Thinkpad T21 Boot Problems Problems

I recently replaced a bad fan that was causing the laptop to heat up and a LCD screen display that was no good. However, when I turned on the laptop turns on, you can see the lights go on, the LCD screen doesn't turn on but, the fan works now and after about 27 seconds the laptop beeps twice and shuts off automatically. Any ideas what that may be. Thx!!

This is caused by a system board failure. Take the laptop apart again and check all of your connections. Also make sure the ram and processor are seated correctly. You can also try hooking up an external monitor to see if any errors display. This may be an indication that the video cable connected to the system board is not fully connected.

Why is my lap top screen covered with vertical red stripes/HP Pavilion dv9825nr


Ik EXACTLY why u have lines in ur laptop computer screen. how many years have you had it? if u have had it for quite sometime or someone sat threw, or jumped on it but that would crack the screen if u hae like 1 or 2 lines, idk what side mine were on the left and it started 1 line, 2 lines, 3 lines, now my moms dell laptop that we have had for a loong time has about 8 line 3/4 of the screen. It means that ur computer is about to go on u, it could crash like the hard drive but im 100% sure ur screen is just old and im warning u i would go out if u want ur info and get an external harddrive hook it up with a usb while there are only a few lines and same as a USB just put everything onto an external harddrive. the are cheap now. they are a square and they have to be a bigger GB than what ur Computer has, like if ur comp has 250gb of memory then get a 300 gb external hard drive. U better off getting the external harddrive and get a new laptop and put ur info on it instead of paying like $25 an hr to have a new screen put in plus $300 for the screen. u can geta new one for $300. good luck and that is the problem 1,000,000,000% sure

Im a user of Laptop nc6230 for long time , not i found a problem with my laptop. Same time when i switched on the laptop, i can hear everything sound,fan but the screen remain blank. And some time it...


@rashid386

If you turn the computer ON and you can hear that something's running on the background but there's no display , this is a sign that the screen's FL Inverter (this is the chip that controls the backlight of your LCD) or the LCD screen itself is already wearing out and needs to be replaced. If you can see a background image but there's no backlight - you need to have the FL Inverter replaced. If the screen is all black, you may need to have the LCD screen replaced. If you know your way around the computer, you could order screen replacement here and disassembly guide here.


Good luck.

You possibly have a LCD screen failing, but to be 100% sure, you should hook your laptop to an external monitor, and see if the display is good . Any desktop monitor will work. If your display is good, you know your LCD on your laptop is failing, and if it is the same display as your laptop, you know you have a video chip problem on your laptop motherboard.

Problem with Fan - Dell Laptop Inspiron B130 ?


Hello,

If the fan is dead, then the laptop will shut itself off after a short while to prevent heat damage. It is normal for the fan to spin up when you turn on the laptop and then stop turning. The fan will kick in again when it is needed as heat builds up. The system fan has absolutely nothing to do with the lcd lighting up.......seriously.

If the laptop is running, but the screen goes dark after a few seconds, it sounds more like the backlight on the lcd panel is shot. From what you describe, I assume that your lcd is not 'lit up' at all, but you can see a faint image on the screen. If this is the case, then either the inverter board is shot, or the backlight for the lcd panel is dead. You can try calling Dell at 1-800-www-dell and try to purchase an inverter board. They are cheap, and it would be worth the gamble to buy one, because if the backlight is shot, then you need a new lcd panel - $350+ (the backlight is part of it and not replaceable). The inverter board is located at the bottom of the display module, right behind the dell logo at the bottom of the display. It's quite easy to get at.

Here's a good test. Shut the laptop off, and attach a computer monitor to the 15 pin vga connector at the left side of the laptop. Turn on the laptop and the monitor should show you an image. If not, try holding the blue 'fn' key and press and release the f8 key. This should switch you over to the external monitor. If the laptop works fine when connected to an external monitor but has no image, then it's definitely not the fan, and you should try an inverter board. If still no good with a new inverter board, you can still use the laptop with an external monitor.

Hope this helps!.......let me know how you make out.

The screen was black when turned on but could make out what was on the screen when facing the light


You have 1 of 2 issues...

1.) You have a Bad LCD Bulb.. You can get a replacement LCD Bulb and change the LCD Bulb inside the Display which is cheaper and easier than replacing the whole backlight panel.... LCD bulbs cost around $12 Be careful these bulbs are Fragile and if bent when installing- will break...

2.) You have a failing Power Inverter... this is located just under the screen display panel,, it is a circuit board that the screens lcd bulb plugs into and the display cable plugs into... this inverter board converts the DC power in the laptop back to AC power because the screen needs more power to power the lcd bulb...

Your Problem Is One of These 2 Things... Your Best Bet Is To Test The Power Inverter First - Since It Is The Easier Of The 2 To Replace/Repair

Acer 5810t laptop. screen gone black


Press and hold the Power button for 45 seconds to turn the laptop off.

Then, remove the battery from the battery compartment and clean the metal contacts.
Next, reinsert the Battery and try to turn it ON.

If the display still doesn't come then you may try connecting an external display to check if the Computer is able to produce display and the issue is with the backlight of the LCD screen.


wish u good luck!!!!!!!!!!!

Xps 1330 producing heat My XPS 1330 use to have some heating problems, untill one day it never turn on againg. Technician told me that I have to change the mother. Could be an "self" overheathing problem...


With your laptop producing to much heat, make sure the air vents on your laptop are free of dust, debris, dirt, etc.

Also even though the CPU fan doesn't run all the time, make sure it is at least turning on now and then. If the fan doesn't turn on at all after say like 15 minutes then the cpu fan might be bad and would need to be replaced.

If your fan does turn on and still overheats then its the motherboard that is bad cause its not regulating the voltage that goes thru the board. This can happen when components go bad on the motherboard. I highly doubt its the lcd screen that causes the overheating cause it doesn't produce enough power to heat up hardly at all.

Screen displays for 1 minute then turns black


If you have an HP, you probably have a bad display. They are very bad about that very thing. Where the display hinges are, press on the left hinge just above the keyboard. I have a similar HP and mine has the same problem. I was told a shop that it is the inverter for the display. You might see if there is a shop that can look at it for a small fee.

Screen flickers


If light is good and picture flickers, then it is either a bad LCD ribbon cable, or cable not well placed into connector, or a bad LCD display, usually it is the cable.
If picture flickers like light is dimming out and coming back, then it is the LCD lamp, probably in need of replacement.
In some rare case a faulty Video card is causing the problem.
Usually to fix this you need to take apart LCD display and upper laptop plate, to reveal the display cable.
