Question about Toshiba Satellite 2400-S251 Notebook

1 Answer

NOthing showing up on screen?????

I have had this computer for years and las year, the power kept going out on it, and I realized the end of the power cord that gets inserted into the back of the computer could be the problem, then i looked at the back of the computer (where the power cord goes) and thought maybe there was something wrong with that part instead and tried taking the computer apart. When it wouldnt come all the way apart and I ran out of time, I decided to just put it back together and when trying to use it again the power light came on but when I pushed the button to actually turn the computer on, nothing happened. I can't figure out what i could have done to cause this, or if it just a coincidence and how to fix it so i can get some files and other things out of there...

Hi when you try to take a laptop apart yo have to make srue all the screws went back in the right place if now it may cause the computer to not start no more cause its not grounded right check and mak sure all screws are there nicely not loose and in the right places. also i can back up your files if you send me the hard drive i hav a repair shop. you also could have burnt out the motherboard while trying to take it apart. are you sure its just nto your battery thats dead? or maybe the battery died and the ac adapter no longer works eigther but in most cases its a dc jack problem that may cause it not to charge and what not let me know what happens thank you you can email me at andersonvilletech@gmail.com

Hp pavillion screen is on but screen is dark and keyboard Num lock light is on


If it's a laptop, you can plug in a monitor to see if you can get a signal there. That might tell whether the problem is the graphics card or the screen. There's a Fn/Fkey combination that turns signal on to both monitors; you may need to press that combination to use the monitor.

How do I retrieve photos on my hp pavilion 325c? When I try to turn the desktop on a light blink under the power button


The light blinking under the power button is Hard Drive activity which is normal. Do you have the monitor plugged in and switched on?

Compaq Presario CQ61 will not start. Have removed battery and tried to start with just power cord. Nothing happens. If battery is installed the led with the lighting bolt will flash but laptop still will...


nothing happens, I will take that as no text shows on the screen
at boot (power button on ) time as it did for

CQ61 is not the full model number making accurate answers x10 harder. for any helper, who knows HP gear.
forget that huge battery, no laptop needs it to run on AC power.
most batteries this old are bad. same with the RCT/CMOS coin cell in side. page 55 shows how to replace IT.

http://h10032.www1.hp.com/ctg/Manual/c01740724


The big battery is ALWAYS fix last DEAL. ok?
the blacks screens are 1st always, to diagnose them first.
ill pretend you said CQ61-100 (not 200,300. and so on)
looks like it was made in 2009 .
for 8 long years , you pushed power and saw
"Press the ESC key for Startup Menu" text,
but today, you see 'NOTHING" (nothing is nothing)
does the fan inside blow air and heard ? if not the AC pack is bad.
(wall AC >>>>Pack>>>>19vdc-to-PC)
so that is the black screen of deathh(sic) I call it.
so if the power pack is still good, we do the flash light test.
ever heard of CCFL back lamps, they ended in 2010
(see why my wanting real model numbers matter?)
if it has ccfl lamps they all fail about NOW.
the flash light test.
http://www.pcdied.com/monitors.html#flashlighttest


the black screens of ***** list is here. and tests.
it has many causes. the ABOVE OR top CAUSES. ONLY
THE GOAL IS BIOS SCREENS. "esc" key BIOS is first
the cause of those are . here, 14 steps
remove power pack, and AC pack
push power button, for 10 to 30 seconds this is the HP
magic RESET, (its harmless)
AC PACK back in place. and to wall power hot.(means live power)
NEXT , if the fan works.!
if the fan does not work (say so please) and we can work that FIRST.!!! (in truth fan is first, it must blow )
ever clean out 9 years of lint inside? service it?

http://www.pcdied.com/black-screen.html#Laptop

most CCFL were in fact inside Old C61 PCs.
most.

see this? (this os folks changing them over and over)

https://www.ebay.com/sch/i.html?_from=R40&_trksid=p2380057.m570.l1313.TR0.TRC0.H0.Xcompaq+c61-100+ccfl+lamp.TRS0&_nkw=compaq+c61-100+ccfl+lamp&_sacat=0


They ended these junky CCFL in 2010, phase out.
a key year to not buy PCs older that that Laptops.

Mi lapto tiene la pantalla negra y los del parpadean


this is an English forum? why post Spanish?
you said (goggle translated( so can you)_
I have a hp and just the screen I see black, is not working F9 but it is like it was on and I tried with an external monitor and nothing is seen and the caps lock and end flashes more than six times, the fan does not blow as it should according to me, it blows very low, if it loads correctly, I do not know what happens to it.
answering in italics.
The PC unstated, model is broken, funcionando mal.
you have 2 choices besides , new PC
  1. are get any PC shop to fix it.
  2. or learn how.
which will it be?
#2 is long long course in PC diagnosis or wild expensive guessing.

guess one, its a HP laptop
step one is remove the big battery and check that the PC runs on AC power, wall power. line power.
if yes, the battery is bad,as all do. soon.
soon means less than 20 years, like most parts there last,

still failing try a new power park. (no battery.
im assuming the screen never ever shows text.
even with BIOS keys pressed. per the service manual.

here is a black screen of deathh page , for laptops and other devices, Desktops and monitors.

My old g4 powerbook is dead, power supply seems to be alright , all battery lights come on on the back but nothing from pressing the power button, no noises , black screen....


HI Nick, I had a similar problem with my Titanium G4 Powerbook in the past. The batterry lights showed OK, and at first glance the original Apple transparent saucer shaped power adapter seemed to be working. But then I realized that the very thin conducter wires were broken where the flexible wire meets the connector plug. I cut into the plastic insulation and soldered the wires-a very tedious exercise I might add. This worked for a few weeks, and as I was at sea on a ship, it kept me going. But before long the same problem occurred-an apparent dead computer. I solved the problem by purchasing a 65 watt power adapter from PowerbookMedic. It was dirt cheap and I haven't had a single hiccup since, and that was 3 years ago. You can always see a Genius at an Apple store, if there is one close to your home. These people are amazingly helpful.

Won't start at all


It can be anything from a faulty power jack, to a fried motherboard. Take it back to best buy as soon as you can, and let them take a look. Nothing more you can really do.
