Lenovo ThinkPad L R/SL :: L540 Shuts Down / Starts Up Fine But Will Not Restart
May 19, 2014
I have a new L540 that arrived inoperatve - power button did not work. Sent it back to depot, and after 2 weeks received it back with a new system board and 3 other parts replaced. After loading Windows 7 without any problems, the first time I went to reboot I found that it hangs after shutting down - in other words, it appears to be shut down, but backlight is still on and there it sits, until I hold power button for 4 seconds. I can hear (very faintly) 5 short beeps as soon as it is down. If I try it in safe mode, the 5 beeps are at full volume.
If I choose "shutdown," it shuts down fine, and comes back up fine after hitting the power button. No difference whether it is on battery, AC, or AC with no battery installed.
I have done all updates including the BIOS, no difference. I have pulled the CMOS battery to reset BIOS settings to defaults.

My problem is that my audio shuts off after a few minutes, then if I want it back I have to restart the PC and it appears fine, but imagine having to restart your computer after initially powering up EVERY time you want to use the PC. The Support assistant says my drivers are up to date which may be the problem due to the fact that I did not have this issue until recently which tells me that one of the automatic updates caused this problem.
Additionally, a problem that was never fixed was that my internet inexplicably drops for no apparent reason. Sporadic problem and has nothing to do with my connection as it as occurred in multiple physical locations. Opening up Internet explorer and clicking "fix connection" works after a few minutes, but this is only a bandaid solution.

Today I received my L540 and I'm installing all the drivers at the moment. After I installed the trackpad/point drivers I disabled the trackpad. But now I noticed that the middle mouse button isn't working.
Also is there an easy way to get all the drivers I'm missing at once? I don't have a CD.

I purchased a new L540 running Windows 7 and enrolled a finger. I can use the fingerprint to unlock but not to login. I've reviewed forum postings that suggest that I need to Change Biometric Settings, however the are set as "Biometrics On, Allow Users to log on to Windows using their Fingerprints." I note that the fingerprint software on the L540 is different than my 2 yr old W520, which had a way different interface.

I have an L540 refurb I got a couple months ago, and the webcam suddenly stopped working. Here's what it looks like when I try to use it anywhere.

Recently I've got an Thinkpad L540 and it's pretty cool.
But I got a problem that when the laptop is booting while a VGA is plugged in, the boot screen (the screen right after when the laptop turns on) will always be shown on the external Display (Projector). I've already checked the BIOS and it is set to "Thinkpad LCD".
I don't know if it'll be fixed with an BIOS update.

My OS is Windows 8.1 last update. I own the Lenovo ThinkPad W540 work station. There is a program called Lenovo Toast and nothing appears or starts when I click on it. I have tried to download Lenovo Toast but have not succeeded. (I did not know where to look for Lenovo Toast ).

Recently, the sound has become unrepsonsive and the speakers will not play any sound on my laptop unless I restart it every time I use it after it has gone to sleep.
Also, the orange button on the mute button does not light up when the speakers are not working.

The audio driver is up to date

Laptop starts, shuts itself off. Sometimes will boot to Windows, then shut off. Now, obviously this thing is toast. But look at that thing..what's with the wire? What's with the huge blob of solder? Did somebody just cobble something up here so it would at least still power on, giving some hope of fixing it? Does anybody here think it's fixable if I replaced that chip? Is it a power mosfet? Sorry no pics of the reverse side as I haven't "progressed" to that point yet.

I have problem with my dell 1525. After a full battery discharge, I plugged the power and tried to turn it on. All the lights turn on, but after a second it goes silent and I cannot see anything on the screen even the dell logo.
I also tried to remove the battery and the power cord, pressed the power button for 30sec, doesn't work.Later today I will try to remove the RAM and then install it one by one to see if the problem may be caused by bad RAM , but I doubt that this is the solution.

I am having a message that says "Genuine Lenovo Battery Not Attached" message that appears after Windows 8.1 starts up. A similar sort of message appears before even Windows boots up, and I need to press the 'Esc' key in order for Windows to boot. This seems to have happened after a recent Windows update. I have uninstalled an reinstalled the Lenovo Power Management Driver but it does not appear to have fixed the issue. My BIOS is the latest version.
This issue is on my Lenovo ThinkPad Yoga S1.

I recently upgraded my Lenovo ThinkPad T400 with a Crucial M500 (240GB SATA SSD 7mm) and 8GB Kit (DDR3 PC3-8500 NON-ECC) RAM.
After a couple of days of trail and error I eventually installed (successfully, I might add) Windows 7 via USB. I leave my laptop on when I sleep, but in the morning it's shut off. When I power it on I get to the Windows did not shut down properly and I always select the "Start Windows Normally" option and additionally Google Chrome informs me that it wasn't shut down properly and restores my tabs.
Why it randomly shuts itself off... Also, when I try to run my system rating after one or two flashes of the screen my laptop turns off, so I am unable to do this as well.

I have a Dell Inspiron 1545. When I turn the laptop on the fan and noises all started but the screen stays black and it completely shuts down. Does not restart itself but shuts down.
I have tried...
- Taking out HDD
- Removing battery
I also have another one of the same laptops and tried using the battery, adapter and hdd. All 3 worked for the other laptop but not this one.

