Lenovo L440 - Turn on slow

Q: Lenovo L440 - Turn on slow

Hi, I have a Lenovo L440 and when I turn on my laptop, its take more less 5/6 secs to turn on the screen and show me Thinkpad screen. I compared my laptop whith a same model in my work and I saw that the laptop in my work turn on faster than my laptop (2 secs). Can you tell me if 5/6 it is normal or how I can improve this? I have the last version of the BIOS and I buy a SSD and it is frustrating that the laptop take much time in turn on the screen when windows start very fast. Thanks!,Mati

Hello everyone, about a month ago my lenovo laptop charger died so I ordered one straight away, it took a month to arrive and in the period I used the laptop a couple of times. The battery died so much it got to a critical battery splash screen and wouldnt boot to windows. So for two weeks I left the laptop in my cupboard, when the charger finally arrived I plugged in the laptop AND nothing... There was no light on top of the "i" and the laptop doesn't turn on, I've done the "30 second trick" already and other stuff bun none of them work. Please leave a suggestion and thanks.

A:lenovo L440

Hi Ms,
 
Welcome to Lenovo Community!
 
We understand that your display is not working in your L440 laptop.
 
Issue might be with the LCD cable. Since the external display is working fine there is no issue with the motherboard.
 
Note: As per the Lenovo policy, the warranty will be void if the laptop is dismantled by yourself.
 
We would like you to visit the nearest authorised Lenovo service centre to purchase the power supply.
 
Service Center link - https://support.lenovo.com/in/en/contactus/findaprovider
 
Hope this helps. Do post back if issue persists!
 
Best Regards,
 
Poojitha.

Hello. I have Lenovo L440 laptop. As I remember BIOS is Phoenix. When I turn on my laptop, it makes 1-3-3-1 (1 signal, pause, 3 signals, pause, 3 signals, pause, 1 signal). I could find in Internet what those signals mean. I could find only 1-3-3. Tell me please, what is wrong with my laptop? Thank you. 

A:Lenovo L440 makes 8 signals (1-3-3-1)

Hello and welcome,
 
From the (English) Hardware Maintenance Manual - ThinkPad L440, L540
 
One short beep, pause, three short beeps, pause, threemore short beeps, pause, and one short beep
 
Shut down the computer immediately. Ensure thatmemory modules are installed correctly. If they are, andyou still hear the beeps, have the computer serviced.
 
That would seem to indicate memory issues.

Hi,I have replaced CD-ROM by HDD Caddy with SSD (Samsung 850 EVO 250GB) in my Lenovo ThinkPad L440 (20ASS3GT0) as a second storage device (not one with the OS). When I'm trying to start the system, I'm getting a message "Configuration changes - restart the system." and the system reboots again and again. What is more, I can't access the BIOS any more - pressing F1 does not work. Updating to the newest version of BIOS (1.85) does not help. After removing HDD Caddy everything works fine. I have tried some of the configurations below: Removed the battery, pressed the power button for 10-15 sec. and rebooted with AC Adapter connected - still got message "Configuration changes - restart the system."Removed HDD from standard SATA port and connected it using HDD Caddy - cannot boot into the system. There is no message "Configuration changes...", HDD is detected but it is not on the list with bootable devices (there is only one option to boot over the LAN).HDD Caddy connected with no storage device - boot into the system with no problem.The problem is, that I need two storage devices - one for the OS and second one (using HDD caddy) for another data. Could anyone help me to solve that issue?

Hi, I started having weird after-wake up BSODs (bugcheck: 0x00000133) last week. I don't recall installing or udpating any software (other than Windows update) nor changing hardware configuration.
The BSODs are not regular and don't happen after every wake up, just circa every second third. It seems that they're slightly more likely to happen more times in a row but other than that there doesn't seem to be any way to predict them. Once a BSOD happened during normal use and not immediately after wake up (was about 2 mins after wake up).
The exact way they occur is following: Laptop gets waken up, is normally responsive for about 1-4 seconds, freezes, and after variying amount of time (sometimes seconds, sometimes minutes) fall into BSOD.
Event viewer (system logs) doesn't show anything with the exception of some printer-related problems that have - however -timespamp indicating that they-re after-crash problems. There're no System logs with timestamp in between wake up and crash and the after-reboot ones doesn't provide any useful information.
The laptop runs Windows 8.1 x64 with Ubuntu in dualboot which seems to be unaffected (can't say for sure, don't use it as much).
Crash dump, minidump, and log files: http://1drv.ms/1Cn7RMd

