Compaq LTE 286

The Compaq LTE286 laptop has to be one of my favorite retro laptops that I own, it might be due to the fact that it was my very first laptop that I owned, it was given to me by a friend who found it in a skip and all it had installed was MS-DOS 3.31, since then I have upgraded it to MS-DOS 6.0 and Windows 2.0 as well as a few CGA dos games.

The laptop is mint condition, the plasma display is bright as it was 10 years ago and amazingly the battery still holds 2 hours of charge.  The only two items I have replaced on this laptop was the Conner Type 53 40MB hard drive which were prone to failure and also CMOS battery which requires the bottom casing to be removed and it’s a bit of a challenge to do as the plastic is quite brittle, I found that pushing sides in then lifting the casing off was the best technique.

The LTE was introduced in 1989 and was one of the first models to be the size of a notebook, thus the term “notebook computer”, the LTE model name was considered to mean “Lite” as a reference to the LTE’s small size and weight of only 3.0kg.

The specifications of the LTE/286 was very impressive at its time of release,  which proved it to be more successful that it’s competitors, one of those features being a built in 40MB hard drive and 1.44MB floppy.

The competing laptops from NEC and Toshiba only had 720KB Floppies and no internal hard drive, the  one downside was that it used a blue backlit plasma CGA (Colour Graphics Adapter) display  with a resolution on 640 x 200 or (80 x 25 lines) compared to 640 x 480 grayscale LCD but seriously, come on the back light on these were blue, Four shades of grey? I don’t think so, these little baby’s pumped out 4 shades of blue!

Helpfull Facts

• The bios on the LTE can only be accessed using the Compaq Diagnostic boot disk.
• The battery pack can be rebuilt using C size rechargeable battery’s.
• The Conner CP4041 Hard drive is prone to failure, so it’s a good idea to preform quick formats instead of a full format so there is less stress on the disc’s platter.
• The hard drives IDE connector is smaller than a regular desktop and laptop connector, I am yet to have seen this connector on another laptop before.
