
(Northbridge and Southbridge chip. Unless it's a motherboard that supports Intel Core 13, Core i5, Core i7, and Core i9 processors)



According to specifications I found online just now, the BenQ Joybook A53 comes with an,
Intel Core2 Duo T7250 processor,

http://laptops.techfresh.net/benq-joybook-a53/

Scroll down.

(Only 512MB's of DDR2 Sdram (SO-DIMM) ram memory that operates at 667Megahertz?
{ PC2-5300} Yecch! You need at LEAST 1GB of ram memory. (512MB + 512MB = 1GB.
2GB would be best)

http://www.laptop-software.com/benq/benq-joybook-a53-features-and-specifications/

Information on the Intel mobile Core2 Duo T7250 processor,

http://en.wikipedia.org/wiki/List_of_Intel_Core_2_microprocessors#Core_2_Duo_2

Scroll the page down until in the left column you see T7250. Then read across, and match the headings above.

Is your problem directed to a BenQ Joybook A53 Notebook PC, or is it another model?

* If it's a BIOS problem, try this :

1. Shutdown ur system, and remove the BIOS battery.
2. Reinstall it and start again.
3. You can also replace the battery. (if above steps don't works!)
4. Try to get a updated version of BIOS driver. (if above steps don't works!)

* If u r also hearing any kind of beep sounds, it may be bad RAM (memory). Try this :

Can i upgrade my processor?on my toshiba satellite m55-s135 laptop? I am upgrading the ram from 512mb to 2gb and the hard drive to 200gb.


dont know what processor you have. If you have a celeron M you can probably upgrade to a pentium M without any problem. The ram you should check. I believe that motherboard will only support 1.5 gb. Any more you will be waisting your money.

I want to upgrade my hpdv1000 pentium M processor whats the maximum upgrade allowed for this? i have upgraded it to 2gb ram from 512mb and 250gb hd from 60gb and its doin fine.


You should be able to upgrade the CPU, since it seems that the DV1000's motherboard uses a socket CPU design. But, obviously, HP would rather have you choose the CPU that you want from the beginning and stick with it.
The first thing to do is to check HP website to see what other configurations were/are sold for your model. If they sell it with faster CPUs then you can upgrade to one of them...

PLEASE NOTE:
In order for a particular processor to be compatible with a particular laptop:
(1) the processor must be physically compatible with the laptop socket, in your case I thing you have a Soket 479 processor
(2) the laptop chipset must support the processor.
(3) the chipset front side bus speed must match the processor front side bus speed, in your case 400Mhz.
(4) the laptop BIOS must support the processor.

So I listed here processors with FSB at 400Mhz, I gues that DV1000 as a 855GM Motherboard that supports only 400Mhz with Socket 479

Pentium M 755 2000 2048 400
