Laptop wont turn on, got green pwr and amb bat but will not fire up


Systems covered: All failing to boot without lighting up display.

Goal of this Solution: Try to determine whether system is (a) booting successfully while failing to light its display (indicating hardware failure in the display), or (b) failing to light the display due to failure to successfully transfer control to ROM BIOS (indicating a motherboard failure).

The fact that the Green power LED, and Amber Battery LED are lit seems to exonerate the laptop power supply (brick) circuitry. Even with a nearly dead battery, a Toshiba Satellite 1135-s1552 should work while plugged into a properly functioning brick.

Here's Toshiba support's (244 page) online PDF version of your laptop manual:
http://www.csd.toshiba.com/cgi-bin/tais/support/jsp/modelContent.jsp?ct=SB&os=&category=&moid=434997&rpn=PS113U&modelFilter=1135-S1552&selCategory=2756709&selFamily=1073768663

If the HDD (hard disk) activity indicator LED is active after power-on, then your system has actually got past BIOS and is booting - your LCD monitor inverter circuit or Backlight may have burned out - and to use the system, you'll need to connect an external monitor to the RGB monitor port on the back of the system (see illustration on page 32 of User's Guide) to view system activity.
Alternatively, one may attach an analog TV, using the S-Video port on the back of the laptop (see illustration on page 32 of User's Guide).

Once an external monitor is working to display the ROM BIOS part of the boot sequence, you may find that the ROM BIOS is good enough to run a few BIOS-based diagnostics. Run them all - something may indicate the source of the boot failure. Ofttimes, enough of the motherboard remains good to provide interaction with the ROM BIOS, but some motherboard failure will subvert a full boot to Windows/Linux. An example of this type of failure would be a failure of the PCMCIA bus controller, which is vital for booting a disk-resident OS, but unaccessed (except by BIOS diags) when the user interacts with BIOS. Another common failure of this type is main memory (RAM) failure.
A working external monitor/TV also provides a chance to backup important laptop data to a flash drive, sky drive, or CD-RW discs.

If no HDD activity is seen after power-up, then either your BIOS is hosed (in which case you'll need a new motherboard), or another motherboard component is hosed (in which case you'll need a new motherboard).

You may want to transplant the HDD into a working PCMCIA-bus system (any laptop) to recover/backup your important data.
If someone recently attempted and failed to update the motherboard's ROM BIOS, then you know why the system is failing to boot and also failing to light the display.
Here's a link to a site with disassembly instructions for Toshiba laptops:
http://www.irisvista.com/

Most dead laptops (even those whose power supplies have been burned out by a nearby lightning strike with the system on 120 VAC power) will still have perfectly usable HDD module(s), and RAM memory cards, so that at the very least, these removable components may be recycled into memory reserves for your next laptop or sold (Ebay.com) to help defray the cost of a new system.

Display not availabl


Do you know how to go to the bios settings? It depends on your machine model. You can press F2 or F10 to go to the BIOS settings continuously as the computer starts booting. Can you see anything when you try entering the bios settings? If so, then boot from then you have to boot from an operating system cd.If you cant see anything while in the BIOS settings, then you have try another monitor.

No bios booting on start up


The model number you provided is incorrect.
It is most likely, D945GCNL. Intel site for your MB; http://downloadcenter.intel.com/SearchResult.aspx?lang=eng

If you’re currently using 2 DIMMs of memory remove one DIMM. Open your manual to page 11. First remove DIMM "L". Attempt booting your system. Listen for possible bios beeps. Than shut the system down and remove the memory from " K " and insert your second memory DIMM. Again, boot system and listen for bios beeps. Intel suggest when installing memory on to the D945GCNL motherboard that it be done in a specific manner. See, 1.4 System Memory Page 16, in the TechProdSpec.pdf manual provided below; http://downloadmirror.intel.com/15115/eng/D945GCNL_TechProdSpec.pdf
The power supply currently in your system with does not provide enough wattage for your motherboard. To help find how much power you do need open the next link provided; http://www.journeysystems.com/?power_supply_calculator
It’s better to have more wattage power than you need. Even though you have an Intel manual for your board it’s suggested you download it from Intel. You'll need Adobe reader to view the manual. With Adobe you can use the zoom in feature. The next pdf link is your manual;
http://downloadmirror.intel.com/15115/eng/D945GCNL_ProductGuide02_English.pdf
I do not think there is anything wrong with you bios or your system memory. I think your system is under powered.

Happy holidays!

I have asus p5p800-mx mother board morboard working fine and also start but on monitor no display and i also try to install additional graphics card then also no display


Have you tested the monitor to see if it is working? Is the vga cable good? Are you getting the BIOS start-up display screens when computer is booting up or no display at all? It is odd that both the on board video and video card would be bad I would double check the cable connection and the monitor. If the cable is good and the monitor is working properly than the board might be bad. You should at least get the BIOS start-up screen display.

Monitor going right to sleep mode on start up


Sounds like a bad graphics card. Try using monitor wit another computer and see if the problem still exists. This rules out the display.

Corrupted screen display even at BIOS startup


The bios boots without loading the Graphics drivers. The problem is with the monitor itself.
Buy a new monitor. Keep an eye out on www.newegg.com they often sell monitors at 22" for 169.00

Motherboard installation


Hello mecompe,

If you installed an AGP graphics card before your fist boot of the system, you will not receive display. By default the onboard graphics is set to boot display. (If this is the case, remove the AGP graphics card & boot the system). The Asus P4SGX-MX can only use a 4x AGP 1.5volt (only) card.

There is an order of sequences to perform before installing/ adding an AGP graphics card on to the board when the board also uses an integrated graphics card.
First, shut down the system & unplug the power supply from the PC. Connect your monitor to the VGA port at the rear of the board. Remove the AGP card. Re-connect the power supply & boot the system. You should have display? Re-boot the system. As the system starts up press the delete key on the keyboard every 2 seconds. The bios main menu will load. (Open your manual). Go to
section 2.4.3, page 2-20 under Advanced, PCI configuration. Set Primary VGA bios to
[AGP VGA Card]. Save the bios & exit. The system will auto restart. Press & hold the power on/ off button on the PC case until the system shuts off. Unplug the power cord from the PC. Insert the AGP card into the AGP slot. Connect your monitor to the AGP card.
Check all internal data & power cables, (Incase something came loose). Re-connect the power cord & boot the system. You should have display! Install your video software.
If your using the integrated VGA PCI graphics card, go over the bios settings page 2-18 & 2-20.

Need the Asus manual? Click this link;
http://support.asus.com/download/download.aspx?modelname=P4SGX-MX&SLanguage=en-us

To view the manual you'll also need Adobe PDF reader, click this next link for Adobe.
http://www.adobe.com/products/reader/

(The green led (light), means standby. The board is receiving 5volts DC.

If you still do not have display just let me know.
Good luck mecompe!

Mag monitor doesn't display bios post


I have no experience with the DVI links because such technology is still unavailable here in Argentina. We have DVI video cards but finding a suitable DVI monitor is another (long) story.
I think that your card (that has 2 DVI ports) is initializing one port first (the primary one) and then, when windows starts, it initializes the other and outputs video from both ports.
Try connecting the monitor in the other DVI port.
If your card has a VGA output, the VGA gets initialized first.
