HP 48G: HP 48G - display snoring

Hello

I have a 48G from 1993 that I bought used a few years ago. I almost never use it, but it works. Today, I started it, it seems to be OK - but the display is humming / rustling rather silently.

Something to do against him? Something worrying?

Hi!, @Peter2_1:

Welcome to Forum!

It is fail, ever? You can, replace the batteries (AAA)?

If so, you can try to reset. The back cover, you can back in the left, right, bottom, left and right, four (expansion) rubber buffers.

If you delete all (left or right), in the upper part (opossite where to install the batteries), you can see a hole. This hole is for RESET (R), the calculator. Try, to the point of, trombone, enter to the stop, with the calculator ON.

Other, the procedure is, by simultaneously pressing the keys... WE + F1 + F6. Appear, message... Try to remove the memory? Press YES or no.

If continues, is necessary discharge the capacitor, but he asked, disarm, the calculator.

  • ESXi 5.0.0 623860 and HP Procurve 2810 - 48G grouping/Trunk

    Hello

    I have a VMware ESXi 5.0.0 623860 host running two Windows VM well enough. The host material is an HP Proliant DL 380 G5 server.

    This host is Gbit Ethernet connected to a HP Procurve 2810 - 48G (J9022A) switch via two cables UTP Cat 5e.

    I want to configure an ethernet trunk using the two ports of the switch for fault tolerance and failover disaster link.

    I have telnet switch and configure ports like Trunk3 with TRUNK (not LACP) option as shown in this picture:

    Procurve_Trunks_config.JPG

    To the ESXi side I'll to the vSphere Clent to Configuration-> networking-> vSwitch0-> properties-> Edit-> grouping of NETWORK cards, then set the option Load Balancing on "Route based on the IP hash" as shown in the following image:

    vSphere_ip_hash_config.JPG

    At that time, with or without restarting the software Procurve or ESXi host I ping the host and two virtual machines in it, but after about 10-15 minutes, I lose connectivity to the host (ping stops). So if I disconnect one of the UTP cables connect it again.

    I don't know if these are the good configurations for my goal, so any help would be much appreciated.

    Thaks a lot.

  • HP48G +: 48G repair

I am aware of the new models (still have the old work 41CV - 31 & HP Prime-3 months old. The contacts to get the 48 + fixed it for sentimental value? I'm in Cape Town, SA.

    Hello

    You can try asking on this forum:

    http://www.hpmuseum.org/Forum/Forum-4.html

    This is part of a private Museum of the HP calculator online www.hpmuseum.org

    You can also find other interesting forums: www.hpmuseum.org/forum

    Many users of different generations HP calculators post there.

    However, it may be cheaper (also faster and easier) to buy another for example an online auction site.

  • Snoring-snoring-display led?

    Hello

    I have a Clip of 8 GB and I recently recognized that the screen makes noise (really tiny!) tiny, like his. When the backlight turns off, it stops, too.

    Could this be a simple sign of wear or do I have to wait that it will explode one day?

    Could this be a simple sign of wear or do I have to wait that it will explode one day?

    This noise comes from a switching power supply.  The display needs a higher voltage that the battery provides so a boost converter is used for the power supply.  This is a common technique of circuit for the rails of high voltage for these portable devices outside a lower battery or 4V.  I see these kinds of chips.  What is surprising is that SanDisk used a switching frequency enough to be heard. Which is not common in those days, but could have been done to maintain consumption of energy or low price. If you push enough power through a wire thin and low enough frequencies you can hear it (been there, done that).

    I guess the noise is either tiny inducer in the Clip or even the screen itself.

  • A5120 switch - 48G EI didn't poster not MAC addresses connected to the port card.

    I tried to get connected mac address is displayed under political network for a switch HP A5120. model JE069A. My other switches show mac addresses, but not this model. All are in the same policy in foglight. I don't know if it related software, or something in the configuration of the switch. Any suggestion would be appreciated.

    I think that you may have about the product of network Foglight (SGR) management system.

    If so, your best bet is to post your question in the Forum of Discussion of NMS rather than the Foglight Management System forum.

  • HP 48G

    I have a question about the HP 48 G Calculator: some expressions or a set of numbers are large front appear at the same time on the screen. Is there some sort of scrolling option so that you can get all this?

    Unfortunately, the 48 has no scroll built-in command for viewing quick and easy of the large objects.  However, if you press EDIT (left shift + /), you will be able to scroll the cursor through the object to see it all.  Unfortunately the large objects scroll slowly.  Pressing VIEW (SHIFT-arrow down left) runs the built-in Object Viewer, but it is usually even slower as the Publisher.

    Suggestion: Quick object viewers have been written that you can download and install your 48 g; view http://www.hpcalc.org/search.php?query=viewer & hp48 = 1 for the best of them.

    DISCLAIMER: I do not work for HP. I'm a fan of HP Calculator. I hope that others will also respond here with additional suggestions.

  • Reminders do not display or stick to the lock screen in iOS10

    IOS10 (10.0.1 and 10.0.2), on an iPhone (I use an iPhone 6), reminders are no longer reliable. I had several cases where the callback doesn't show even on the screen lock and many more times when the recall won't 'glue' to screen lock for more than a short period. Before iOS10, when you said to remind you at a certain time or place, the recall would display on the reliable lock screen until she has been marked as "completed".

    It is a major issue for people who depend on the application for the important tasks and calendar. There is a thread of any discussion on this point, for some reason, has been marked as "solved" even if a large number of people continues to post telling him that there is a problem for them too (as the thread located here). I wanted to start this new discussion which we hope will remain open until it is effectively resolved.

    Thank you!!! This is a HUGE problem!

    Since the update I had to reboot my phone EVERY day.

    Is the stick of reminders... or they do not. Lately they don't yet show upward. Then other things stick to the lock screen can't get rid of.

    Currently this feature on the phone is USELESS

    Since I installed Sierra some attachments in the e-mail application do not display you can see that a letter to them.

    Sierra sometimes omits the last accessory and where there is a single attachment is it still missing.

    It seems to fail if the account is configured for IMAP access. POP access is not the problem. Better send Apple. Go to http://www.apple.com/feedback/macosx.html and em let know.

  • Display Rotation error

    Hello

    I had a problem with the rotation of the screen under macOS Sierra function. As the screen rotates, there is an error that pop up and later that I'm unable to get into system-> Display Preferences. It is for me a "mistake preferably: County not load display preferences" message and I was unable to rotate the screen back. I started from the system in safe mode and temporarily solved the problem. But if I want to rotate the screen again, it pops up the same error again. I was using the rotation function pretty well in OS X El Capitan. But since I updated to macOS Sierra, I had this problem.

    I wanted to know if there is a lasting solution to this problem.

    I'm using macOS Sierra on MacBook (13-inch, early 2015) Air with processor 1.6 Ghz Intel Core i5 and 8 GB memory DDR3 at 1600 MHz with 128 GB of storage.

    Hello PavanGJ,

    Thank you for using communities Support from Apple. I see that since upgrading to Mac OS Sierra problems of screen rotation. The preferences window does not. I know how it is important for your Mac to work reliably. I'll be more than happy to help.

    Great job to test mode without failure. In Safe Mode disables most of the third-party services, it could be a compatibility problem with an application that you have. Check out this article:

    OS X El Capitan: If you have problems with startup items

    You can not hold account that the title suggests it's to El Capitan. It applies to macOS Sierra as well.

    You can also test the issue in a new user account.
