Lenovo T400 / T500 :: T510 Won't Boot Up (black Screen) After HDD Pulled Out And Put Back Again

Nov 22, 2014

I've just out my hdd to check whether the ssd will fit there, just checked whether the slot is ok. Then I put back the original HHD very carefully. After that I opened the extra RAM slot, took it out and put it back, also VERY carefully. I didn't harm the laptop in any way.

Then I turned the computer on and it was just a black screen, nothing happening. No indicators lighted up, except for power button. I cannot enter BIOS, no response whatsoever.

Lenovo T400 / T500 :: Black Screen On T420s And No Boot

Jun 7, 2013

I have a T420s that I bought a couple weeks earlier, it's a used one, so there's no warranty with it, I used it several days without any issue, I don't use it very frequently as I use my corporate one most of the time.

Someday when I wanted to turn it on, it stacks on a black screen and it beeps one beep then two other, nothing showing on the screen not even the thinkpad logo at startup, I thought it was a RAM related issue so I put the one from my corporate PC but without any luck, so I wanted to see if its graphic controller issue, I plug the VGA cable on the laptop and my TV and here I can see the thinkpad startup logo but after that I see a message on the screen telling :

"Real Time Clock Error - Check Date and Time settings. Press Esc to continue or F1 to enter setup" and when I press either one nothing happen at all, still stacks there.

Lenovo T400 / T500 :: Replace Internal SSD For T510?

Aug 27, 2013

I have a T510 with a 128GB Samsung Solid State drive that is out of space. I would like to replace it with a larger one, preferably a Samsung 840 series with 500GB. I do not want to get an additional drive for the ultrabay, but rather replace the one I have. While shopping and researching, it looks like the drive I have is 78.5 x 54 x 5mm and all of the potential replacements are 100 x 69 x 7mm. Will this fit into the existing drive space? If it will not, what should I get? It also looks like the current drive is SATA II while all replacement options are SATA III.

Lenovo T400 / T500 :: T510 Windows Recovery Failed

Dec 7, 2013

Windows 7 64bit on my T510 has died. When logging in, it hangs on the login screen forever. Windows recovery failed too. It ran for 8 hours and reported error (something like error in restoring a file and disk is full, though my C drive is half empty). After that all the Windows restoration points are gone. So I suppose I have to do factory reset.
 
My question is, I made two additional partitions on my hard drive using external tools, which store all of my data. So when I do factory reset, will these two partitions be overwritten? How I can recover the system while keeping all my data?

Lenovo T400 / T500 :: T510 Very Hot Display Port Cable?

Sep 7, 2010

I was watching a film on my projector, from my Lenovo T510 laptop, using a Display Port to HDMI cable. There was a thunderstorm and a powercut during the film, but my laptop wasnt plugged in at the time. Then when I touched the Display port end of the cable, which is plugged in to my laptop, it was too hot to touch, and had was slightly bulging and mis shapen! Now it has cooled down and just looks and feels normal. Very strange, and I dont see how it could have been related to the storm and powercut, but it seems a bit too coincidental! I have used this cable multiple times before and never noticed this, but then again maybe I wouldnt have ever touched it until it had cooled down. But I it was pretty much metling it was so hot, so I would think Id notice it.

Lenovo T400 / T500 :: T510 / Battery Failed With 99% Capacity

Apr 2, 2011

Recently my T510 9 cell battery suddenly stopped working. According to the Lenovo battery utility, the battery condition is poor and it suggests replacing a battery.
 
However, the battery seems still have 99% capacity, either by Lenovo utility or by other softwares. Before the failing it lasts 3-4 hours and charges normally. 
 
I read several posts online and see some people have similar problems. It is suggested that maybe one of the cells fail so the circuit stopped the battery from working/or the safety circuits just malfunctions? Or indeed I need to replace the battery.
 
I understand that messing with battery is risky and I believe it is detected as not working for a good reason. However,  I am wondering if there is a way to assure that my battery is completely dead, but not a problem with other hardware or the OS, before I purchase a new battery. For example, using a volmeter on the whole batteryto see if I can get a reading, or opening up the battery case and test on each cell? 
 
Is it doable to replace a single cell if one of them fails?
 
PS: For people who says that they connect two terminals of the battery to a volmeter and see no readings, I believe you also need to ground the safety pin to turn on the battery.

