X121e randomly wake up from suspended status and real time clock error

Hi all
Previously I considered my x121e suffer from overheating issue and causes real time clock error (RTC). However, after more testing and investigation, I believe the problem is related to other hardware issues and I like to hear people opinion before sending the laptop back to Lenovo.
The machine goes into suspend status either pressing the power button or closing the lid from Windows7 (clean install) without problem. However, it would wake up itself randomly, "beep" twice and screen shows RTC and CMOS checksum error. This happen more often when I am holding the machine (i.e. some movement/vibration). I wonder:
- Is it the RTC battery problem, cause the RTC to wake up the machine?
- Other hardware failure?
The laptop has a clean OS installed/recovered. Latest 1.16 Bios installed. No USB or memory card attached. Ram replaced and not the cause.
Please advise
Howard

Hello,
I am unsure; you would have to contact Lenovo directly and find out how they handle this situation.  They may want the ThinkPad X121e back so they can run thorough diagnostics on it, just in case the problem is something else.  That way it gets fixed the first time.

  • Error: 0271: Real Time Clock Error - Check Date and Time settings.

    Hello all,
    I have lenovo T430s laptop that is configured with Bitlocker encruptions and TPM PIN entry. I don't think that has anything to do with the error msg I am getting but here it is. Error: 0271: Real Time Clock Error - Check Date and Time settings.
    Press Esc to continue or F1 to enter setup. I am unable to get into BIOS or even the login screen for Windows 7.
    Any advice would be appreciated.

    Thanks to everyone for the help.  Just want to close this out.  I had a IBM/Lenovo technician here today and he replaced the CMOS battery.  Upon the change, the computer is fine being reconnected to the dock (the three times I tried it).  So it has been resolved with the battery.  Surprised by the incompatibility claim because I am not having issues now.  Wondering if it's just a USB 2.0 vs. 3.0 thing (and Lenovo trying to sell more peripherals, of course).
    Thanks!

  • Real Time Clock Error - Check Date and Time settings, System CMOS Checksum bad

    Hello everybody,
    Can help anyone to resolve my problem.
    I have an Thinkpad W520 (42823FG), BIOS 8BET60WW 1.4        When I disconect AC power and remove battery and connect again, I see this message on screen:
    "Real Time Clock Error - Check Date and Time settings, System CMOS Checksum bad
    Press Esc to continue or F1 to enter Setup"
    Is this a system board problem or CMOS battery problem ?
    Thank you

    Hello and welcome,
    It's probably (hopefully) just the CMOS battery.  The easiest way to find out is to just replace that battery.
    Page 85 of the Hardware Maintenance Manual:

    Here's an example of the battery.  I'm not recommending (or not) this vendor:

    What is your iTunes version?
    If iTunes 11, have you checked the "Up Next" list? If it is not empty, try if clearing "UP Next" will help:

  • Myself and my partner had a iphones. Since the recent software update he now randomly receives texts from my contacts and also when im sending texts. Is this because we share the same apple id. This didnt happen before the software update.

    myself and my partner had a iphones. Since the recent software update he now randomly receives texts from my contacts and also when im sending texts. Is this because we share the same apple id. This didnt happen before the software update.

    You can both share the same Apple ID for purchases but i suggest one of you use another email for the use of iMessage, Facetime etc.
    It is easy to do, the easiest way is to set up an iCloud email directly from your iPhone. Once set up one of you will use this for iCloud services but both still use the existing Apple ID to make purchases.

  • We purchased a new iPad2 and registered it using a 'new' iCloud email/ID. We are unable to send email from the iPad and iPhone. The error is: Cannot send mail. The user name or password for iCloud is incorrect.

    About ~20 hours later, this ended up solving itself. We can send email using the '.icloud' email from both the iPad and iPhone.  Advise would be 'wait' before you start seeking alteranatives like yahoo, hotmail, etc.  This definitely is a convenient way to keep all your 'cloud' information in a centralized place, including the common email...

    sounds more like Bluetooth rather than moue, but w/o knowing w/o posting mac model type/year we... will... not... know... what you have
    All computers are personal computers, a PC though is also "non-Apple" in common usage.
    Mac also is platform and OS.
    Very confused reading what you are trying to tell us.