Hi there! I am having problems with my Lenovo s10-3t. I was still able to use it before it didn't turn on. I used it at school and when it notified me that I only have 10% battery left, I turned it off till I reached home and charged it from 11:00pm-1:00am (which I usually do). When I turned it on that morning around 9:30am, it won't turn on anymore. With battery on, the battery indicator will just blink once and will not continue booting. Not even the power indicator nor the hdd indicator will lit. The screen is not displaying anything, no logo, nothing.. Please help me. I did all the suggestions I've searched here in the internet but nothing happens... Thanks!

This laptop won't turn on screen does not even flicker. The power light does come on and the battery does charge. I know this because the light blicks orange if it is charging and eventually goes back to white when complete. I have replaced the mother board and the lcd with absolutely no change. I have removed battery power over night and no change. I've removed both battery and cmos battery overnight and no change. The only reaction other than the power indicator light and charging lights is that the pc will beep when the power adapter plug is inserted or removed. Also, I cannot turn the power off. If i deprees the power button for about six seconds it wil turn off and turn right back on again anfter i release it.

So about 1 month ago, my sister was coming from the kithcen upstairs down with her lenovo laptop in sleep mode, she sent me to bring her charger and so i did. We then plugged thecharger in and tried to turn on the laptop. All that happened was the key board lit up and the cpu fan turns on for about 3 seconds, and the laptop does this in a loop until the battery dies. But it does not do this if you disconect the battery and just use the plug, i have tried so many thing, i have tried disconecting power and battery and holding power for 30 seconds, and then pluging it back in. There was only one issue prior to this and it is that the usb 3.0 port that is mounted on the mother board is broken.Note That the charging light does not turn on. My theory's1. The battery is broken, i did test the battery and on the volt measure it said open loop.(likely)2. The usb 3.0 somehow fried part of the mother board, but not all of it since the cpu fan, power light, and the keyboard still work.(unlikely since a fried mother board nothing works)3. The charger port is broken.(unlikely since the battery does charge, but the laptop does not turn on without a bettery).

Hello.The problem is that when I try to shut down the system it seems to work. Windows 8.1 exits, the screen turns off but the fan is still working, and probably so is the HDD. It does not matter how long I wait, nothing changes. The only way to turn it off ultimately is to hold POWER button but this will damage my HDD.I hope you guys have any solution for this issue.Thank you in advance.

Hello,I've got an annoying problem with my Lenovo Yoga 700 laptop.Today plugged in the charger and started working on my laptop (I'm sure I plugged it in correctly) but I kept gettings messages about low battery level. I checked my charger but I can't really remember if the battery was charging (I suppose not if I was getting those messages). Then my laptop turned off due to low battery power.  When I tried to turn it on (with plugged in charger) I only saw the low battery indicator flash 3 times and nothing. And I thought that my charger was damaged. But It is not! It is because after some reading I decided to open the laptop and unplug the battery. Once I've done that I plugged in the charger and the laptop (without battery) normally turned on! I turned it off and plugged in the battery and it did not turn on now! Even though the charger was working fine (because a minute before I turned the laptop on without any battery plugged in). 2nd try:The laptop works completely fine without the battery. Then I've tried turning on the laptop and while it was running I plugged in the battery. Immediatelly after plugged in the battery the white power light turned off and the orange light was blinking even indicating low battery level, even though my charger was plugged in.Windows was showing that I had 1% battery level and it was not charging.

You can try holding the power button in for a full minute after it shuts off, but if you're not even seeing a splash screen or anything while using the NOVO button, it doesn't bode well. Time to send it in.