Lenovo T400 / T500 :: ThinkPad T510 Low Volume - Windows 7 64bit

Dec 28, 2013

I bought a T510 few days ago and was surprised to see this machine has ridiculously low volume. I have tried everything including the tweaks in Smart audio and removing audio limiter but still the volume is very low. On my dell 1525, I never go past 40% volume on my headphones but on T51o, I am using 90-100% volume to watch videos on live streaming websites.
 
Is there any solution to boost the volume on T510? My system is with windows 7 ultimate (64-bit) and audio device is Conexant 20585.

Lenovo T400 / T500 :: T510 4384-DS9 - Cannot Find Any OPTIMUS Options In The BIOS

Sep 3, 2014

I was originally under the impression that my laptop (Thinkpad T510 4384-DS9) had NVIDIA Optimus display technology, however, I cannot find any OPTIMUS options in the BIOS under display (or any other section for that matter).
 
The reason I would like to know is that I have recently purchased a docking station (model: 4338) and 3 external monitors which I would like to use simultaneously.
 
Forgetting the fact that I'm using Linux, and that for most people this wouldn’t be a challenge worth undertaking, I would just like to know if my system actually supports 3 external monitors and the laptop screen concurrently using the docking station.

Lenovo T400 / T500 :: T510 Dual Monitors No Longer Working Properly

Feb 6, 2009

I have a T510 running Win7 64-bit.  For at least 3 years, I have had the same dual monitor setup (2 DoubleSight DS-1900S) running off my minidock with the laptop closed.  The rgith monitor is the primary, running off the DVI port, while the left uses the analog port.  I was away for a week at Scout camp, powered on the system once while I was there, and when I came back to the office, my monitor setup started failing. 
 
Specifically, the right screen is active but it no longer displays the signal being sent to it.  When I powercycle the screen, I can see the display for about a quarter of a second, then it goes blank.  When the problem first started, I could cycle it about 20 times and eventually it would stay on, until I left the unit overnight and it went to sleep, at which point the probelm started again.
 
Sounds like a wonky monitor?  I have a backup set of monitors that I swapped in, and had the same exact problem, so that appears to rule out a mechanical defect.  More fun facts: I can only use the laptop screen as a standalone display.  I cannot get the multidisplay control panel to open, even though my left screen is powered up.  However, one of my programs that normally launches to my right (main) screen will still launch, but not to my laptop screen.  It really wants to live on my right screen, even when that screen is not powered on (I can close the program by accessing the icon bar at the bottom of my laptop screen).

Lenovo T400 / T500 :: T410 Won't Boot / Blank Screen And Keyboard Unresponsive At Power Up

Dec 23, 2014

my Lenovo T410 laptop won't start. I hit the power button and it looks like it's about to boot up. The thinklight blinks on as normal, the cd drive is checked, the caps lock button blinks on, then nothing. No display, and keyboard is unresponsive. Power light remains on; if I leave it a while the fan comes on. I can turn the machine off using the power button, but the problem remains next time I switch it on.
 
I've tried removing power and battery, pressing power button 10 times then holding power for 30 secs, before replacing power and battery, but nothing happens. I've tried using a different keyboard. I've tried plugging in an external monitor. No change. 
 
This problem appeared after I left it on overnight. I have a hunch that it went into hibernation mode, perhaps, and that it disrupted some important function which it was unable to complete.

Lenovo T400 / T500 :: T440 - Sound Does Not Switch Between Internal Speakers And Headphones Or Back

Mar 15, 2014

How I assume the switch between headphones and speakers should work: I turn on music or anything esle and if no headphones are plugged in, every sound comes from the internal speakers. Now if I plug in headphones then the sound comes exclusively from the headphones. If I pull then out again the sound comes from the speakers and so on.
 
In my case the situation is the following: If I have no headphones plugged in and turn on music, then I hear if via speakers. If I decide to continue listening to that music via headphones and plug them in, then the music continues to come from the speakers, but for example the notification sound from outlook comes from the headphones. This works vice versa.

If I open, say youtube to watch a video, while having the headphones plugged in, I will hear the sound via them. If I now unplugg them, the speakers will stay silent.

What can I do that if there are no external speakers plugged in (headphones etc.) every sound will be played by the internal speakers, if I plug in some sort of external speaker it comes from them and if I unplugg it it switches back to the internal speakers?