    regards

    Hello Prasad,
    Before attending interviews.....First you need to understand general things like CV writing, projects, sub modules etc., you should be gain knowledge on these concepts then you can move further.
    1. CV 2.Projects 3.your strenths in sap (reading..reading...reading....practice...practice...practice)
    2.you please interact with your friends who is on trails, then you can get more information like interview process, methodology, technical etc.,
    I am sending some real time interview tech questions which will useful for you.
    Questions:
    1.When tickets are raised by end users who will give priority? After resolve the tickets who will close the status?
    2.In real time at a time how many normal periods, special periods, MM periods we can open?
    3.What is client dependant & Independent?
    4.How to transport configuration settings from one client to another client or production client, which tools we can use for transport?
    5.Why we donu2019t assign business area to company code?
    6.What is the difference between General GL A/c, Control A/c, Reconciliation A/c & Offsetting A/c?
    Answers:
    1.The priority is generally decided by the Coordinator on the client side. After tickets are resolved, they will have to be closed by the coordinator on the customer site
    2. In FI as many as you wants. In MM only 2 (current month + previous
    3.Certain tables and customizations made in one client will affect the other clients also - then it is cross client i.e, client dependent. While if the changes made in one client has no impact on the other client - it is said to be client independent
    4.Transports from one server to the other can be made with the help of transport requests. When a configuration is done the system generates a request number. First release the task and then release the request. Use TC-SE10 / SE09, SE09: workbench transport; SE10: customizing transport. But currently no such difference actually exists.
    5.because in case of multiple company codes, same business area can be used across company codes. Business area is cross company code, means it is not confined to one company code thatu2019s why we don't assign BA to any of the company codes. It is client dependant, not company code dependant. We can pass values from one company code to any of the BA in that client.
    6.General GL Account are those used for standard posting like for example Income and Expenses Accounts
    - Control Account are basically used for reconciliation between modules like FI and CO, to ensure that both the modules are in sync.
    - Reconciliation Account are those specific covering ADK (A-Assets, D-Customer, K-Vendor). For example a Customer Master would be mapped to a Bills Receivable Reconciliation Account and any transaction that needs to be posted are done against the customer code.
    - Offsetting Account are used for variety of reasons and few examples are Intercompany Postings, at the time of Implementation when TB and Balance sheet are uploaded would be offsetted against a dummy account.
    All the best.....dont forget and pl assign points if useful and if u have any querries pl revert back
    thanks

  • Remote Extractor and Real Time Infocube for SEM BCS

    Hi Experts,
    I have somes doubts about the integration between SEM and BW.
    There is a cycle that have the next processes:
    1.- begin in R/3 with the movements in FI, CO and/or general ledgers
    2.- Activate the extractors standards for replicate/extract data to BW. For example, 0FI_GL_XXXX.
    3.- Configure a method for take the information from BW to SEM.
    4.- My doubt begin here... For take the information from SEM to the real time infocube, where I configure?  What Have I for configure?
    The real time infocube, What is the proposal? Where take the data?  Here, Do the remote extractor begin to apply?
    Thank you very much for your collaboration.
    Regards,
    Jeysi Ascanio

    We're using 0FI_GL_20 to read directly from FAGLFLEXT into SEM-BCS via a BI remote cube.  There are some basic transformations in BI to "populate" the remote cube, then a standard Load from Data Stream in BCS to do final mappings.  In the BCS workbench, just create a source data basis off the remote cube.
    This works at my current project due to fairly low ECC data volumes.  If you are doing any complex mapping on the Company or Fiscal Year / Period infoobjects, you may need to create a inverse mapping routine in the remote cube to transfer selection criteria.  If you see messages in the monitor following a data load such as "xx,xxx of xxx,xxx records ignored", that means that you are reading too much data from ECC and it is only getting filtered on the BCS side.  We had this problem with a custom extractor and adding an inverse mapping routine cut the load from ~5min to 30sec.  (Basically, the custom, template-delivered, extractor only had 0FISCPER, not 0FISCPER3 and 0FISCYEAR, so we would read all 17 K4 periods into BI, map them into BCS, then BCS would throw out the unneeded periods.  Unfortunately, we did not have the option to change the extractor, so this was the best approach.).
    If I had large data volumes, I would use a regular BI basic cube for staging (or possibly a multi-cube with a mix of basic and realtime, depending on the load requirements to BCS).
    If you use 0FI_GL_20, I would strongly recommend you implement OSS Note 1245822, or be on SAP_APPL 603.0002 or later.
    Hope that helps,
    - Chris

  • Problem with DAQmx and Real Time PCI-7041/6040E.

    Problem with DAQmx and Real Time PCI-7041/6040E.
    I have a problem with the Real Time card PCI-7041/6040E, I think it is properly installed because my software run with the traditional NI-DAQ. When I try to use the new DAQmx to acquire one signal, Labview doesn't see any device for de DAQ card 6040E.

    Could Labview RT run with new DAQmx ?
    What can I do to use DAQmx with PCI-7041/6040E?
    Thanks for your help !