Hello there, I just got the same problem this morning with my Y50-70. It suddenly turned off while I was working with Win7, just a black screen, power off. So I tried to power it on again and it failed, simply no reaction at all. The only thing working is the battery LED when the AC connector is plugged in. My Y50-70 is only 5 weeks old and worked without any problems until today ;-( I called the support at Lenovo and they told me to "hard reset" by pulling the power cable and pressing the power button for 20 seconds....no success at all. Finally after several tries I decided to send my Y50-70 back to Lenovo. It seems to be a hardware problem. Lenovo offer 2 years of warranty for the Y50-70, because of that I decided not to open it. Letīs see how long ist takes until I have my - hopefully working- Y50-70 back.Perhaps you have more luck than I.Greetings from Germany!

Hi everyone, I have a H530s, it's about 15 months old but I only used it once or twice a month for a couple of hours each time since I bought it. So it has probably less than 50 hours use on it. About 3 months ago it wouldn't come on after I pressed the power button. Left it for a few weeks as I hadn't time to do anything with it. Tried it again but still dead. Opened it up, all looked normal, tried all connections etc. Still dead. The following week I was about to take it to a pc shop for repair but thought I would plug it in and try one last time, it came on straight away!  Powered up, done all the updates. 3 restarts for installs to complete, ran antivirus checks,  ran diagnostics,  all fine. Computer worked as normal. Next day, dead again. Got a refurbished power supply and swapped it over, still dead. Changed bios battery, still dead. Took ram and graphics card out and tried to power up, still dead. Fast forward two weeks, plugged it in pushed power button and it came on, ran all checks again, all fine. Edited photos, went online, all fine. Turned it off that night, got up and turned it on the next day and it came on first time. Used it as normal to edit photos for a few hours, turned it off when I had finished with it, tried to turn it on the next day and....

A:Lenovo H530s won't turn on. Help.

Hi stuartie007 , 
 
Welcome to the Community Forums. 
 
Seems only thing that you have tried is reseating the processor and reapplying thermal paste. 
Usually it would help doing isolation and reverse check. Since wall sockets and cable are already checked too. 
 
Would the Original Power Suppy work on a different board (or volt meter tested) using verified working power cables ?
Try powering on without the hard drive and memory . Any lights or beeps.  
Check if memory and cpu are working on a different PC if available. 
Check on the systemboard for any loose pins on capacitors , burnt marks , bulges. 
 
Since most service center have available spare parts to counter test the device, it is only then that we can say probable systemboard / power port issue if not the other devices.
 
Update us how it goes. 
 
 
Regards

Hi guys, sorry to make two posts about the same thing, but I couldn't find a delete button for the other :S

Anyway, I have been looking at a Lenovo Z570 laptop for somebody.
It had a fresh install of windows and all drivers where installed and everything in that sense seems fine. The problem is, when you either try and shut down the laptop, or restart the laptop, the computer seems to power down as normal, the screen goes off etc, but, the power light and everything else stays on, and it stays in this state.

I haven't left it for a long time, to see if it turns off itself, but after about 10minutes, I just have to press the power button for it to turn off.

It cannot be software, as I did a clean install myself to see if it would help, and when the computer restarts halfway through the install, I again have to keep hold of the power button to help it through.

I don't know if this is a hardware fault, or could it possibly be a setting that needs changing somewhere?

Thanks in advance

Right now, the power light is flashing when the computer is closed and when I open it, the computer fan seems to start and then immediate shut off.

RELEVANCY SCORE 41.2

My Lenovo Yoga power button recently stopped responding, I really don't know why. I didn't bump the button or do anything to damage it, but it seemed to have stopped working. I read that the rest button was an alternative, so I started using that. Today, that also seemed to stop working. Right now, the power light is flashing when the computer is closed and when I open it, the computer fan seems to start and then immediate shut off. Then the power light is on, but the screen continues to stay black.. The reset button isn't doing anything.  I don't know what to do!!

I have tried a number of different things with pressing the power button in different patterns and intervals and none of them work. When its plugged in the light next to the charge port turns on. But when I press the power button the light for the power button does not turn on. The laptop has no noises that come from the computer when I press the button, and the display doesn't show any light. Any suggestions?