The issue was in regards to WiFi not working properly on my Lenovo ThinkPad Yoga S1. After a restart my computer's internet (with WiFi on) would work for a few minutes then it would stop. Long story short, I tried various things, and even uninstalled Norton and other software which I thought may have been a culprit but still the same issue. I also used a USB to Ethernet port (since there is no built in Ethernet port in the ThinkPad Yoga) and connected my computer with a cable and disabled the WiFi to see if it was the wireless hardware not working. Unfortunately still the same issue.
Finally I noticed in the Windows Task Manager a process called "Discover.exe". It turned out this was using some noticeable amount of CPU and wondered what this was doing as I hadn't seen that before. I found out that this was a piece of software bundled in with my computer called Lenovo EMC Storage Connector. I'm not sure why it was running but I ended this process.
Suddenly my internet was working again! This time no problems. I uninstalled this software utility to make sure this doesn't cause this issue again.

I have a HP G72 250US laptop with Windows 7 (64-bit). Laptop has been intermittently stopping. Screen goes black then shuts down tries to restart and sometimes does but screen is black so can’t see what’s on screen. Other times it just shuts down completely. Sometimes screen goes haywire with bizarre horizontal color lines mixed with strange pixelated graphics then goes black.
After restarting in safe mode and ran CCleaner then performed a Hard Reset which seemed to work for the rest of day but next day within an hour screen flashed, went black then came back on again. This time a notice come up but I clicked it thinking to get more info but only made notice go away. It said something about Intel Graphics Accelerator stopped working and had successfully restarted.
I have Intel HD Graphics Driver version 8.15.10.2086 which is what’s listed on HP for correct graphics driver.

My laptop was working fine but then 5 minutes later after I shut down, I realized I forgot something so I started it back up again to find that after the Lenovo logo screen I would get a Fan Error message and the laptop shuts back down. Now I can't get into my computer at all.

V570 - works great! Upgraded to Win8 but had probs with it so did a "refresh" and that pretty much cleared it up.Bored so got a Sammy 840Pro SSD. Cloned with stand-alone Acronis Trueimage 2013. Boots and works fine. Had the SSD plugged to the eSATA.Then I noticed that on cold startup, it was not giving me the BIOS options of F2 and F12, and pressing them did nothing - it just booted up Win. Did a lot of googling at this point but no joy.I then noticed that on a restart from Win8 , it DID give me the BIOS options and I could get into the BIOS. But that's a dicey way to run!!! I early on (a year ago) found that you cannot re-order the devices in BIOS - it resets them to what it wants. (latest BIOS 44CN36WW which is 43 - an old one)
Okay, so boot order is SATA port specific, I put my second HD into the primary position and hung the SSD off the eSATA cable. It insisted that the SSD was bootable device 8 (LOL) and tried very hard to boot from the Realtek LAN port. However it WAS giving me the BIOS options so I could hit F12 and choose the SSD and boot into windows. I also found that if I pulled the RJ45 before I hit power, it would try the Realtek, but then bounce to the list of devices - choose the SSD, and boot into windows.I moved the SSD to the DVD port (I had an adapter), but exact same thing - still calls it 8.So it works and is a good deal faster than the original Toshiba drive which did 90MB read. But there is that unfortunate pause in my 10-15 sec win boot!

So, I have B590 Lenovo Notebook with Windows 8 and the Wi-Fi doesn't work well.
When I try connect at home, my Wi-fi works fine. Not problem. But when I try another one - e.g. In School or somewhere in the city, the others wi-fis don't work. Windows 8 tell me something like "It's not possible to connect" .....

I have recently purchased Lenovo G50-70 laptops for my office. One of them started to act awkward from yesterday. When I tried to switch it ON, it starts for and then immediately (less than 1 sec) turns off. I have tried to start it several times. I have tried to removed battery, RAM and then tried directly on power, but of no use.
Yesterday it started once and then I was able to use it for like 4 hours, but it didn't starts today morning.

I've just purchased Helix 3702-3LO (i7, 8GB, 128GB, Win8Pro 64bits upgraded to 8.1) and today found some problem. Pictures taken by rear camera are malformed. The picture looks like: [URL] ....
But at the same time video taken by the camera is perfect. So how do you think, is it software or hardware problem?
I've already tried refresh drivers, update what was possible to update, but still no imrovement, I still want avoid sending the computer to the service. It looks like some part of the image (bottom) is paste in the middle. Looks like codecs problem???
But now I'm not sure if it is only software problem or may be some how hardware (video is recorded is fine)..

I have a Lenovo g500 with windows 8.0 Suddenly this month the sound started to stop.
This happens when I start the laptop or if it wakes from standby.
The sound is restored only after a restart. I have already tried microsoft solutions and tested all the services that start with windows start.

Took delivery of my brand new y510p yesterday and the last 24 hours have been hell.The PC is incredibly slow, much slower than my three year old XPS 15 from dell.
The laptop won't shut down/restart.. It just goes through shutdown screen then black screen with keyboard monitor fan etc still on.I have done a system recovery back to initial state and am now running windows updates as first port of call but its been stuck on 13 out of 32 update (whilst shutting down) for the past hour and half.

When I "restart" my Y500 using windows 8.0, it takes a minimum of 15 minutes. Sometimes, if I have time to wait, it takes more than one hour. 90% of the time, I restart it using the on/off button. No problems at all using the button, but the software takes a VERY long time or won't restart at all--just the green screen with the word "restart."