Lenovo T400 / T500 :: T410 Monitor Goes Black Intermittently

Oct 21, 2014

Running on Windows 7. I've read similar problems that others have posted, which is the monitor goes black during bootup. My machine boots fine, but every few minutes the monitor goes black / dies - no backlight.
 
This lasts a minute or so, then the display go back to normal. Then it goes black again. Then it goes back to normal. It's not sleeping, the HDD keeps on spinning.
 
I've checked the graphics driver - no update available. I reinstalled it anyway. The built in lenovo utility -thinkvantage- is of no support.
 
At this stage I'm wondering about the integrity of the motherboard.

Lenovo T400 / T500 :: T430S No IP During PXE Boot

Oct 23, 2013

We just bought 15 T430S model N1RLPGE/2356LPG. We install all our notebooks with a running DHCP/PXE environment. A formerly ordered notebook, same type, but an older BIOS (Version 2.02) accurately got itself an IP address during PXE boot and startet the installation. The new T430S (all delivered with BIOS version 2.55) don't even get an IP. I already tried updating the BIOS to the newest version 2.56, but this didn't solve the issue. I checked everything at least twice.

MAC address for IP reservation: correct. Swich (Cisco) portfast is enabled: correct. An older notebook with BIOS 2.02, installing smooth and sound.

When I start the BIOS version 2.56 notebook with a Knoppix DVD, I get the assigned IP address. But not during PXE setup. I also checked the available BIOS and PXE options of the notebook/ethernet card. No options that solved this issue.

Lenovo T400 / T500 :: T420 Won't Boot With New Samsung 840 Pro SSD

Jan 31, 2013

I seem to have a failed brand new SSD. Before I RMA it.

-I've just used Samsung data migration to copy my C drive to a Samsung 840 Pro 128GB SSD as usual.
-I went into device driver, and set the SSD to cache writes, so the SSD was working then.
-I removed the 320GB SSD, installed the SSD and rebooted.
-After the BIOS flash screen, the system halts with a funny symbol on the screen and a flashing cursor.
-It responds to Ctrl Alt Del. but doesn't get as far as testing the DVD drive.
-After replacing the SSD with the HDD and rebooting, all is fine again ...
-The BIOS shows AHCI mode, and the SSD and contents (in a USB3 drive caddy) are visible and readable.
 
I can't use Samsung SSD magician because it won't see the SSD over USB (clever!), so can't work out how to upgrade firmware. This is an i5, 8GB, 320GB machine with 1600x900 screen, with XP Pro 64-bit.
 
What gives?? Others here have posted with working 840 Pros in a T420, so I think it's compatible. Could this be a SATA2/SATA3 thing or AHCI? I can't see any SATA2/3 control in the BIOS - does it just auto-negotiate?

Lenovo T400 / T500 :: Won't Boot (can't Access BIOS)

Nov 9, 2009

I have a T400 2765-P3U model, and it won't boot up.  When you turn it on, you see the Thinkvantage logo and it stays there.  Trying to access the BIOS is non-responsive.  I connected the hard drive to see if it was a hard drive issue, but it's not.  The hard drive is response when connected via USB.  I can't get past the Thinkvantage logo, no response when attempting to access the BIOS.  It's still under warranty, so I'll probably send it in for repair but thought I'd give it a try fixing it before hand.

Lenovo T400 / T500 :: T440s Do Not Boot After Recovery

Oct 8, 2014

I have a T440s lenovo laptop whose motherboard was replaced a few months ago.
 
Today I wanted to make a clean installation (windows 8) using the recover USB key I created before the motherboard replacement (note that I already used it and it was working before changing the board).
 
It goes through the different steps, deleting files and creating the partitions, but when it is done the computer is not able to boot on the hardrive. I have the following messages :
 
Intel (R) Boot agent Ge v1.5.43 copyring (C) 1997-2013 , Intel corporation
............. initializing and establishing link...
 
PXE-E61 - Media test failure, check cable
PXE-M0F - Exiting intel boot agent
(so looks like it is trying to boot on the pci lan)
 
Then it comes back to the boot menu where I have a choice between :
ATA HDD0
PCI LAN
 
If I select the first one nothing happens, and the the PCI LAN gives the above error message.
 
I tried to reset the bios parameters to default but it did not work. So I am wondering if it has something to do with some change in the motherboard ID, bios version....

I also launched the lenovo quick storage device test to check the hard drive and all was ok. I had to change a bios option to UEFI (the new motherboard was set by default to Legacy, messing up all the recovery process)
