Question about IBM ThinkPad R51 Notebook

3 Answers

Laptop screen is barely readable, cannot not determine location of cursor.

I have a IBM think pad R51, I recently borrowed it out and it was returned with a dead battery. I plugged the battery chargeing adapter into the outlet and let charge for a day. When I turn on the laptop the screen is very dull, almost completely unreadable. The laptop appears to be functioning, but I cannot navigate because I cannot see the cursor. Is there a way for me to find out if the problem is the battery or the screen backlight?

    Hi I have a problem with my Dell B130 PC notebook. The computer seems to be running okay but the screen is so dark I can't see the cursor, just the shapes of what's on the desktop. I've never had a problem with it and it hasn't been dropped or anything. Does anyone know what could be causing the problem?

    I have a T20 with a poor battery but even plugged in to AC adapter the screen is very dark.....but the image IS there. The laptop was sitting for a couple of months unused and now has the barely legible screen.

    My thinkpad R51 screen is readable however, it seems that it has some lights out. This occured after taking my laptop home and working on just the battery. I brought to the office and pluged it in. The screen is barely readable. I've found no help in the "help box" in fixing the problem.

    I'm experiencing almost the same. Screen goes to the same dim, unreadable. By pushing the Function F&, screnn comes back on for about 3 seconds, then goes dim. Would this be the screen? Also, when powering up, screen has a red tint to it. Please help and thankyou!

    IBM STINKPAD R51 with dim screen and certain LEDS out. I have read about the inverter and I know about a backlight but why the LEDS out? Bat charge, HDD search, etc.

I've had a replacement screen come in from the vendor directly that was dim from the get go. We removed the casing on the screen and noticed that one of the cables wasnt seated correctly. We pushed it in, heard a click and powered up the laptop again, this time the screen was fine.

Of course if you are not comfortable with removing the screen plating I dont recogmend this, also if your laptop is in warranty your better off just sending it in for repairs.

Screen back light or inverter gone - repair shop for this one

SOURCE: Laptop screen is barely readable, cannot not determine location of cursor.

Remove the battery, plug the ac adapter and try to boot up. This is to check if the battery is the cause. If the issue is still there, while you are on windows, hold down the Fn key then keep on tapping the home key. This is to increase the brightness of the LCD.
If still nothing happens, you may want to try it out on an external monitor just to check if you can seee the cursor. Plug in the external monitor then boot the unit, it should automatically display it on the external monitor, if not press and hold the Fn key then tap F7 to switch displays. Then check if your display setting is set to extended display under display properties, that's why your cursor is gone
Of course if everything fails, you may need to check the FL inverter on the laptop. This will be the bulb light. This bulb rarely busts so you may consider just reseating it to fix the Issue.
Hope this helps.

IBM Thinkpad R51, screen went dark. At the right screen angle, I can see some light from the windows and cursor, but very faint. At that light angle I can maneuver the mouse and click on windows, so all...

The problem
1 The LCD screen is out or
2 The invertor board behind the LCD screen is out or
3 The backlite is out

You have 2 options
1 To use an external monitor for the time or
2 get the laptop fixed by a tech shop

IBM R51 - "Registry Cannot Load"

I had the exact same problem. I basically gave up and decided to reinstall the O.S. But when I did it gave me an option to upgrade rather than install, and I found that all my programs and files were still there after. So you coulkd do that. I found out that some of the O.S. was corrupt via a virus so this was solved also.

Ok so what you need to do is reinstall the Opertaing System. When system 32 files are missing then the Operating System dosent work. You would need to backup any stuff you need. If you have any other questions or need directions please email me at [email protected]

This indicates a possible memory problem. Reseat the RAM modules and boot up, if OK then the laptop is OK.
If not then :-
If you have two RAM modules, remove both and insert one and boot up, if it is OK then repeat with the other one - this will determine which memory module is faulty.

The first thing to check is brightness of your IBM. May be the brightness is set very low. It may sound silly and simple, but we human can overlook simple issue.

Secondly, try using another charger. Not the battery. Recently, I had problems with one of laptop same model. I formatted and reinstalled windows etc...nothing helps. Just curios, changed the charger and surprise me...It worked alright.

Contact IBM service for repairs, I recommend you let someone else do the repairs.

Might not be worth it. You be the judge.
