Lenovo ThinkPad - Popular Questions, Answers, Tips & Manuals


remove the battery large.
then run on AC pack only
#1 top failure of all mobile PC is that battery, so unplug it
then test with AC pack only.
work now.? and all vents must be clean, end to end. not just fan.
there i no fuse it uses current regulator, imagine genius magic electronics fuses that never blow out, and bingo.

OK big battery out, an RTC coin cell fresh.
then fan blows.
next is BIOS, do the BIOS screens work if not the mobo is dead.
have 2 RAM stick on the 2 slots>? try one at a time
run the PC with all modules removed, (options)
remove hdd?
remove, dvd drive.
think like this. Get bios working first
learn that modules can short, and when they do the power regs shut down.
so we unplug all things to the mob,
until only 1 ram and cpu remains.
see? (this is called power overload fault isolation tactics)
even the screen only can be dead, you never mention text showing
you can test the mobo with external screen via that rear (?)_ VGA jack what if that worked, did you learn something here, sure.
this pc has tons of modules to pull, even bluetooth. wifi, sound and more. if you look at all parts inside or sold by ebay, bingo. lots

no boot. SL500 notebook. 10 years old now? 2008 made.

no failed screen photo posted. making answers near impossible to guess what is there on screen.
PC's boot in serial sequence.
Power on
BIOS posts. (power on self test and possible errors)

then asks for BIOS PASSword (bad thing to have and forget) never turn this feature on.
then if Bitlocker was turned on you must get this password next, if lost doom it is for HDD.'

next the HDD boots the OS. (or fails with errors)
what OS is this, windows (what) or Linux (hat) or freedos, or well lots more OS.
let my guess its windows. so the next step is
windows password, is this where you get stuck.


this messages (means recovery mode) in english.
To interrupt normal startup, press the
blue ThinkVantage button"

it is the BIOS hot key for recovery.
if the bios password is not set then BIOS works.

My guess is your HDD is bad, and cant boot.
you read the manual, (did you) and see the recovery chapter. and then attempt the recovery
and that works , good, but if not that means the HDD is bad, or damaged.'
page 41 covers how to use factory recover disk

If you need help , next time tell the helper
what OS came new with PC and was it upgraded.
to say w10. WE CAN NEVER GUESS what
OS is there (operating system)

As it was left with no ventilation underneath for the cooling fan, it has desoldered the GPU.
Motherboard replacement or GPU re ball required.

Try go into BIOS (press F1 after you start the pc). Then F9 for resetting BIOS settings.

sounds like the driver you updated is causing it to shut down.try and start in safe mode and see if you can sort it from there.

If the computer goes into sleep mode, some devices won't wake afterwards. As a test, either disable sleep mode, or open Device Manager, find the adapter or its USB port and set the power properties to not allow the device to turn off to save power.

It really depends on what kind of cold you're talking about. External temperature cool enough to produce condensation in the system can really mess your system up. Even to the point of destroying it. It's always good to keep your system above freezing and even above the dewpoint of where ever you're located.
If you're talking about cold being just starting the computer from any temperature from an "off" power mode to "on" then you could have a video issue. You can check your Event Viewer when it finally powers up to get more info on what caused the problem.

That's correct. I'd recommend to fix it in repair shop rather than on your own if you don't know how to solder.

Traditionally with ThinkPads:

1. The BIOS password can be reset with the CMOS.
2. The Supervisor password cannot.
3. The HD password cannot.

If it's the harddrive that's locked you will have to replace that. If it's the Supervisor password you need to replace the system board which kind of defeats your purpose.

Well there are many reasons but from what you've
said it can only be the Switch itself or your Router's
Firmware needs to be updated.

Go to Start: Type cmd in the command prompt Type
ipconfig press Enter look for the default gateway that's
your Routers IP Type the IP number into your Browsers
url or address bar press Enter. Once inside your Router
or Modem/Router view tabs and look for Update Firmware
Follow Prompts If this does not fix your problem then you
must further look into the Wireless Switch the Light is the
Switches Confirmation that it is Working Properly. Also
a
Driver will not cause this Function to not work and I know
you said the Drivers are Good and pls don't be Mad but has
the Adapter been Enabled with the Assumption your Computer has an RJ45 port for hard wiring.

Stay Positive and We'll Figure this Out.

You need to get a hold of a windows xp recover boot cd/usb. You can download it on the internet (if you can with something else than the lapop)

It might be on a power saving plan. You can change it if you want to but running it on battery while watching movies will drain the battery fast. Anyway, right-click the battery icon on lower right of the screen or search for power options. You can see what plans your laptop is saved to. Choose balanced or high performance or recommended settings.
